Tc end nrv valve

About Tc end nrv valve

A TC End NRV (Non-Return Valve), also called a Tri-Clamp Check Valve, is a hygienic one-way valve designed to allow fluid to flow in one direction only and prevent backflow.
It is installed in sanitary process pipelines where contamination, reverse flow, or pressure surge must be avoided.

This valve automatically opens when the upstream pressure exceeds downstream pressure and closes when the flow reverses ensuring smooth, hygienic operation.

Working Principle

1. The valve consists of a spring-loaded disc or ball inside a precisely machined body.

2. When forward pressure is applied, the spring compresses, allowing fluid to pass through.

3. When reverse flow occurs, the spring pushes the disc/ball back to the seat, sealing the passage.

4. The Tri-Clamp (TC) ends allow quick connection and disassembly for cleaning (CIP/SIP).
