How do Check / Non‑Return valves work?
A check valve allows flow in one direction only, preventing reverse flow that could damage equipment or disrupt processes. It operates automatically using a disc, ball, or piston that closes when flow reverses.
Advantages of Check / Non‑Return valves...
• Prevents backflow
• Protects pumps and equipment
• Operates automatically (no manual control)
• Low maintenance
