Piston Lift Check Valves

Introduction

The disc of the lift check valve is located on the sealing surface of the valve seat on the valve body. When the inlet pressure is greater than the sum of the weight of the disc and its flow resistance, the valve is opened. On the contrary, the valve is closed when the medium flows back.

Features

1.Compact configuration 

2.Reliability for high pressure flow

3.Minimized water hammer
