Valve-In-Head Housings

Valve-in-head housings incorporate the same rugged design and application features as our Standard 3/4" NPT housings.


The internal valve-in-head allows both inlet and outlet ports to be simultaneously shut-off with a half turn of the handle. This eliminates the need for external shut-off valves. Radial sealing O-rings and sealing surfaces are continuously cleaned each time the valve is used, ensuring leak-proof operation.


Valve-in-head filter housings are available in 10" and 20" lengths and will accommodate a wide range of 2-3/8" to 2-7/8" diameter cartridges and are available with either reinforced polypropylene or clear FDA-compliant Styrene-Acrylonitrile (SAN) sumps.
