Description
The VH200 / VH300 / VH400 / VH600 Hand Valve Series is a manually operated pneumatic shut-off valve designed for safe isolation and control of compressed air systems. The valve allows operators to quickly start, stop, and release air pressure within pneumatic circuits while providing a clear visual indication of airflow direction through the handle position.
The VH Series is available in multiple body sizes and port configurations to support a wide range of industrial pneumatic applications. Its robust construction, simple operation, and reliable sealing make it suitable for machine isolation, maintenance lockout procedures, pneumatic control panels, air preparation units, and factory automation systems.
The valve’s ergonomic lever design enables quick manual switching, while the residual pressure relief function helps improve operator safety during maintenance and equipment servicing.
