Product Details

A ‌lift check valve‌ is a type of ‌check valve‌ designed to allow fluid flow in ‌one direction only‌ and prevent backflow. Its core mechanism involves a ‌guided disc or piston‌ that lifts vertically off its seat when flow moves in the forward direction and settles back down to seal against the seat when flow stops or reverses.

Technical Standard:
1.Design Standard: GB/T 12235.
2.Face to face: GB/T 12235/ASME B16.10.
3.Flange Standard: EN1092-2/ASME B16.1 .
4.Test Standard: GB/T 13927/API 598.

Product Advantages&Our Service:
1.Self-Cleaning:‌ Turbulent flow around the disc helps sweep debris away from the seat.
2.‌Tight Seal:‌ Precision-machined seats provide reliable shutoff.
3.‌High-Pressure Capability:‌ Robust metal designs handle extreme pressures/temperatures.
4.‌Vertical Installation Required:‌ Typically installed in ‌vertical pipelines with upward flow‌ (like ball check valves). Gravity aids closure.
5.‌Quieter Than Ball Check Valves:‌ Less prone to "slam" due to guided, controlled movement (but not as quiet as silent check valves).
6.Adopt epoxy painting,stronger adhesion and good weather resistance.
7.Pressure Testing Report,3.1 Certificate of Material can be provided.
