Guida alla selezione del modello

By Port Size

Asian market: C06 (ø6 mm) raccomandato

Mercato nordamericano: C07 (ø1/4″) raccomandato

By Installation

Per installazione fissa: select models with suffix B (including bracket)

For temporary installation or limited space: standard models without B

Note sulla sicurezza

Output is enabled only when both buttons are pressed simultaneously within 0.5 secondi.

Operating pressure must be 0.25–1 MPa; sotto 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.
