VR51-C06 - 

When starting an operation, accidents such as fingers being caught can be prevented by requiring both hands to start these push button operated valves. In order to restart, remove both hands from the mechanical valve and then apply them again. Do not use the product with a pressure of under 0.25 MPa. The time lag for operating the VR51 is different depending on the operating pressure. The higher the operating pressure, the shorter the time lag, and vice versa. If used under 0.25 MPa, an output will be available; however, safety is not likely to be maintained, even though the time lag may exceed 0.5 seconds.
Features:

An Output Is Available Through Synchronized, Two-Hand Operation (Within 0.5 Sec)

The Output Air Will Stop Even if One Hand Is Removed During the Operation

The Pilot Pressure for an Air-Operated Valve Will Be Exhausted By An Integral Quick Exhaust Valve, Exhaust Conductance: 1 dm³/(S
