Introduction

Check valves are automatic valves, which are mainly used in pipelines where the medium flows in one direction, and only allow the medium to flow in one direction to prevent accidents.


Features

1.The middle cavity of the valve adopts a pressure self-tight sealing structure. The higher the pressure in the inner cavity, the better the sealing performance.
2.Both ends can be connected by butt welding, which is suitable for different pipe connection requirements.
3.The valve pressure bearing parts are made of high-quality heat-resistant alloy steel, which has good high-temperature performance, high pressure resistance, durability, safety and reliability.
4.The sealing surface of the valve disc and valve seat is made of stellite cobalt-based hard alloy surfacing welding, which is wear-resistant, high temperature resistant, good scratch resistance and long service life.
5.The valve disc rotates around the pin shaft outside the valve seat to reduce the violent impact when closing.
6. The built-in pin structure reduces external leakage points and is more reliable in use.
