Senses pressure in a circuit and may be used to start or shut down a system. A pressure switch can be used to remove the cutting tool and turn off machine in the event of loss of clamping pressure. Pressure Switch With adjustable opening pressure, this valve may be used to control the sequence of work devices in a common circuit. Sequence Valve Pilot Operated Check Valve A two-way valve used to lock pressure in a working circuit. Automatic free return flow is provided via air pilot operation. Designed so that loss of shop air line pressure will have no effect on the hydraulic circuit in booster applications.
