HOW THE PISTON VALVE CAN HELP YOUR INDUSTRIAL PROCESS

In an industrial process, valves are used to control flow and pressure in pipelines carrying liquids, gases, fumes, etc.

To this end, we will address here the use of conventional globe valve models and also piston valves.

Conventional Globe Valve

Widely used in industrial processes for fluid flow control and pressure regulation, this type of valve is characterized by its globe-shaped body.

Conventional Globo valves use gaskets as sealing elements. This type of sealing material offers reliability and is recommended for a wide range of industrial applications.

however, the use of gaskets on globe valves, develop recurrent leaks and replacement of this material is necessary. However, this gasket change is hampered by access to it and also by the need to depressurize the entire line, since this maintenance must be done without any pressure on the valve.

This type of valve also uses a gasket between the body and the bonnet. This type of seal may leak and, sometimes, results in erosion of the sealing surfaces, requiring replacement of damaged parts.

Bearing in mind that globe valves also use internal metal type seals / metal, it is possible for leaks to appear, because, considering that this type of fence falls into class IV, dripping is allowed. Besides that, considering that this type of seal does not have the perfect contact, dirt may accumulate on the sealing surface and erosion of these surfaces may occur.

It is important to note that, any loss of vapor must be analyzed and corrected, because it means wasted time, operation and also money.

Loss of vapor through leakage to the atmosphere (kg per hour)

SOURCE: UTILITY LEAK PREVENTION
*THE STEAM JETS ARE MEASURED ONLY IN LENGTH

Considering the table above, that relates the size of the leak jet to the maximum steam flow, if we take as an example a line pressure 9,3 bar, and a jet of steam leak from 90 cm – the vapor loss will be 26,8 approximately kg / h.

Also considering the operating time: 24h / he; 30 days / month – the total steam lost per month will be = 19,3 tons.

Assuming a cost of R $ 60,00 per ton – the total lost will be R $ 1.157,76 a month.

The warning point in the case of the conventional globe valve is that, all these setbacks presented result in a high maintenance cost, waste of inputs and unwanted production stops, considerably harming the cost x benefit of using these valves.

Piston Globe Valves

The Globe Piston valves in turn, present cost x benefit that make the investment feasible.

The piston valve sealing system, occurs through graphite rings that are in contact with the piston. This type of fence, class VI, ensures tightness for both the line and the atmosphere.

The exclusive sealing system of KLINGER piston valves ensures Class VI sealing according to ANSI / FCI70-21 Standards, referring to the passage of fluid to the line.

The efficiency of these graphite rings is given by the insertion of expanded stainless steel sheets and by the special physical properties of the graphite that allow its use in temperatures from -40ºC to 400ºC, being suitable for thermal shocks and vapor changes / condensed.

This seal is based on the contact between the piston (plug) and the inner surface of the seal rings, contact with the lower ring (seat) makes the flow block to the pipe and the contact with the upper ring makes the seal for atmosphere. This contact between the piston and the upper ring replaces the gaskets and the gaskets of the bonnet, that are used in conventional valves.

Piston valves have low cost maintenance, because normally, it is necessary to replace only the sealing rings, items that have a cost of approximately 5% of the cost of the valve. Maintenance is also easier, since the valve can be repaired by keeping the body installed in the pipeline.

Considering the presented characteristics of piston valves, it can be said that this type of valve offers greater reliability against accidents caused by leaks.

Besides that, energy savings and other inputs inherent to the process result in an irrefutable cost x benefit.

In addition to steam and condensate collection systems, the KLINGER piston valve has proven effectiveness in applications such as thermal fluids up to 350 ° C, chemical fluids (stainless steel version) and gases.

This type of valve, also available with special trim for fine adjustment. Yet, this feature is unique to the KLINGER piston valve.

Time for hard resistance

Wear attacks and service life of metal-seated ball valves.

Wear parts are the weak points in ball valve technology. In particular, the ball and ball seats must withstand extreme loads. The spectrum of dynamic wear forces is very extensive and results from the loads of high temperatures, high pressures, high switching frequency, aggressive media, abrasive solid particles, abrasion, erosion, vibration, cavitation and flow velocity.

Tailored and application-specific selection of surface coatings of the ball and ball seats based on hard metal (such as chromium carbide, tungsten carbide, chromium oxide, Tribaloy etc.) improve wear resistance, leakage in the port and the service life.

