This reduces both cost and size by reducing the required number of hoses and fittings and allows for a more compact installation. The CV120 flow control utilises the design and components from the established VFD120 series. This results in good flow to pressure characteristics allowing a consistent flow independent of load pressure. The directional control element uses a hardened alloy steel spool with a number of control options and types available. The valve has two pump inlets and two tank outlets which allow the plumbing to be connected either from the side or top of the valve. It also features a full flow pilot operated relief valve which protects the A and B regulated ports. There is also an option available to have full inlet flow from the A port and regulated flow from the B port. This is useful when using one port to feed a track motor requiring full pump flow and a regulated port to control the speed of a second motor. It is also possible to connect valves in series using a HPCO coupling. Features • Clearly marked single- turn hand dial permits fast visual adjustments to predetermined ‘Priority’ flow • Pressure compensated permitting both ‘Priority’ and ‘By-Pass’ to be used simultaneously at varying pressures without affecting the ‘Priority’ flow rate • Easy installation allowing side or top connections • Bankable using a HPCO coupling & standard fittings If a HPCO (fitted to T1) is installed for the use of downstream valves, a second pressure relief valve is required to control the pressure out from the HPCO. In this instance the two relief valves work independent of each other. • Adjustable relief valve Specifications Maximum Operating Pressure: 250 bar (3600 psi) Total Flow Capacity: 120 lpm (32 USgpm) Regulated Flow Capacity: 0 - 95 lpm (0 - 25 USgpm) Porting: See table 4, ordering codes Material: Steel components in cast.
