Application
The CV632 Sliding Gate Pressure Regulator is used to regulate the downstream pressure to a predetermined setpoint. The spring in the CV632holds the sliding gate seats in their normally open position to block 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. The actuator required for the valve will be decided by the diaphragm material. This series is designed primarily for high pressure steam service as commonly found in power plants, refineries, pulp & paper mills, and other high pressure process applications. The structures for this series are bellow balancing, double-core balancing and disc guide balancing with pressure balancing core.
