SMC Pneumatic Rotary Valve Series VH300-N02-R with sealed (1/4) hole on the side

Product Description:

The SMC VH Series pneumatic hand rotary valve, including models VH301, VH300, VH312, VH311, VH332, VH330, and VH322, is a manually operated directional control device specially designed for industrial pneumatic systems. Known for its stable performance and adaptability, this valve series is extensively utilized in automation equipment, machine tools, and pneumatic pipelines to manage circuit on-off functions and directional control.

This series features two thread connection sizes: 02 (1/4 inch) and 03 (3/8 inch). Additionally, it offers derivative variants such as 02N and R to suit diverse pipeline installation requirements. Crafted from die-cast aluminum alloy, the valve body undergoes surface oxidation treatment to provide excellent corrosion resistance. It is capable of functioning efficiently in industrial environments with temperatures ranging from -5℃ to 60℃. The valve core incorporates a dual seal structure combining hard and elastic seals, ensuring reliable sealing performance and a leakage rate that meets SMC's industrial standards. Operating within a pressure range of 0 to 1.0 MPa, it is well-suited for typical pneumatic system conditions.

Structurally and functionally, the VH Series utilizes manual rotary operation as its primary mode, featuring clear gear positioning and a smooth rotary hand feel. This design effectively prevents misdirection caused by equipment vibrations. Most valves in this series employ a two-position, three-way configuration, while some models also support a two-position, two-way function, allowing rapid switching and shutdown of pneumatic circuits. Installation options include panel mounting and base mounting, with certain models equipped with special brackets to accommodate varied equipment layouts.

Moreover, the VH Series valves are designed for oil-free lubrication, enabling long-term stable operation without the need for additional lubricating oil, which significantly reduces maintenance expenses. Certain models boast an IP65 protection rating, making them resistant to harsh conditions such as dust and moisture. When paired with accessories like mufflers and pneumatic connectors, the range of application scenarios expands further. Overall, this series presents a cost-effective manual control solution ideal for industrial pneumatic control applications.

Applications:

The SMC Solenoid Valves, particularly the VH series manual rotary valve, are widely utilized in various industrial applications due to their reliable performance and versatile functionality. These pneumatic control manual rotary valves are essential components in pneumatic systems where precise control of air flow is necessary. Their design as SMC two position three-way manual rotary valves makes them ideal for controlling the direction of compressed air in automated machinery and equipment.

One common application scenario for the SMC manual rotary valves is in automated manufacturing lines. Here, the valves regulate the flow of dry compressed air, ensuring smooth operation of pneumatic actuators and cylinders. Since the working medium must be free from oil and moisture, these valves are often paired with filtration systems to maintain optimal functionality and extend the valve core’s lifespan. This is critical in industries such as automotive assembly, electronics manufacturing, and packaging, where precision and reliability are paramount.

Another significant usage occasion is in pneumatic control systems used in laboratory and testing equipment. The hand-operated valve design of the VH series manual rotary valve allows for easy manual intervention and adjustment, making it suitable for scenarios where occasional manual control is required alongside automated processes. The compact design and CE certification assure compliance with international safety and quality standards, making these valves a trustworthy choice for critical applications.

SMC’s pneumatic rotary valves are also extensively used in fluid control systems within HVAC and refrigeration industries. The ability to handle a working pressure range of 0 to 1.0MPa provides flexibility in various pressure conditions, while the two position three-way port type enables efficient air routing and control. Their robust construction and adaptability make them suitable for both new installations and maintenance replacements.

With a minimum order quantity of just 1 piece and flexible pricing available through negotiation, customers can easily procure the exact quantity needed. Packaging is done in cartons or as per client specifications, ensuring safe delivery.
