SMC

With this OSHA compliant Pressure Relief 3-Port Valve (Double Action) With Locking Holes, the supply and exhaust status of air flow can be checked at a glance.
[Features]
· The safety-measure manually operated valve can be used to prevent accidents caused by residual pressure in pneumatic lines.
· A specification in which when residual pressure is being released, the valve handle can be locked in position to prevent accidental operation.
· The double action type is structured so that the handle has to be pushed down before turning, helping prevent accidental operation.
