H41h lift check valve

Product Overview

purpose:

Lift 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 recommended to install horizontally with the bonnet vertically upward

Product features:

The valve disc of the lift check valve is a check valve that slides along the vertical centerline of the valve body. The lift check valve can only be installed on the horizontal pipeline. The shape of the valve body of the lift check valve is the same as that of the stop valve (it can be used as a stop valve). The upper part of the valve disc and the lower part of the bonnet are processed with a guide sleeve. The valve disc guide cylinder can make the valve disc lift freely along the vertical centerline of the valve body. When the medium flows downstream, the valve disc opens by the thrust of the medium. When the medium stops flowing, The disc falls on the valve seat by its own weight and the thrust of the medium to prevent the reverse flow of the medium.
