Measure the flow rate on the partner valve. If you have an excess reduce the flow rate on the partner valve. Record the flow rate in the commissioned condition Turn the spring setting mechanism on the valve until the calculated opening pressure loss is set If the valve is open turn the mechanism until it is just closed.

Flo Trol Flow Control and Flow Regulator Valves. The Flomatic Flo Trol automatic flow control valves are designed to give constant flow over a wide pressure range.. The valve design has no moving part rather a self cleaning flexible orifice that varies in size with applied pressure so that a constant flow rate is maintained.
Downstream pressure fluctuations are counterbalanced by the internal regulating valve to maintain the SCFM to within 1 1/2 of the flow setting. Variations in upstream pressure and temperature should be minimized due to the compressibility of gases and the corresponding changes in density.
Aug 26 2021 Control Valves. Control valves are a common element in the process and manufacturing industry. They control the fluid flow in the attached network. The fluid goes into one side of the valve its flow is adjusted and comes out the other side. The fluid flow can be controlled by manual or automatic mechanisms and comes in various shapes sizes and
As a leader in hydronic balancing Flow Design offers a complete line of automatic balancing valves. All Flow Design regulators are precision machined and precisely assembled in a process that includes continuous flow testing to eliminate errors. Model AC 1/2″ 2″ AutoFlow regulator/ball valve/Port section/Union. Directional flow/Dual access ports. SWT or FPT
With automatic flow regulators the terminal units will not exceed design flow even after modifications or additions to the system. In a proportionally manually balanced system such changes can cause overflow unless adjustments are made at risers branches and terminals.
An automatic flow rate control valve includes a tubular body defining a flow path between inlet apertures having a gradually variable cross sectional area and a fluid outlet at one end a flow control piston is axially movable within the tubular body under opposite actions of the fluid pressure and a biasing spring to choke the fluid inlet apertures while maintaining a constant
An IV fluid flow control device includes a rigid casing defining a flow passage having a fluid entrance and a fluid exit. A rigid previous base is affixed inside the flow passage of the casing. A flexible resilient flow regulator is disposed inside the flow passage of the casing adjacent to and upstream of the base. The flow regulator normally has a smaller cross section than does the
AUTOMATIC FLOW CONTROL VALVE OVERVIEW The Ross Control Valve is to control flow into the tank via an Electronic Process Controller controller to be supplied by others . OPERATIONRATE OF FLOW CONTROL CONDITION When operating with the Process Controller the hydraulic controls are isolated by the 2 Way Solenoid Part No. 30.
Automatic Flow Regulator is used as a liquid control device for Ammonia Overfeed Systems. This Automatic Flow Regulator once set maintains a constant flow rate of liquid to the evaporator it also serves as a check valve to prevent back flow into the liquid line from the evaporator during pressure reversals such as occur during hot gas defrost.
Oct 21 1994 An automatic flow control valve for maintaining a predetermined output flow rate in response to a varying pressure differential across the valve has an orifice element an occluding element and a spring each placed at least partially within a valve housing.
