H44h swing check valve

Product Overview

purpose:

Swing check valves are widely used in chemical, petrochemical, petroleum, paper, mining, power, liquefied gas, food, pharmaceutical, electronic industry and other fields with relatively clean media.

Installation method:

It is vertical and horizontal. It is recommended not to install it obliquely.

Product features:

The swing check valve is one of the check valve series widely used. The valve disc of the swing check valve is disc-shaped and rotates around the rotation axis, which makes the channel in the valve linear and has small flow resistance. It is suitable for large-diameter occasions with low flow rate and infrequent flow changes. The swing check valve is divided into three types: single lobe, double lobe and half lobe. These three types are mainly divided according to the valve caliber, It can effectively relieve the flushing of the valve disc and valve body seal when the medium flows backward, thus extending the service life of the valve.
