Flowrite VF 599 Series Two-Way Valves 2-1/2 to 6-inch Flanged Iron Body VF 599-1 VF114R1 VF115R1 Description Features Application The Flowrite VF 599 series two-way valves are designed to work with either a pneumatic or electronic actuator. They are available in both ANSI Class 125 and 25 for normally closed or normally open action. Valve flange face-to-face dimensions meet ISA 75.3 standards Direct coupled universal bonnet Two flow characteristics (equal percentage or linear) Choice of bronze or stainless steel trim ANSI Leakage Class IV (.1% of Cv) Cartridge type packing These Flowrite valves are generally recommended for water, steam, and glycol solutions to 5%. Product Numbers See Tables 1 and 2. Water inlet pressures up to ANSI 125 and ANSI 25 cast iron body rating Water modulating differential pressure up to 25 psi (172 kpa) for bronze trim and 5 psi (345 kpa) for stainless steel trim Steam inlet to psig and modulating differential pressure up to 5 psi (345 kpa) Ordering a Valve Plus Actuator Assembly To order a complete valve plus actuator assembly from the factory, combine the actuator prefix code with the suffix of the valve assembly product number. See 155-34P25 (TB 249) for selection procedure and ordering codes. Valve assemblies can be ordered using the numbers in Tables 1 and 2.

2-1/2 to 6-inch Flanged Iron Body Operation Figure 4 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. See the of the various actuators for additional information. VF118R1 Normally Open Figure 4. Operation. Normally Closed 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 medium to be controlled: steam, water, etc. The maximum inlet temperature and pressure of the medium at the valve. 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 AB-1 Control Valve Selection and Sizing (Document Number 155-285) for further recommendations. See Tables 4 through 7 for valve capacities. Installation Install the valve so that the flow follows the direction of the arrow indicated on the valve body identification tag. For best performance, install the valve assembly with the actuator above the valve body. The valve and actuator can be installed in any position between vertical and horizontal. It is not recommend to install the valve assembly below horizontal or upside down. For flange dimensions and bolt hole information, see 155-33P25 (TB 248). Allow sufficient space for servicing the valve and actuator. See Table 14 for valve body dimensions. See Figure 7 and Table 13 for dimensions of the service envelope recommended around the actuator. NOTE: Instructions for field mounting an actuator, spring adjustments, wiring diagrams, and start-up are covered in the and Installation Instructions for each actuator. Page 8
