Swing Check Valves By Materials

SQK A352 LCC Carbon Steel Swing Check Valve are made up of carbon steel and are often used for low temperature applications. The valves come in different types and for different application purposes. The type of valves vary as gate valves, ball valves, safety valves, reducing valves, check valves and control valves.

SQK A105 Forged Carbon Steel Swing Check Valve material has carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum and vanadium in it. The ASTM A105 Gate Valves are forged material made valves. They have excellent strength, wear and tear and higher mechanical properties.

SQK A182 F304L Stainless Steel Swing Check Valve are Bolted body-bonnet joints provided with spiral-wound stainless steel gasket and graphite filler for maximum protection against leaks

SQK A182 F316L Stainless Steel Swing Check Valve contains 18% Chrome; 12% Nickel; 2% Mo; 0.03% C Low Carbon Stainless Steel

SQK A182 F321 Stainless Steel Swing Check Valve with steel body, stainless trim (API Trim No 8 as standard) for E400. 13 or Austenitic Stainless Trim (API Trim No 10 as standard) for E400. 12, ends being flanged to ASME B16.

SQK A182 F321H Stainless Steel Swing Check Valve is Bolted Body-Cover design for valves from Class 800 up to Class 2500. Valves with welded bonnet also available on request,Screwed with a seal-welded body-bonnet design for valves of Class 2500,Bolted body-bonnet joints provided with spiral-wound stainless steel gasket and graphite filler for maximum protection against leaks

SQK A182 F51 Duplex Stainless Steel Swing Check Valve is equivalent to:- UNS31803† and DIN 1.4462 and it is similar to:- 329LN, SAF2205, Uranus 45N. Duplex stainless is a mixed microstructure of austenitic and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades with similar corrosion resistance qualities.

SQK A182 F91 Alloy Steel Swing Check Valve is the a standard Specification for Forged or Rolled Alloy-Steel Pipe ASTM A182 F91 Flanges, Forged Fittings, and Valves and Parts which are meant for High-Temperature Service.

SQK A182 F22 Alloy Steel Swing Check Valve is a low-alloy steel that contains 2.25% chromium. Often used as base metal for clad components, the F22 is also used in the oil patch wellhead applications for products such as hangers, connectors, and block valves, among others.

SQK A350 LF2 Alloy Steel Swing Check Valve are standard specifications for forged carbon steel piping components.

SQK A351 CF3M Cast Stainless Steel Swing Check Valve made up of a material with 21% chromium max and 13% nickel max. These elements along with carbon, manganese, silicon, sulfur, phosphorus and 3% molybdenum in the composition provides the material with excellent corrosion resistance, strength and high temperature capabilities.

SQK A352 LCB Carbon Steel Check Valve are made up of carbon steel and are often used for low temperature applications. The valves come in different types and for different application purposes. The type of valves vary as gate valves, ball valves, safety valves, reducing valves, check valves and control valves.