Characteristics such as good wear resistance or high wear resistance, low cold welding tendency, very good sliding properties, high hardness, high thermal load capacity, good load-bearing capacity at high surface pressure, low adhesive resistance and high adhesive tensile strength characterise the quality of the metallic coating of the INTEC system technology.

An efficient surface coating is dependent on the chemical composition, layer porosity, pore size, layer hardness, structure, adhesion to the carrier material, the inner bond and the layer thickness and its uniformity.

  • Metallic sealing system (floating or mounted ball valve version).
  • Paired ball and ball seats, lapped onto each other.
  • Surface hardness of the coating from 60 up to 70 HRC.
  • Leakage rate A – absolutely gas-tight – continuity tightness 1×10-4 mbar helium.
  • Temperature resistance up to 800°C.
  • More than 12 up to 15 different hard material coatings for the optimal solution.

Next-door Neighbor

CTP-DUMAG benefits from proximity to KLINGER Gebetsroither

CTP-DUMAG can trace its origins back to the 1930s. As a combustion technology expert, it focuses on the manufacturing of industrial burners and lances. Its unique and globally competitive Austrian engineering know-how is also applied to construct entire burner systems. And it has a company address our customers might well be familiar with: Am Kanal 8 - 10 in Gumpolds­kirchen, which is also the address of the KLINGER business park in Lower Austria. Robert Schröger, CTP-DUMAG’s executive manager, tells us how this came about and what it is like to be the next-door neighbor of your supplier.

When we catch up with Robert Schröger, he is in the final preparations of a business trip to Asia. “We are a globally active company with a strong presence in Europe. 70 percent of our sales, however, are generated in China, Thailand and Malaysia,“ explains the executive manager, adding: “We are currently in the process of establishing a second business location in Asia.” The products that form the basis for the upcoming expansion of CTP-DUMAG are industrial burners and lances for a wide range of industries, including the chemical and the petrochemical industry, waste incinerators and energy providers. “Our mission is three-fold,” explains Schröger, “we destroy waste, we reduce CO2 and our technology provides process energy.” Asked about the company’s connection to KLINGER, he states: “I joined the predecessor company DUMAG after the completion of my studies in machine engineering in 1992. Even back then, KLINGER Gebetsroither was already on the vendor list.”

Moving in together

The company, as it exists today, was formed after a merger between CTP and DUMAG in 2011, which also led to new offices being required. Hearing about this, a business partner mentioned that office space was available right next to KLINGER in Gumpoldskirchen. “In the more than 30 years of our collaboration, we never had a single problem with the valves and gaskets supplied by KLINGER Gebetsroither,” explains Schröger, and adds: “The advantages of being very close to such a supplier made the decision a simple one.” CTP-DUMAG uses KLINGER valves and gaskets for the control and combustion systems in its burners and in the meantime has its company seat in the KLINGER business park, where it calls 300 square meters of office space its own. And one of its main suppliers is only around 500 meters away. According to CTP-DUMAG’s executive manager, this leads to numerous synergies: “In our business it is imperative that the equipment manufacturer and his suppliers act in concert. This also includes a lot of flexibility when it comes to the selection of components as well as meeting the required specifications. KLINGER Gebetsroither fulfills all the criteria.”

Executive Manager of CTP-DUMAG

Dropping by

Asked about the most memorable event in the cooperation between CTP-DUMAG and KLINGER, Robert Schröger remembers: “Somewhere between 2012 and 2013 we were awarded a project by the Dow Chemical Company, a major player in the chemical industry. And one of the many advantages of having KLINGER as your next-door neighbor, is that you can hold your acceptance tests for entire plant components there. And this is what we did.” According to Robert Schröger, the outcome was even better than expected. All the tests went flawlessly, and the customer was highly impressed with the level of professionalism and by the precision with which the test were carried out. “Today the Dow Chemical Company is one of our major customers. But the tracks for this positive development were set back then in KLINGER’s test facilities,” explains Schröger. And the success story of the two companies is still ongoing: Acceptance tests are still held on the KLINGER premises on a regular basis and the colleagues from KLINGER Gebetsroither often visit to update Robert Schröger and his team on the latest in sealing technology, valve automation and new standards. Which once again proves that customer proximity pays off – even if it is actually the customer who moves closer to the supplier.
