Our Certifications

Check valve spool:

It is made of high temperature resistant and environmentally friendly non-toxic silicone gasket. Widely used in tap water, food and beverage industry, etc., can be used with confidence. The valve cores are all made of environmentally friendly materials and have passed the certification of drinking water safety standards such as EU SGS, UK WRAS, French ACS.

working principle


Under static conditions (no flow), the check valve is normally closed because the spring pressure tightly lifts the spool seal to keep the check valve closed.

Under dynamic conditions (normal flow), when the water pressure exceeds the spring resistance. The core is retracted, allowing water to flow through the one-way valve.

In the case of reflux conditions (reverse flow), if the downstream pressure of the valve increases (back pressure condition) or the upstream pressure of the system of the valve decreases (re-siphon condition) to form a back pressure, the spool is closed to prevent backflow.
