Check valve can automatically prevent liquid from flowing backwards, the disc of check valve will open under the action of liquid pressure,
liquid flow from inlet to outlet. When pressure on inlet is lower than outlet, disc will close automatically under the action of liquid differential
pressure, self weight factors etc. so as to prevent liquid from returning.

Configurable characteristics:
1. Lifting straightway check valve
Main model is XD.H41S pattern, the structure resembles globe valve, the disc makes lifting action along central port with reliable movement,
generally, it install on horizontal pipeline only.
2. Lifting vertical check valve
Main models are SX.H42S and XD.H40S, and XD.H40S pattern is a new structure, disc is global, common character is disc makes lifting
movement along port of body axes, generally, it must install on vertical pipeline.
3. Swing check valve
Main models such as: XD.H44S, XD.H74S single disc swing type and XD.H76S double discs swing type, the disc makes
revolving movement around axes, the fluid resistance is less than lifting check valve, which suitable for larger bore, installation position is not
restrained, generally, it install on horizontal pipeline.
