Self-Operated Pressure Regulators

The MK60 Sliding Gate Pressure Regulator is used to regulate the downstream pressure to a predetermined setpoint.  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 setpoint, pressure is exerted on the diaphragm which raises the stem to modulate the disc (the moveable component on the sliding gate seat set) toward the closed position.  As the seats close, downstream pressure will be reduced to the required setpoint.  A decrease in pressure relaxes the spring and diaphragm to move the seats toward the open position.
