Description
Industrial CPVC Check Valves / Non-Return Valves (NRV)
Nikunj Fibre Glass is an established manufacturer and supplier of CPVC Non-Return Valves (Check Valves) in Vapi, Gujarat. Specifically engineered to prevent dangerous reverse flow and protect pumps from back-pressure surges in corrosive chemical lines, our CPVC check valves operate automatically with minimal cracking pressure.
Types of CPVC Check Valves Available
- CPVC True Union Ball Check Valve: Uses a precision weighted thermoplastic ball that automatically seats against an elastomeric seal under reverse flow. Ideal for vertical pipelines and high-purity chemical processes.
- CPVC Swing Check Valve: Features a counterbalanced CPVC clapper disc that swings open with positive line flow and seats instantly under backflow. Delivers high flow volume and low pressure drop for larger line sizes (2″ to 8″).
- CPVC Wafer Check Valve: Ultra-compact wafer design for sandwiching between ANSI 150 flanges in tight pump discharge skids.
