Plastic Gas Non Return Valve
Plastic Gas Non Return Valve (NRV) component precision-molded by Active Polymers is a vital safety component engineered for LPG and pneumatic gas regulatory systems. Featuring an ultra-lightweight, micro-machined stem and a precision-lapped conical sealing face, it delivers instantaneous check-valve closure upon the slightest reverse pressure differential, preventing dangerous backflow into cylinders or supply lines. Molded under strict quality control from specialized hydrocarbon-resistant polymers, it guarantees consistent cracking pressure and frictionless linear response.
