Product Description:
The SMC VH Series, which includes models VH301, VH300, VH312, VH311, VH332, VH330, and VH322, is a pneumatic hand rotary valve designed for manual directional control in industrial pneumatic systems. Known for its stable performance and versatile adaptability, this valve series is extensively utilized for circuit on-off functions and directional control across various applications such as automation machinery, machine tools, and pneumatic pipelines.
This 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 crafted from die-cast aluminum alloy and undergoes surface oxidation treatment to ensure excellent corrosion resistance. It performs reliably within industrial temperature ranges from -5℃ to 60℃. The valve core features a dual-seal structure combining hard and elastic seals, delivering stable sealing efficiency and leakage rates that comply with SMC’s industrial standards. It is suitable for a working pressure range of 0 to 1.0 MPa, making it compatible with standard pneumatic system requirements.
Structurally and operationally, the VH Series hand rotary valve utilizes manual rotary action with precise gear positioning and a smooth turning feel. This design helps prevent misoperation caused by vibrations in the equipment. Most models incorporate a two-position three-way configuration, while some are also compatible with two-position two-way functionality. This enables quick switching and shutdown of pneumatic circuits. Installation can be carried out using either panel mounting or base mounting methods, and select models come equipped with specialized mounting brackets to suit diverse equipment layouts.
Moreover, the VH Series features oil-free lubrication, allowing for long-term stable operation without the need for additional lubricants, which significantly reduces maintenance efforts and costs. Certain models boast an IP65 protection rating, providing resistance against dust and moisture, thereby ensuring dependable performance even under harsh conditions. When combined with accessories such as mufflers and pneumatic connectors, the range of potential applications widens. Overall, the SMC VH Series offers a cost-effective solution for manual pneumatic control within industrial environments.
