PCV-Series / Pollution Control Valve

The PCV-Series flap valve is used in low pressure applications. Replace your existing rotary airlock valves and get reliable, long-wearing performance in applications using highly abrasive or high temperature materials. Our patented design eliminates internal bridging and plugging.

Excellence in Design:

• No rotary action means no need to build clearance (leakage) into the valve.
• Double flaps ensure that the seal is never broken throughout filling and emptying the valve.
• All-cast construction for consistency, proprietary alloys for durability and wear resistence, seat and flapper precision-machined to eliminate air leakage.
• Proprietary design eliminates bridging, jamming and material build-up.
• Seats and flappers can be reground several times to bring them back to “like new” condition and performance.
• Housing is not part of the seal -- allowing it to last for decades in the worst operational environments.
