PRODUCT OPERATION

The unit has 3 ports marked IN, OUT and SIG- Actuator operating pressure is connected to IN port and OUT port is connected to actuator. SIG Port is connected to line pressure. The supply Pressure connected to SIG Port is sensed by a spring loaded upper diaphragm, subassembly causing closing of exhaust port and opening of pilot valve. The output form the pilot valve acts on lower diaphragm and the thrust developed by it acts upon a piston, which opens ,main valve and allows air to the actuator. Reduction of supply pressure causes downward movement of upper diaphragm subassembly, resulting in reduction of pressure above lower diaphragm. The piston move upwards and the valve is closed to block this air in the actuator
