Dry Compressed Air Working Medium SMC Solenoid Valves Hand Operated Valve Working Pressure Range 0 to 1 MPa Performance in Pneumatic Equipment

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 engineered for industrial pneumatic systems. Known for its reliable performance and versatile adaptability, this valve series is extensively employed for circuit on-off functions and directional control within various applications such as automation equipment, machine tools, and pneumatic pipelines.

This collection of hand rotary valves offers two thread connection sizes: 02 (1/4 inch) and 03 (3/8 inch). Furthermore, derivative specifications like 02N and R are available, enabling flexible installation to accommodate different pipeline configurations. Constructed from die-cast aluminum alloy, the valve body benefits from surface oxidation treatment, which significantly enhances corrosion resistance. Designed to operate efficiently within an industrial temperature range of -5℃ to 60℃, these valves are well-suited for demanding environments. Internally, the valve core features a dual sealing structure comprising a hard seal and an elastic seal, ensuring stable sealing performance and a leakage rate that meets SMC’s industrial standards. The valves are compatible with working pressures ranging from 0 to 1.0 MPa, aligning perfectly with standard pneumatic system requirements.

From a structural and functional standpoint, the VH Series hand rotary valves employ manual rotary operation as their primary control mechanism. The design includes precise gear positioning combined with a smooth rotary hand feel, which helps prevent misdirection caused by equipment vibrations. The majority of the models feature a two-position, three-way configuration, while some can also perform as two-position, two-way valves. This versatility allows for rapid switching and shutdown of pneumatic circuits. Installation options are flexible, with support for both panel mounting and base mounting. Additionally, several models come equipped with specialized mounting brackets to fit a variety of equipment layouts.

Another notable characteristic of this valve series is its oil-free lubrication capability, enabling stable long-term operation without the need for additional lubricating oil, thereby significantly reducing maintenance costs. Certain models also achieve an IP65 protection rating, making them suitable for harsh environments subject to dust and moisture. When combined with accessories such as mufflers and pneumatic connectors, the range of possible applications expands even further. Overall, the SMC VH Series represents a cost-effective and reliable solution for manual control in the realm of industrial pneumatic systems.

Applications:

The SMC Solenoid Valves, specifically from the SMC Pneumatic Rotary Valve series, are designed to offer reliable and efficient control solutions in various industrial and automation applications. These valves, certified with CE standards, ensure quality and safety compliance, making them suitable for demanding environments. With a working pressure range of 0~1.0MPa and a temperature tolerance between -5℃ and 60℃, they are adaptable to a wide range of operating conditions.

One of the primary application occasions for the SMC solenoid valves is in pneumatic systems requiring precise manual control. As a pneumatic pipeline manual switch valve, these valves enable operators to manually regulate the airflow within pneumatic circuits, ensuring optimal performance and safety. Their design as mostly two position three-way valves allows versatile switching between different air pathways, making them ideal for on/off control and directional flow adjustments.

In manufacturing plants and automated assembly lines, the SMC two position three-way manual rotary valve plays a crucial role in controlling pneumatic actuators and cylinders. It facilitates manual intervention in automated processes, allowing maintenance personnel and operators to override automatic functions when necessary. This capability is especially important during system setup, troubleshooting, or emergency shutdowns, where manual control ensures operational integrity.

The valves are also widely used in laboratory equipment, packaging machines, and material handling systems where precise pneumatic system manual control valve functionality is required. Their capability to handle dry compressed air—while requiring oil and moisture filtration to protect the valve core—ensures longevity and consistent operation in clean air environments.

From an operational standpoint, these valves boast a quick delivery time of 1-7 work days after payment and a supply ability of 5000 pieces per month, catering efficiently to both small-scale and large-scale orders. The minimum order quantity is just 1 piece, allowing flexibility for clients with varying demands. Pricing is negotiable, and payment terms include T/T, Western Union, and PayPal, facilitating smooth and secure transactions.

Packaging is handled with care, typically in cartons or as per client requirements, ensuring the valves arrive in perfect condition ready for immediate use. Overall, SMC solenoid valves offer dependable manual control solutions for pneumatic systems across diverse industries, combining robust performance with convenient procurement and application versatility.

Packing and Shipping:

All SMC Solenoid Valves are carefully packaged to ensure protection during transit. Each valve is individually sealed in anti-static and moisture-resistant packaging to prevent damage and contamination. The products are then placed in sturdy, custom-fitted boxes with adequate cushioning materials such as foam or bubble wrap to minimize movement and absorb shocks.

For bulk orders, valves are organized in designated trays or compartments within larger cartons to maintain order and prevent collisions between units. Each package is clearly labeled with product details, handling instructions, and shipping information to facilitate smooth logistics and inventory management.

Shipping is conducted through reliable carriers with tracking options to guarantee timely delivery. Special handling requests, such as expedited shipping or fragile item care, can be accommodated upon request. Our shipping process ensures that SMC Solenoid Valves arrive safely and in optimal condition, ready for immediate use.
