The Hand Turn Valve is a manually operated shut-off valve designed to control or isolate the flow of compressed air, inert gases, or fluids in a system. Commonly used in industrial automation, maintenance operations, and machinery line isolation, this valve allows the operator to open or close airflow with a simple rotary motion.

Available in 2/2-way (on/off) and 3/2-way configurations, and in various port sizes like 1/8", 1/4", 3/8", and 1/2" BSP/NPT, the hand turn valve is highly versatile. It features a quarter-turn or multi-turn rotary knob that provides tactile, secure control of flow, even under pressure.

The valve body is manufactured from brass, anodized aluminum, or engineering-grade plastic, depending on the model and application. The sealing is ensured by NBR (standard), with optional FKM (Viton) for high-temperature or chemical applications. With a pressure handling capacity of up to 10 bar, this valve is suitable for light to medium-duty applications.

Whether used on pneumatic equipment, control panels, air supply lines, or test benches, the hand turn valve provides precise, manual flow control, ensuring safety and reliability in both everyday and emergency scenarios.
