A Hand Valve is a manually operated device used to start, stop, or divert air flow in a pneumatic system. These valves play a crucial role in isolating equipment, controlling actuation, and ensuring safety during maintenance or system shutdowns. Operated by a simple knob or lever, hand valves provide a quick and intuitive way to control air flow without electrical or automated input.

Designed for ease of use, hand valves are built with durable thermoplastic or metal bodies, precision-machined internal passages, and reliable sealing mechanisms. They are suitable for both in-line and panel-mounted configurations, and are compatible with standard push-in pneumatic fittings and tubing sizes.

Ideal for use in industrial automation, air compressors, textile machinery, packaging lines, and pneumatic tools, hand valves offer high reliability in controlling air supply manually, helping prevent accidental actuation and ensuring operator safety.

Key Features of Hand Valve:

Design & Construction

• ✅ Manual Control
  Easy-to-use rotary knob or lever provides precise on/off airflow control

• ✅ Body Material
  Available in high-grade plastic (PBT) or aluminum alloy with brass internals

• ✅ Compact Design
  Slim profile for easy integration into tight spaces or control panels

• ✅ Color Indicator
  Often features red/blue handles for visual identification of valve status

Connection & Compatibility

• ✅ Push-to-Connect Ports
  Compatible with standard pneumatic tubes (typically 4 mm to 12 mm OD)

• ✅ Threaded Versions Available
  BSPT (R) and BSPP (G) thread types for flexible installation

• ✅ Mounting Options
  Suitable for both inline and panel mount usage

⚙️ Performance
