FAQ - Cast Steel Swing Check Valve 600LBS
Q1: What is a 600LBS swing check valve?
A: A 600LBS swing check valve is a non-return valve designed for ANSI Class 600 pressure rating. It uses a swing type disc that opens with forward flow and closes automatically to prevent backflow. It is manufactured to API 6D, ANSI B16.34, and BS 1868 standards.
Q2: What is the pressure rating of ANSI Class 600?
A: ANSI Class 600 is a medium-high pressure rating, approximately equivalent to PN100. It is suitable for oil, gas, refinery, petrochemical, power generation, and general industrial pipeline systems.
Q3: What materials are available for 600LBS swing check valves?
A: Common body materials include WCB, LCB, LCC, CF8, CF8M, CF3, CF3M, WC6, WC9, C5, C12, 4A, and 5A. Trim materials such as 13Cr, half Stellite, and full Stellite are available to suit different service conditions.
Q4: What end connections are available?
A: 600LBS swing check valves are available with flanged ends (RF) and butt weld (BW) ends. Both are suitable for Class 600 pressure rating in oil & gas and industrial pipelines.
Q5: Is the 600LBS swing check valve suitable for sour service?
A: Yes. NACE MR 0175 compliance is available on request for sour service applications. Please specify this requirement when requesting a quotation.
Q6: What is the difference between a swing check valve and a lift check valve?
A: A swing check valve uses a hinged disc that swings on a hinge pin, suitable for larger sizes and horizontal pipelines. A lift check valve uses a piston / lifting disc that moves along the flow axis, suitable for smaller sizes and vertical pipelines with faster closing response.
