Valve-In-Head (VIH) Filter 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.
