Operation Figure 2 shows the normally open valve in the open or full flow position and the normally closed valve in the closed, or zero flow position. The actuator spring provides the necessary force to hold the stem in the raised or normal position. In the event of power failure, a spring return actuator returns the valve to its normal position. Non-spring return actuators will hold the last commanded position. Normally Open Normally Closed Figure 2. Operation. 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 may initiate cycling, and the seat and throttling plug may be damaged because of the restricted opening. Correct sizing of the control valve for actual expected conditions is considered essential for good control. Some variables which must be determined are: The water and 50% water-glycol solutions, are the controlled mediums. The pressure differential that will exist across the valve under maximum load demand. The maximum capacity the valve must deliver. The maximum line pressure differential that the valve actuator must close against. See Tables 2 through 3, and Figure 1 for valve capacities and sizing selection. 6/10 High Pressure 2-way 2 1/2-6 Globe Valves
