Mark 50 Self-Operated Back Pressure Regulators The Mark 50 Sliding Gate Back Pressure Regulator is used to regulate upstream pressure at a predetermined setpoint. The spring in the Mark 50 holds the sliding gate seats in their normally closed position.
The upstream pressure is sensed beneath the diaphragm. As the upstream pressure exceeds the setpoint, pressure is exerted on the diaphragm which raises the stem to modulate the disc (the movable component of the sliding gate seat set) toward the open
position. As the seats open, upstream pressure will be regulated to the required setpoint. A decrease in pressure relaxes the spring and diaphragm to move the seats toward the closed position. The actuator required for the valve will be decided by the diaphragm material.

Mark 501/502 High Flow Back Pressure Regulators The Mark 501 and 502 meet higher capacity requirements than standard back pressure regulators. The High Flow Mark 501 has Cv’s as high as 50 (43Kv) and the Super High Flow Mark 502 has Cv’s up to 70 (60.2 Kv). Each valve is standard with Jordan’s Sliding Gate Seats, which helps to reduce the build-up commonly associated with high flow back pressure regulators.The actuator required for the valve will be decided by the diaphragm material.
