Hand Valves, Shut-off Valves

Fittingdeals offers professional-grade hand valves designed for reliable airflow management in pneumatic systems. Our valves provide precise on/off control while addressing different safety and operational requirements:

Three-Directional Control Hand Valve
✔ Safety-First Design

Automatically vents residual pressure when closed
Ensures safe maintenance and adjustments
Prevents accidental re-energization of connected equipment

Two-Directional Control Hand Valve
✔ Closed-System Solution

Maintains system pressure when closed
Ideal for:
- Air supply tanks
- Vacuum piping systems
- Applications requiring pressure retention
