Product Description
The Festo VHER-P-H-B43C-M5 hand lever valve is a compact manually operated directional control valve designed for dependable pneumatic switching in industrial automation systems. As part of the VHER series, this valve combines robust construction, direct actuation, and precise flow control in a compact package suitable for demanding production environments.
Its 4/3-way closed-center configuration makes it particularly useful where operators require manual control of pneumatic actuators while maintaining a neutral blocked position. The valve is commonly used in food processing equipment, packaging machinery, process automation systems, and machine tool applications.
Key Features
- 4/3-way closed-center valve function — blocks ports in the neutral position for controlled operation.
- Manual hand lever actuation — simple and reliable operator-controlled switching.
- 170 l/min nominal flow rate — suitable for compact pneumatic circuits.
- Rotary switching valve design — durable operation with positive switching action.
- M5 pneumatic ports — easy integration into small pneumatic systems.
- Directly actuated valve — no pilot pressure required for operation.
- Exhaust air can be throttled — supports controlled exhaust flow management.
- ATEX Zone 2 and Zone 22 approved — suitable for selected hazardous environments.
- Wide temperature range from -20°C to +80°C — reliable operation in varied conditions.
