SMC VH310-03 sealed (3/8) hole on the side VH310-02 sealed (1/4) VH312-F02 Binary Equation (1/4) Hand Valve
Product Description:
The SMC VH Series (including models VH301, VH300, VH312, VH311, VH332, VH330, and VH322) pneumatic hand rotary valve is a manual directional control device specifically engineered for industrial pneumatic systems. Known for its reliable performance and versatile adaptability, this valve is extensively utilized for on-off circuit control and directional management in various applications such as automation machinery, machine tools, and pneumatic pipelines.
This valve series offers two thread connection sizes: 02 (1/4 inch) and 03 (3/8 inch). Additionally, derivative variations like 02N and R are available to accommodate different pipeline installation requirements. The valve body is constructed from die-cast aluminum alloy and undergoes surface oxidation treatment, providing excellent corrosion resistance. It is suitable for industrial environments with temperatures ranging from -5℃ to 60℃. The valve core features a dual seal design combining hard and elastic seals, ensuring stable sealing performance with leakage rates that meet SMC’s industrial standards. It is designed to operate within a pressure range of 0 to 1.0 MPa, making it compatible with typical pneumatic system conditions.
Structurally, the VH Series hand rotary valve employs a manual rotary mechanism characterized by precise gear positioning and a smooth rotary feel, which effectively prevents misoperation caused by equipment vibrations. Most models incorporate a two-position three-way configuration, while some support two-position two-way functions that allow for swift circuit switching and shutdown in pneumatic systems. Installation options include both panel mounting and base mounting, and select models are provided with special mounting brackets to fit diverse equipment arrangements.
Moreover, these hand rotary valves feature an oil-free lubrication design, enabling long-term stable operation without the need for added lubricants, thereby reducing maintenance expenses significantly. Certain models offer an IP65 protection rating, making them capable of withstanding challenging environments involving dust and moisture. When combined with accessories such as mufflers and pneumatic connectors, their application range expands considerably. Overall, the SMC VH Series represents a cost-effective and reliable manual control component within the industrial pneumatic control field.
