Technical Instructions Document No. 155-320P25 March 11, 2019 Operation 2-Way 599 Zone Valve Series: Two-Way and Three-Way Figure 3 shows the zone valve in the open or full flow position. The valve spring provides the necessary force to hold the stem in the raised or NO position. In the event of power failure, the actuator returns to its normal position; the actuator determines whether the valve will fail open or closed. See the actuator Technical Instructions for additional information. Figure 3.

Allowable Differential Pressure in Relation to the System Pressure. Sizing The sizing of a valve is important for correct system operation. An undersized valve will not have sufficient capacity at maximum load. An oversized valve can initiate cycling and can damage the seat and throttling plug because of the restricted opening.
