Bypass mounting to equalize pressures.
Normal yoke bushing furnished with ductility resistant to high melting point of above 2200°F.
Level and weight available to accelerate/decelerate disc closing (swing check).
Designed for maximum flow with minimum pressure drop if possible.
Precision-ground seating surfaces and revolving disc providing a long life.

In the refineries, power plants, utilities and petrochemical/chemical process industries, PK cast steel valves have been regarded as of great importance about their excellent performance and reliability.
By discriminatory blending of carefully selected materials combined with sound design and precision machining/assembly under strict quality controls, PK steel valves have gained general and wide acceptance. The products are manufactured in accordance with ASTM, ANSI, or other international standards.

  • Body and bonnet – Cast with uniform sections, precision machined.
  • Body: Straight through port without recesses except in the seat area – Minimum resistance to flow, turbulence and erosion.
  • Flex wedge: Guide slots in the wedge engage with integral guide ribs in the body, Stem-to-wedge contact close to wedge center – Better sealing, smoother operation.
  • Seal-welded seat ring – Eliminates leakage path between seat ring and body, does not loosen up due to temperature fluctuations or vibration.
  • Stem – One-piece construction with forged T-head – Long service life, smoother operation.
