The Hand Slide Valve (HSV Series) is a reliable, manually operated pneumatic component designed for isolating, venting, or initiating airflow in compressed air systems. Operated by a simple sliding or rotary action, this valve provides an easy and secure way to start or stop air supply, making it ideal for use in applications where quick manual intervention is required.

Constructed from high-strength aluminum, brass, or zinc alloy, the HSV Series is engineered for durability and long service life, even in demanding industrial environments. The valve can be installed inline or on panels, with BSP or NPT threaded connections in sizes ranging from 1/8” to 1”. It is designed to handle pressures up to 10 bar (145 psi), and operates efficiently across a wide temperature range.

In safety-focused systems, hand slide valves are often used as isolation or lockout valves, allowing maintenance teams to depressurize equipment safely before performing service. Some models are also compatible with padlock mechanisms for Lockout/Tagout (LOTO) procedures.

Whether in packaging lines, machine tools, or air supply headers, the HSV valve ensures manual control and safety with zero power requirements.
