Product Overview
The WAAL HV series are manually operated hand rotary valves (hand lever valves) designed for directional control in pneumatic systems. Available in 3 position 4 way (HV-02/03/04) and 2 position 4 way (HV-200B) configurations, these valves allow operators to manually control the forward, reverse, and stop actions of pneumatic actuators.
With smooth rotary operation, accurate positioning, and reliable sealing, HV series valves are ideal for applications requiring manual intervention or where electrical control is not available.
