Product Description:
The SMC VH Series hand rotary valves (models VH301, VH300, VH312, VH311, VH332, VH330, and VH322) are pneumatic directional control components operated manually. These valves are specifically designed for industrial pneumatic systems, offering stable performance and excellent adaptability. They are commonly employed for on-off switching and directional control within various applications, including automation machinery, machine tools, and pneumatic pipeline systems.
This series includes valves with two thread connection sizes: 1/4 inch (type 02) and 3/8 inch (type 03). Additionally, derivative variants such as 02N and R are available to accommodate diverse pipeline installation requirements. The valve bodies are constructed from die-cast aluminum alloy, which undergoes surface oxidation treatment to provide strong corrosion resistance. These valves operate reliably within an industrial temperature range of -5°C to 60°C. Inside, the valve cores feature a dual sealing structure combining hard and elastic seals, ensuring stable sealing performance with leakage rates that meet SMC’s industrial standards. They are suitable for working pressures ranging from 0 to 1.0 MPa, aligning well with typical pneumatic system conditions.
Structurally and operationally, the VH Series utilizes manual rotary operation as its fundamental mode. The valves incorporate clear gear positioning and offer a smooth rotary experience by hand, which helps prevent accidental misdirection triggered by equipment vibrations. Most models have a two-position, three-way configuration, with some adapted for two-position, two-way functionality to enable rapid switching and shutdown of pneumatic circuits. Installation is versatile, supporting both panel and base mounting options. Certain models come with specialized mounting brackets to suit various equipment layouts and configurations.
Moreover, these hand rotary valves feature oil-free lubrication, enabling long-term stable operation without the need for additional lubricants. This significantly cuts down on maintenance expenses. Some valves are rated with an IP65 protection level, allowing them to withstand challenging environments with dust and moisture exposure. When used alongside accessories such as mufflers and pneumatic connectors, the range of possible application scenarios is broadened. Overall, the SMC VH Series provides a cost-effective manual control solution within the industrial pneumatic control field.
