PRODUCT OPERATION

It is a spring and diaphragm operated equipment. Line pressure is connected to signal port. Control instrument pressure is connected to "IN" port and OUT" port is connected to actuator. The signal pressure causes upward movement of diaphragm sub assembly against the adjusting spring. The valve coupled to the diaphragm, opens and allows flow of air to actuator. When the pressure drops below the set value the spring force exceeds the diaphragm pressure and closes the valve thereby blocking the air path. When the air pressure is restored to set value the valve opens automatically.
