  • PVC body with glass-filled polypropylene disc handles 150 psi water pressure
  • Buna-N liner operates from 32 to 140 °F
  • Lever handle gives direct on/off control with eight bolt holes

4" PVC Butterfly Valve

This 4-inch wafer-style butterfly valve uses a PVC body rated to cell class 12454 and a glass-filled polypropylene disc. The Buna-N liner handles water temperatures from 32 to 140 degrees Fahrenheit at pressures up to 150 psi. A lever operator provides direct manual control over flow isolation.

Suits water treatment and irrigation lines

The valve fits flanges with an 8-hole pattern on a 7 1/2 inch bolt circle and meets ANSI B 16.10, ISO 5752, ISO 5211 and NSF/ANSI 372 standards. It is not intended for services exceeding the stated pressure or temperature limits, nor for media incompatible with PVC, polypropylene or nitrile components.

Handles 150 psi cold water service

At the top of its range the valve manages 140 degree water at the full 150 psi rating. Headroom decreases as temperature approaches the limit, so sustained high-temperature operation near maximum pressure should be reviewed against the material cell classes 12454 and 85580.

Questions about this item

What pipe size and bolt pattern does this 4-inch valve need to match my existing flanges?

It fits a 4-inch pipe with 8 bolt holes on a 7 1/2-inch bolt circle diameter and lug diameters of 22/31 inches.

Can this PVC valve handle the same 150 psi water pressure my older metal valve was rated for?

Yes, it is rated for a maximum water pressure of 150 psi at temperatures between 32 and 140 degrees F.

How do I confirm the lever-operated disc is sealing properly after installation?

Pressurise the line up to 150 psi and check for leaks at the Buna-N liner and flange faces while the lever is in the closed position.
