Hand Valve - Manual Lever Control, VH Series VH301-03

Product Description:

The SMC VH Series (including models VH301, VH300, VH312, VH311, VH332, VH330, VH322) is a pneumatic hand rotary valve designed for manual directional control in industrial pneumatic systems. Known for its reliable performance and versatile adaptability, this valve is extensively used to manage circuit on-off functions and directional control in various applications, such as automation equipment, machine tools, and pneumatic pipelines.

The series offers two thread connection sizes: 02 (1/4 inch) and 03 (3/8 inch). Additionally, derivative versions like 02N and R are available to accommodate different pipeline installation needs. The valve body is constructed from die-cast aluminum alloy, which is treated with surface oxidation to provide excellent corrosion resistance. It can operate efficiently within an industrial temperature range of -5℃ to 60℃. The valve core incorporates a dual sealing design—combining hard and elastic seals—to ensure stable sealing performance with leakage rates that meet SMC’s industrial standards. It is suitable for a working pressure range from 0 to 1.0 MPa, aligning with common pneumatic system requirements.

Structurally and functionally, the VH Series hand rotary valve features manual rotary operation as its primary control method. It includes clear gear positioning and a smooth rotary hand feel, which effectively prevents misoperation caused by equipment vibrations. Most models have a two-position three-way configuration, while some also offer compatibility with two-position two-way functions, allowing for rapid switching and shutting off of pneumatic circuits. The valves support two installation methods: panel mounting and base mounting. Select models also come with specialized mounting brackets to fit various equipment layouts seamlessly.

Another advantage of this valve series is its oil-free lubrication design, which enables long-term stable operation without the need for additional lubricants, significantly reducing maintenance costs. Certain models are rated with an IP65 protection level, offering resilience in challenging environments exposed to dust and moisture. When combined with accessories such as mufflers and pneumatic connectors, the application possibilities expand further. Overall, the SMC VH Series hand rotary valve stands out as a cost-effective and reliable manual control component in the realm of industrial pneumatic control.
