Working pressure range 0 to 1 MPa VH series manual rotary valve featuring robust construction and smooth manual control

Product Description:

The SMC VH Series (including models VH301, VH300, VH312, VH311, VH332, VH330, and VH322) pneumatic hand rotary valves are manually operated directional control components specifically engineered for industrial pneumatic systems. Renowned for their stable performance and versatile adaptability, these valves are extensively utilized in applications such as automation machinery, machine tools, and pneumatic pipelines for controlling circuit on-off functions and directing airflow.

This series offers valves with two thread connection sizes: 02 (1/4 inch) and 03 (3/8 inch). Additionally, derivative specifications like 02N and R are available to fulfill diverse installation requirements across different pipeline configurations. The valve bodies are constructed from die-cast aluminum alloy, providing excellent corrosion resistance after undergoing surface oxidation treatment. These valves are designed to operate reliably within industrial environments ranging from -5℃ to 60℃. Inside, the valve core features a dual sealing structure combining a hard seal and an elastic seal, ensuring consistent sealing performance with leakage rates that comply with SMC’s stringent industrial standards. They function efficiently within a pressure range of 0 to 1.0 MPa, making them well-suited for conventional pneumatic system conditions.

From a design and operational perspective, the VH Series hand rotary valves employ manual rotary control as their primary mode of operation. They include precise gear positioning and a smooth rotary action, which help to prevent control errors caused by equipment vibration. Most models feature a two-position three-way structure, while certain variants also support two-position two-way functionality, allowing for rapid switching and shutdown of pneumatic circuits. Installation options are flexible, supporting both panel and base mounting methods. Some versions come equipped with specialized mounting brackets to accommodate a variety of equipment layouts.

Furthermore, these hand rotary valves boast oil-free lubrication technology, enabling long-term stable operation without the need for additional lubricants, thereby significantly lowering maintenance expenses. Certain models offer an IP65 protection rating, providing resistance against dust and moisture, and making them capable of withstanding harsh working environments. When combined with accessories such as mufflers and pneumatic connectors, the application scope of these valves can be greatly expanded. Overall, the SMC VH Series represents a cost-effective and reliable manual control solution in the realm of industrial pneumatic control.

Applications:

The SMC Solenoid Valves, specifically the SMC Pneumatic Rotary Valve series, are designed to offer reliable and efficient control in various pneumatic systems. Known for their robust construction and CE certification, these valves are widely used in industrial automation where precision and durability are paramount. The product is ideal for applications requiring a pneumatic pipeline manual switch valve to regulate airflow efficiently and safely.

One of the primary application occasions for the SMC two position three-way manual rotary valve is in automated manufacturing lines. These valves allow operators to manually control the direction of compressed air, enabling quick adjustments and maintenance operations without shutting down the entire system. Their working pressure range of 0~1.0MPa ensures compatibility with most standard pneumatic systems, making them versatile across different industries.

In scenarios such as packaging, assembly, and material handling, the pneumatic pipeline manual switch valve plays a critical role. It facilitates the switching of compressed air pathways, allowing for seamless transitions between different operational modes or machine configurations. The hand-operated valve type provides intuitive control, which is essential during troubleshooting or manual overrides in automated environments.

The valves are suitable for use with dry compressed air, as any oil and moisture must be filtered out to avoid valve core damage. This makes them particularly useful in cleanroom environments or industries where contamination must be minimized, such as pharmaceuticals, food processing, and electronics manufacturing. Additionally, the valve's packaging can be customized as per client requirements, ensuring safe delivery and ease of installation.

With a supply ability of 5000 pieces per month and a minimum order quantity of just one unit, SMC provides flexible purchasing options to meet diverse customer needs. The pricing is negotiable, and convenient payment terms such as T/T, Western Union, and Paypal are accepted. Delivery times range from 1 to 7 workdays after payment, ensuring prompt fulfillment.

Overall, the SMC two position three-way manual rotary valve stands out as a dependable pneumatic pipeline manual switch valve ideal for various industrial applications that demand precise manual control of compressed air flow. Its quality certification, versatile working conditions, and ease of operation make it a preferred choice for engineers and system integrators worldwide.
