Smc Corporation Vh330-02 Vh330-03 3/8 Vh Series Pneumatic Manual Valve

Product Description:

The SMC VH Series (including models VH301, VH300, VH312, VH311, VH332, VH330, and VH322) pneumatic hand rotary valve is a manually operated directional control device specifically designed for industrial pneumatic systems. Known for its reliable performance and versatile adaptability, this valve is widely used to manage circuit on-off functions and directional control in various applications such as automation equipment, 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 requirements. The valve body is constructed from die-cast aluminum alloy, which undergoes a surface oxidation treatment to provide excellent corrosion resistance. These valves are capable of operating efficiently within an industrial temperature range of -5℃ to 60℃. The valve core features a dual structure combining hard and elastic seals, ensuring stable sealing performance with a leakage rate that meets SMC's industrial standards. Suitable for working pressures from 0 to 1.0 MPa, these valves align well with the conditions found in conventional pneumatic systems.

In terms of design and operation, the VH Series hand rotary valve employs a manual rotary mechanism at its core. It offers precise gear positioning and a smooth rotary feel, effectively preventing incorrect directional operation caused by equipment vibrations. Most models are designed with a two-position three-way configuration, while some support a two-position two-way functionality, allowing for rapid switching and shutoff of pneumatic circuits. Installation methods include panel mounting and base mounting, with select models supplied with specialized mounting brackets to support diverse equipment layouts.

Furthermore, this series is characterized by oil-free lubrication, enabling long-term stable operation without the need for additional lubricants, thereby reducing maintenance costs significantly. Certain models also feature an IP65 protection rating, making them suitable for harsh environments involving dust and humidity. When combined with accessories such as mufflers and pneumatic connectors, the range of application scenarios is greatly expanded. Overall, the SMC VH Series represents a highly cost-effective manual control solution in the field of industrial pneumatic control.
