Working pressure range 0 to 1 MPa VH series manual rotary valve featuring mostly two position three way S port type for flow control

Product Description:

The SMC VH Series (including models VH301, VH300, VH312, VH311, VH332, VH330, and VH322) pneumatic hand rotary valve is a manually controlled directional control device specifically engineered for industrial pneumatic systems. Known for its reliable performance and versatile adaptability, this valve is extensively utilized in applications involving circuit on-off functions and directional control within environments such as automation machinery, machine tools, and pneumatic piping systems.

This series offers two primary thread connection sizes: 02 (1/4 inch) and 03 (3/8 inch). Additionally, it includes derivative variations like 02N and R to accommodate different pipeline installation needs. The valve body is constructed from die-cast aluminum alloy and undergoes a surface oxidation treatment to provide excellent corrosion resistance. It is designed to operate efficiently within temperatures ranging from -5℃ to 60℃, making it suitable for various industrial environments.

The valve core features a dual-structure seal combining both hard and elastic seals, which guarantees stable sealing performance. The leakage rate meets SMC’s rigorous industrial standards. This valve supports a working pressure range from 0 to 1.0 MPa, aligning well with the demands of typical pneumatic systems.

Structurally, the VH Series valves employ a manual rotary mechanism as their primary mode of operation. They come with clear gear positioning and offer a smooth rotary hand feel, effectively preventing directional errors caused by vibrations. Most models are designed as two-position, three-way valves, although some can function as two-position, two-way valves. This flexibility enables quick switching and shutoff of pneumatic circuits. Installation options include both panel mounting and base mounting, with specific models equipped with special mounting brackets for diverse equipment configurations.

Furthermore, the VH Series hand rotary valves feature oil-free lubrication, allowing them to operate reliably over extended periods without the need for additional lubricants, which significantly lowers maintenance expenses. Certain models boast an IP65 protection rating, making them capable of withstanding challenging conditions such as dust and moisture exposure. When combined with accessories like mufflers and pneumatic connectors, the range of possible applications expands even further. Overall, this series represents a cost-effective and dependable solution for manual control within the sphere of industrial pneumatic technology.
