FAQ - Cast Steel Swing Check Valve 150LBS
Q1: What is a 150LBS swing check valve?
A: A 150LBS swing check valve is a non-return valve designed for ANSI Class 150 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 150?
A: ANSI Class 150 is a low pressure rating, approximately equivalent to PN20. It is suitable for water treatment, low pressure oil & gas, HVAC, and general industrial pipeline systems.
Q3: What materials are available for 150LBS swing check valves?
A: Common body materials include WCB, LCB, CF8, CF8M, CF3, CF3M, WC6, WC9, C5, C12, 4A, and 5A. Various trim materials are available to suit different service conditions.
Q4: What end connections are available?
A: 150LBS swing check valves are available with flanged ends (RF) and butt weld (BW) ends. Both are suitable for Class 150 pressure rating in water, oil & gas, and general industrial pipelines.
Q5: Is the 150LBS 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.
