Why Select a Flowserve Plug Valve?

•     PRESSURE BALANCED PLUG VALVES

 Large seating area enhances the Super-H resistance to erosion.

The wide area maximizes the effectiveness of sealant, so that any unlikely seat damage can solve injecting Serck Audco Sealant, restoring the valve zero leakage bubble tight shut-off capabilities without the need of seats replacement.

Moreover, Sealant can inject with the valve in any position and also under pressure, making the valve in-line maintainable.

•     BALL VALVES

The thin seating area can be damaged by the erosion action of the media and the particles contained in it.

Difference between Sealant for Plug Valve and Sealant for Ball Valve

Sealants for Ball Valves valve generally designs to stop leakages on damaged ball valves. To achieve this and since Ball Valves have thin seating areas, sealants are thicker and include a higher percentage of solid fillers in an effort to plug seat damages and not be washed away by pressure.

Futhermore, Sealants for Flowserve Plug Valve designs to provide general lubrication and bubble tight sealing performance. Since plug valves have relatively wide seating areas, sealants can be thinner and still provide zero leakage over several operations.

Using a Ball Valve sealant on a Plug Valve is not recommended. Moreover,The thicker nature (and high percentage of solid fillers) of a Ball Valve sealant will increase operating torques due to the wide contact area between plug and body and even lead to valve jamming if the sealant dries up.

 

    Flowserve Plug Valve Products

    1)  Lubricated Plug Valves – SUPER H

BRAND: Serck Audco

The Super-H Lubricated Plug Valve is a rugged, pressure balanced plug valve designed for demanding oil and gas isolation applications where bubble tight shut-off and reliable operation are critically important.

Super-H Design

Basic design advantages of Flowserve Plug Valve such as metal-to-metal seats and a wide seating area, along with competitive pricing, have made plug valves the product of choice when the valve operates in a difficult or dirty service and/or needs to open against full differential pressure. The robust metal-to-metal seats ensure long valve life on any service, even in presence of solid particles in the line media.

 Features and Benefits

Benefits

• Certainty of zero leakage sealing down the line, even with damaged metal seats.

     2)  Lubricated Plug Valves – DOUBLE ISOLATION

BRAND: Serck Audco

The Double Isolation Lubricated Plug Valve is a reliable, double isolation plug valve with two independent obturators in a single body. It is ideal for double block and bleed applications.

Design Features

• Same face-to-face as one valve.
• In-line emergency stem sealing
• In-line sealant injection point
• Choice of mounting positions for actuators and handwheels.
• Bleed port.
• Bleed valve flange interface

 Benefits

•  Improved plant and personnel safety assured by a double isolation design that allows the operator to verify valve isolation before carrying out maintenance
• A cost-, space- and weight-saving alternative to a double block and bleed system using two valves in a series
• Ease of installation from a compact design with the same face-to-face dimensions as a single valve, often replacing it without the need for pipe work modifications
• Greater process control via a pressure balanced design that provides a true bubble-tight double isolation capability within a single valve body

     Sample Applications

The valves illustrated are 8” class 1500 Double Isolation Plug Valves in 25% Cr. Duplex with hub ends. The valves are installed on a flowline header application. Morover, in this case one isolation is by electric actuator and the other isolation is by gear operator. Criteria for selection: true bubble tight isolation and space and weight saving over conventional ball or gate valves and minimum maintenance.

The valves illustrated are 4” class 300 flanged in Carbon Steel and Stainless Steel. The application is on a fuel skid and both plugs on each valve are lever operated. Criteria for selection: double block and bleed with true bubble tight isolation for reasons of safety, reliability and minimum maintenance.
