The HVFF12 Hand Control Valve is a 3-way manual shut-off fitting engineered to control air flow between two 12mm outer diameter (O.D.) pneumatic supply lines. Featuring a rotary control knob, it provides an instant visual and mechanical switch to turn supply air on or off for downstream pneumatic tools, high-flow air cylinders, or valve manifolds.
Designed with an integrated 3-way residual pressure relief mechanism, turning the valve to the "OFF" position isolates incoming compressed air and automatically exhausts trapped air pressure on the downstream side. This safety feature allows operators to perform safe maintenance, hose replacements, or equipment servicing. Built with dual 12mm push-in one-touch tube connections, it provides fast, tool-free installation and a tight seal.
