Hayward Flow Control Butterfly Valve 8 in PVC EPDM Gear 150 psi

PVC butterfly valve for water systems

This 8-inch lug-style butterfly valve is built for water distribution and treatment lines that need reliable shut-off or throttling. The PVC body and EPDM liner handle a temperature range of 32 to 140 degrees Fahrenheit and a maximum water pressure of 150 psi. It suits plant operators and maintenance crews who want a corrosion-resistant valve for ambient-temperature service.

Gear-operated handwheel with ISO 5211 mounting

The gear-operated handwheel reduces operating torque so the valve can be opened or closed smoothly without excessive force. Lug mounting with eight bolt holes on an 11 3/4-inch bolt circle and 7/8-inch lug diameter lets the valve be installed or removed from one side of the pipeline. Compliance with ANSI B16.10, ISO 5752 and ISO 5211 ensures dimensional interchangeability and standard actuator mounting patterns.

PVC disc and EPDM liner limit thermal cycling stress

The PVC disc and EPDM liner combination minimises heat transfer and resists chemical attack in treated water, reducing seal wear during normal pressure and temperature cycles. No external power or compressed air is required, so the valve adds no electrical load or pneumatic noise to the system. NSF/ANSI 372 and ASTM D1784 cell class 12454 certifications confirm material suitability for potable water contact.
