Main Product Features

Non-clog design for unrestricted flow and solid handling

The valve features a non-clog design with an unrestricted flow area and smooth streamlined contours that allow the passage of large solids while minimizing the risk of clogging, making it ideal for sewage, wastewater, raw water, and slurry applications.

One-piece fully encapsulated disc for long-term reliability

The one-piece fully encapsulated disc is designed to provide years of trouble-free performance, improving durability and ensuring consistent valve operation in demanding service conditions.

Single moving part for minimal maintenance

The memory-flex disc is the only moving part in the valve, helping ensure long service life, reduced wear, and minimal maintenance requirements over time.

No packing or mechanical components that wear out

The valve is designed without packing, mechanical hinges, pivot pins, or bearings, eliminating common wear points and reducing the need for frequent servicing or part replacement.

Drop-tight seating for reliable sealing at high and low pressures

The synthetic reinforced disc, with its integral O-ring type seal design, provides drop-tight seating and positive shutoff under both high-pressure and low-pressure operating conditions.

Non-slam closure to reduce water hammer

The short disc stroke combined with Memory-Flex™ disc action delivers non-slam closure, helping reduce potentially destructive water hammer and protect the pipeline system.

Backflow actuator option for manual backflow operation

An optional backflow actuator is available when manual backflow operation is required, making the valve suitable for pump priming, back flushing, line draining, and system testing.

Flexible disc action for smooth and quiet closing

The resilient flex action of the disc ensures smooth, quiet, and non-slam closing, improving operating stability and supporting reliable backflow prevention.

 

The rubber flapper check valve is designed with a non-clog full-flow configuration that allows large solids to pass freely while reducing the potential for blockage. Its smooth streamlined body contour improves flow performance and makes it especially suitable for sewage, wastewater, raw water, and slurry applications. A one-piece fully encapsulated disc provides long-term, trouble-free performance, while the memory-flex disc, as the only moving part, ensures extended service life with minimal maintenance.

The valve is built without packing, hinges, pivot pins, or bearings, eliminating common wear components and reducing maintenance demands. Its synthetic reinforced disc with an integral O-ring type seal delivers drop-tight seating and dependable shutoff at both high and low pressures. To protect the system, the valve also offers non-slam closure, with a short disc stroke and flexible disc action that help reduce water hammer. For added functionality, an optional backflow actuator allows manual backflow operation for applications such as pump priming, back flushing, draining lines, and system testing.
