Please Note: Only the EPDM Seat Is WRAS Approved – Not the Entire Valve

The TTV Ductile Iron Wafer Butterfly Valves are engineered for dependable performance in water treatment, HVAC, and general industrial systems. Built with a strong ductile iron body and featuring a WRAS-approved EPDM seat, these valves are a practical choice for installations that require safe contact with potable water at the material level — but please note, the complete valve assembly is not WRAS certified.

Offering excellent value without compromising on performance, these wafer-pattern valves fit neatly between PN10/16 or ANSI 150 flanges. The streamlined design helps minimise pressure drop, while the robust disc and resilient seat ensure a bubble-tight seal. Whether operated manually or automated, these valves deliver smooth operation with low torque requirements.
