SMC Handle Pneumatic Manual Control Valve VH311-F03 VH Series, G 3/8 in, III B

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. Renowned for its stable performance and versatile adaptability, this valve series is extensively utilized for circuit on-off and directional control functions in various applications such as automation equipment, machine tools, and pneumatic pipelines.

This series offers valves with two thread connection sizes: 02 (1/4 inch) and 03 (3/8 inch). Moreover, derivative specifications like 02N and R are available to accommodate diverse pipeline installation requirements. The valve body is constructed from die-cast aluminum alloy, enhanced by surface oxidation treatment to provide excellent corrosion resistance. It is engineered to perform reliably within an industrial temperature range of -5℃ to 60℃. The valve core incorporates a dual sealing structure combining a hard seal and an elastic seal, ensuring stable sealing performance and a leakage rate that meets SMC's industrial standards. These valves are suitable for operating pressures ranging from 0 to 1.0 MPa, aligning well with typical pneumatic system conditions.

Structurally and operationally, the VH Series hand rotary valves rely on manual rotary actuation as their primary control method. Featuring clear gear positioning and a smooth rotary feel, the design effectively prevents misdirection issues caused by equipment vibrations. Most models employ a two-position, three-way configuration, while some are compatible with a two-position, two-way function, enabling quick switching and shutoff of pneumatic circuits. Installation is flexible, with options for both panel and base mounting. Selected models come with specialized mounting brackets to suit varied equipment setups.

Additionally, these hand rotary valves are characterized by oil-free lubrication, allowing long-term stable operation without the need for supplementary lubricating oil, thereby significantly reducing maintenance costs. Certain models boast an IP65 protection rating, making them resilient against challenging environments involving dust and moisture. When combined with accessories such as mufflers and pneumatic connectors, the application potential of this valve series expands even further. Overall, the SMC VH Series represents a cost-effective solution for manual control in the realm of industrial pneumatic regulation.

Applications:

The SMC Solenoid Valves, specifically the SMC Pneumatic Rotary Valve series, are highly versatile and reliable components designed for various industrial and commercial applications. As a premier brand, SMC ensures that each valve meets stringent quality standards, backed by CE certification, making it a trusted choice for pneumatic control systems worldwide.

These pneumatic pipeline manual switch valves are ideal for use in systems that require precise control over the flow of dry compressed air. The valves operate efficiently within a working temperature range of -5℃ to 60℃ and can handle working pressures from 0 to 1.0 MPa. It is important to note that the working medium should be free of oil and moisture, as these contaminants need to be filtered out to avoid damage to the valve core, ensuring longevity and optimal performance.

The SMC manual rotary valve type is hand-operated, offering straightforward and reliable manual control in pneumatic pipelines. This makes them particularly suitable for occasions where automated control is either unnecessary or impractical, such as in maintenance operations, emergency shutoffs, or manual override scenarios. Their robust construction allows them to be used in a variety of industrial environments, including manufacturing plants, automotive assembly lines, packaging machinery, and pneumatic tool control systems.

With a minimum order quantity of just one piece, these valves can be procured flexibly according to the scale of your project. Pricing is negotiable to accommodate different purchasing requirements, while packaging is tailored to client specifications, typically shipped in cartons for secure transport. The delivery time is efficient, with dispatch occurring within 1 to 7 working days after payment, supported by multiple payment options including T/T, Western Union, and PayPal.
