A series of API BS 1868 Swing Check Valves is rugged, durable, and known for its quality, integrity, and longevity.
Seals are tight and easy to operate with these valves. Valve can be flanged at one end and bolt weld at the other, with pressure classes ranging from ASME Class 150 to Class 2500 and a variety of materials of construction.
A swing-type check valve has a bolted-cover construction. BS 1868 and API 600 specifications, including the thickness of shell walls, are met.
Cast steel ASME B16.34 Swing Check Valves Pressure Seal Bonnet design
A pressure seal bonnet design is used on ASME B16.34 Swing Check Valves and Y Type Swing Check Valves for high-pressure applications. Thermal power plants, fertilizer plants, oil refineries, and petrochemical plants frequently use these valves in high pressure and high temperature steam, chemical, oil, gas, and water applications. Carbon steel and alloy steel valves are available in buttweld ends and come with pressure ratings of 900, 1500, and 2500.
