Product Description:
The SMC VH Series pneumatic hand rotary valves, including models VH301, VH300, VH312, VH311, VH332, VH330, and VH322, are manually operated directional control components specifically designed for industrial pneumatic systems. Known for their reliable performance and versatile adaptability, these valves are extensively utilized in applications such as automation equipment, machine tools, and pneumatic pipelines for circuit on-off and directional control purposes.
This series offers two thread connection sizes: 02 (1/4 inch) and 03 (3/8 inch). Additionally, derivative variants like 02N and R are available to accommodate various pipeline installation requirements. The valve bodies are constructed from die-cast aluminum alloy, which undergoes surface oxidation treatment to provide excellent corrosion resistance. These valves are built to withstand industrial environments with temperature ranges from -5℃ to 60℃. Inside, the valve core integrates a dual sealing design combining hard and elastic seals, ensuring stable sealing performance and a leakage rate that meets SMC’s industrial standards. They operate effectively within a working pressure range of 0 to 1.0 MPa, making them suitable for conventional pneumatic systems.
Structurally, the VH Series hand rotary valves operate through manual rotary action, featuring precise gear positioning and a smooth turning feel, which helps prevent incorrect valve direction caused by vibrations. Most variants employ a two-position three-way configuration, while some models support a two-position two-way function, enabling rapid switching and shutoff of pneumatic circuits. Installation versatility is provided through two mounting options: panel mounting and base mounting. Certain models also include specialized mounting brackets, allowing compatibility with a diverse range of equipment layouts.
Furthermore, these hand rotary valves are designed with oil-free lubrication, allowing long-term stable operation without the need for additional lubricants, thus significantly reducing maintenance requirements. Some models achieve an IP65 protection rating, granting resistance against dust and moisture, which suits demanding working conditions. When combined with accessories such as mufflers and pneumatic connectors, the application possibilities expand even further. Overall, the SMC VH Series represents a cost-effective and reliable choice for manual control components within the industrial pneumatic control sector.
