Flomatic 2433VFD 888VFD 5" Silent Wafer Check Valve – VFD Compatible

The Flomatic 2433VFD 888VFD 5" silent wafer-style check valve is an epoxy-coated ductile iron check valve featuring Flomatic’s patented VFD design for use in variable frequency drive pumping systems. This model incorporates a 316 stainless-steel poppet and seat with an EPDM resilient seal for quiet, non-slam operation.

Specifications:

Body: Epoxy-coated ductile iron

Poppet & Seat: 316 Stainless-Steel

Seal: EPDM (resilient, drip-tight)

Design: Silent, spring-assisted, VFD-compatible

Max Pressure: ASME 150#: 300 PSI @ 150°F / ASME 300#: 500 PSI @ 150°F

Max Temperature: 200°F (93°C)

Connection: 5" Wafer, ASME 150# / 300#

Weight: 21 lbs

Operation: The spring-assisted poppet begins closing as flow decelerates and fully seats at zero velocity, minimizing reverse flow and hydraulic shock. The patented VFD design helps reduce valve chatter and wear commonly associated with variable speed pump operation.

Applications: Municipal water systems, booster pump stations, HVAC, irrigation, and industrial pumping systems utilizing variable frequency drives.

Flomatic Quality: For more than five decades, Flomatic has engineered and manufactured check valves trusted worldwide for reliability, performance, and long service life in demanding pumping applications.
