1. Overview of H71 Wafer Lifting Check Valve:

The valve is composed of a valve body, a valve disc, a spring, etc., which are installed horizontally or vertically in the pipeline system to prevent the medium from flowing back. It has a short structure, small size and light weight; the valve disc closes quickly, and the water hammer pressure is small; the flow path is unobstructed, The fluid resistance is small; the action is sensitive and the sealing performance is good.

1 The design specification is in accordance with JB/T8937 API594 API6D

2 Structure length according to JB/T8937 API594 API6D DIN3202

3 4 Valve inspection and experiment according to GB/T13927 JB/T9092 API598
