Manual Pressure Seal Gate Valves

Product Details

Introduction

Manual Pressure seal gate valves are uniquely designed for demanding conditions in sectors of power plant, refinery, oil & gas ,etc.

Features

1.Pressure seal gate valves adopt unobstructed flow channel, which greatly reduces the flow resistance coefficient and energy loss, and significantly improves the service life and performance of the valve.

2.The middle cavity of the valve adopts a pressure self-tightening sealing structure against the rising sealing force due to the cavity pressure;

3.The sealing surface of the valve disc and the valve seat is made of stellite cobalt-based hard alloy surfacing, which has good wear resistance, high temperature resistance, corrosion resistance and scratch resistance.

4.After quenching and tempering and surface nitriding, the valve stem has optimized strength and scratch resistance.

5.The structure of the opening and closing parts can be designed into single wedge, double wedge, parallel double wedge and other forms according to user requirements.

6.Bypass valves are available to cope with over pressurization and pressure locking.
