Jordan MK60 Sliding Gate Pressure Regulator is used to regulate the downstream pressure to a predetermined set point. The spring in the Mark 60 holds the sliding gate seats in their normally open position to allow the process media to pass through the seats. The downstream pressure is sensed beneath the diaphragm. As the downstream pressure exceeds the set point, pressure is exerted on the diaphragm which raises the stem to modulate the disc toward the closed position. As the seats close, downstream pressure will be reduced to the required set point. A decrease in pressure relaxes the spring and diaphragm to move the seats toward the open position.
