R-Series / Radial Valve

Plattco’s Radial valve combines all of the features of the H-Series with an airtight radial seat and flapper. The patented radial shape of the seat and flappers allow for a true and tight fit even after extended use to prevent loss of pressure.
Combined with Plattco’s legendary “easy maintenance technology,” this exceptional double-dump valve offers the lowest overall 10 year cost of any other airlock on the market.

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.
• Full throat opening eliminates bridging, jamming and material build-up.
• In pressurized applications, Plattco’s patented mechanical seal eliminates the potential for shaft-seal leakage.
• Seat and flapper can be reground 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.
