Simplicity in Design. Very few parts. In severe service applications that means fewer possible areas of failure.

    • High Velocity Oxygen Fuel (HVOF) coating used for ball and seat coating. Available coatings are Chrome Carbide and Tungsten Carbide achieving very high hardness values of 70+ HRC , bond strengths of upto 25,000 psi and can be used in applications up to 815 deg C / 1500 deg F. These coatings have extremely good wear and abrasion resistance at high temperature.
    • Integral Metal Seat eliminates potential “behind the seat” leak path.
    • Metallic Body Gasket Design. Unique self energizing and pressure energizing gasket ensures zero leakage during thermal transients.
    • Zero leakage / Tight Shutoff valves.
       
    • Blow out proof stemusing a machined shoulder which ensures stem cannot “blow out” under pressure.
    • Fire Safe design. Inherently Fire Safe due to metal seats and metallic body gasket.
    • Machined Travel Stops. Integral 90 deg stop plate design ensures correct open and close positions.
    • Standard ISO side mounting bracket. Rugged design with ISO 5211 bolt hole pattern enabling on-site actuator mounting and use of standard mounting hardware.
    • Live loaded graphite stem packing ensures that the packing is always energized
    • Bi-directional sealing option available.
    • Specially designed seats to suit specific applications.
