SMC VHK2A-12F-12F Finger Valve (VHK2A12F12F)
1. Product Overview
The SMC VHK2A-12F-12F is a 2-port, 2-position manual finger valve belonging to SMC’s VHK-A series, designed for manual on/off control of compressed air in industrial pneumatic systems. It features a poppet valve structure with 12mm one-touch fittings on both the supply (P) and actuator (A) ports, making it ideal for quick and easy manual control in applications such as machine tool clamping, fixture positioning, small – bore cylinder actuation, and manual override in automated production lines. With a maximum operating pressure of 1.0 MPa and a proof pressure of 1.5 MPa, this valve offers reliable performance, a small knob operation force, and a clear open/closed indication via the knob direction, facilitating intuitive on – site operation and maintenance. The compact PBT (Polybutylene Terephthalate) body and lightweight design enable flexible installation in space – constrained areas, and its compatibility with nylon, soft nylon, and polyurethane tubing ensures broad applicability in diverse industrial piping setups. It is also RoHS – compliant, meeting international environmental standards for eco – friendly production facilities.
2. Main Functions
| Function | Detailed Description |
|---|---|
| Manual On/Off Air Flow Control | The 2 – port (P/A) configuration enables manual switching of compressed air supply to control small – bore cylinders, grippers, and pneumatic accessories, suitable for manual operation stations and emergency stop systems. |
| Intuitive Open/Closed Status Indication | The knob direction clearly shows the valve’s state (counterclockwise rotation for open, clockwise for shut), allowing for quick visual confirmation during operation and maintenance. |
| Low – Effort Knob Operation | A small operation force of 0.04–0.14 N·m enables easy actuation with one finger, reducing operator fatigue during frequent use. |
| Secure Handle Retention | The handle removal prevention function prevents accidental knob disassembly, ensuring operational safety and reliability in industrial environments. |
| Quick and Tool – Free Tubing Connection | 12mm one – touch fittings allow for rapid, tool – free connection and disconnection of nylon, soft nylon, or polyurethane tubing, minimizing installation time and simplifying system modifications. |
| Residual Pressure Management | When shut, the poppet structure effectively blocks air flow and helps manage residual pressure on the actuator side, preventing unexpected movements of pneumatic components. |
3. Technical Features
- Poppet Valve Structure: The poppet design minimizes seal defects, ensuring long – term airtightness and reliable performance with a service life of over 5 million cycles.
- Large Effective Cross – Section: An optimized internal flow path provides a large effective cross – sectional area, ensuring sufficient air flow for small to medium – sized pneumatic actuators.
- Compact and Lightweight Design: The PBT body offers high durability and chemical resistance while keeping the valve lightweight, enabling flexible mounting in space – limited areas.
- Broad Pressure Compatibility: With a maximum operating pressure of 1.0 MPa and a proof pressure of 1.5 MPa, it can handle a wide range of industrial pneumatic applications, including low – to – medium pressure systems.
- Wide Temperature Range: The operating temperature range of 0–60°C allows for use in various industrial environments, from cool warehouses to warm production floors.
- RoHS Compliance: It meets international environmental standards and does not contain restricted hazardous substances such as lead and mercury, suitable for eco – friendly production facilities.
- Handle Removal Prevention: The integrated design prevents accidental knob removal, enhancing operational safety and reducing the risk of system downtime due to component loss.
- Corrosion – Resistant Components: High – quality O – rings and seals ensure resistance to industrial contaminants, maintaining reliable performance in harsh working conditions.
