TESCOM™ VT 3-Way Air-Operated Valve
VT Series 3-way valve provides high cycle life in a compact design.
Available in 3-way 2-position shutoff and 3-way proportional versions.

The 3-way 2-position shutoff version is ideal for use in component pressure cycle testing, two source selector valve, fill and dump applications (e.g. airbag canister filling, gas spring filling), and emergency shutoff. Suitable for pneumatic and hydraulic applications.

The 3-way proportional version accurately controls the mix or concentration of high-pressure fluids in hydrogen refueling stations or other industrial mixing or diverting applications.
