Industrial Check Valve Dimension Details
Typical Applications of DIN PN16 – PN160 Lift Check Valve
• Small diameter high pressure pipelines: DN50 – DN200 lines requiring reliable non-return protection.
• Vertical pipeline installation: lift check valves are ideal for vertical flow-up installations.
• Pump discharge lines: preventing backflow and protecting pumps in chemical and water systems.
• Power generation: steam, feedwater, and auxiliary high pressure systems.
• Refinery and petrochemical plants: process lines requiring tight shut-off and quick response.
• Sour service: available with NACE MR 0175 compliance on request.
FAQ - Cast Steel Lift Check Valve DIN PN16 – PN160
Q1: What is a lift check valve?
A: A lift check valve (also called piston type check valve) is a non-return valve that uses a piston or disc guided by a stem or guide. When forward flow enters, the disc lifts to open; when flow stops or reverses, the disc drops back onto the seat to close. It is manufactured to DIN 3356 standard.
Q2: What is the difference between a lift check valve and a swing check valve?
A: A lift check valve uses a piston / lifting disc that moves vertically along the flow axis, suitable for smaller sizes and vertical pipelines. A swing check valve uses a hinged disc that swings on a hinge pin, suitable for larger sizes and horizontal pipelines. Lift check valves generally provide faster closing and better sealing.
Q3: What pressure ratings and sizes are available?
A: DIN lift check valves are available in PN16, PN25, PN40, PN64 (PN63), PN100, and PN160, with sizes from DN50 to DN200.
Q4: What materials are available?
A: Common body materials include GS-C25, 1.4308, 1.4408, WCB, LCB, CF8, CF8M, CF3, CF3M, WC6, WC9, C5, C12, and DSS. Various trim materials are available to suit different service conditions.
Q5: What end connections are available?
A: DIN lift check valves are available with double flanged ends (RF, MFM) according to DIN 2501, and butt weld (BW) ends.
Q6: Can lift check valves be installed in horizontal pipelines?
A: Yes, lift check valves can be installed in both horizontal and vertical pipelines. For vertical installation, flow should be upward. For horizontal installation, the bonnet should be on top to ensure proper disc movement. Please confirm installation orientation when requesting a quotation.
