Safety Notes
Output is enabled only when both buttons are pressed simultaneously within 0.5 ثواني.
Operating pressure must be 0.25–1 MPa; below 0.25 MPa, safety performance is not guaranteed.
Used on hazardous machines such as presses, shears, and benders to prevent hand injuries.
SMC two-hand control valves (mainly VR51 series) require simultaneous operation of both hands to start equipment, preventing crushing, pinching, or shearing injuries caused by operators reaching into danger zones with one hand. They are mainly used on machinery with crushing, punching, shearing, or mold-closing hazards.
Typical Equipment
- Pressing & forging equipment
Mechanical presses, hydraulic punches, high-speed presses
Bending machines, shearing machines
- Plastics & die-casting machinery
Injection molding machines, بثق
Die-casting machines, rubber molding machines
- Welding & assembly equipment
Resistance welders, spot welders
Automated press-fit assembly machines
- Woodworking & metalworking machinery
Wood planers, panel joiners
Riveting machines, crimping machines
- Other hazardous motion equipment
Hydraulic/pneumatic clamping units
Mold opening/closing and heavy press mechanisms
Hazardous stations on automated production lines
سيناريوهات التطبيق
Single hazardous motion control: Single stroke, shearing, or mold closing only when both buttons are pressed together.
Safety interlock protection: Prevents hands from entering dies, blades, or press zones during machine operation.
Manual loading/unloading stations: Machine starts only after the operator removes hands from hazardous areas.
Semi-automatic stations: Without full safety guard doors, relying on operator discipline.
Industry Applications
Automotive stamping and sheet metal processing
Hardware forming for home appliances
Plastic housing injection molding
Hardware tools and fastener manufacturing
Wood furniture pressing and assembly
