Flange vertical check valve H42W

Product Introduction

The H42W and H42Y vertical check valve series products use spring supported valve cores, so they can be installed vertically or horizontally. This product is widely used in pipelines under various working conditions in the petroleum, chemical, pharmaceutical, and power industries.

Design features

1. The short stroke and high sensitivity of the valve disc greatly reduce the time required for the valve disc to close, effectively reducing the water hammer pressure of the vertical check valve.

2. The sealing surface is made of alloy steel or hard alloy, and the matching of sealing materials is reasonable, with a long service life.
