-A check valve, non-return valve or one-way valve is a mechanical device, a valve, which normally allows fluid (liquid or gas) to flow through it in only one direction;
-An important concept in check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate. Typically the check valve is designed for and can therefore be specified for a specific cracking pressure.
-Reliable, simple structure, easy maintenance, good sealing.
-Energy-saving, operates with medium pressure difference.
-Prevents backflow and accidents, ensures safety.
-Cost-effective, long service life, widely used.
-Types: lift (vertical/horizontal) and swing (single, double, multi-valve).
-Connections: threaded, flange, welded, clamped.
The company plans to purchase advanced production equipment such as CNC lathes, establish a fully intelligent high and low temperature butterfly valve production line, and introduce high and low temperature products

A: Swing check valve, Lift check valve, Tilting check valve and dual plate check valve;
A: As the name suggests, the check valve acts to prevent the reverse flow of the medium.
A: We have flanges(RF, FF, RTJ), Wafer, SW, BW as well as the Thread.
A: The Swing Check valve's operation is automatic and requires no assistance. When the flow exerts sufficient pressure against the disc to overcome the disc's weight, the disc, which is set on a hinge, lifts allowing the flow to continue through the piping system. As the pressure decreases, the disc lowers until its own weight forces it to seat. This prevents the possibility of a reversal in the flow.
These valves should be sized by Engineering to insure there is sufficient flow to keep the valves from chattering. Chattering will caused premature wear which could lead to loss of performance by the valve.
