1 3-way flow control valve type UDUE10 NS10 up to 35 Ma up to 50 dm 3/min DT SHEET - OER RTION MNU NUL WK LICTION 3-way flow control valve type UDUE10 is intended for independent from pressure on supply side of (pump) setting flow rate in hydraulic system. It enables to control speed movement of receiver - mostly piston rod or hydraulic motor. Supply stream (port ) is divided on priority stream directed to port and residual discharged by port B to reservoir or supply other receiver. DESCRITION OF OERTION UDUE10-22/ B(Q B) (Q ) 5 (Q ) The principle of regulator operation is achieved by division of supply stream (port ) on priority stream directed to port and residual stream (port B). 3-way regulator type UDUE10 consists of two principal valves: throttle and differential. Throttle valve act as measuring and consists of choke (1) made in form of poppet valve and setting (2). Differential valve acts as regulator and consists of spool (3) and spring (4). Hydraulic fluid flowing through the valve from port to causes drop of pressure on choke (1), which depends on setting and current flow value through choke (1). ressure difference before and after choke (1) acts on spool (3) and after overcoming spring preload (4) causes opening the way from port to B enabling residual stream flow. Spool (3) gets position of balance at the moment when pressure drop on measuring throttle (1) is corresponding to spring preload (4). It means that stream value flowing through port is constant, independent from pressure on supply side (port ), and is dependent only on position of regulator setting. Regulator is equipped with check valve (5), enabling free flow from port to. Type UDUE WK

During the operation one must maintain the recommended fluid viscosity and provide proper filtration specified in this Data Sheet S - Operation Manual. 2. In order to ensure safe and failure-free free operation of the valve, the following must be checked: operation of the valve cleanliness of the hydraulic fluid 3. In order to provide proper tightness of the valve connection to a hydraulic system, one should ensure tightening torque and valve operation parameters as a s specified in this Data Sheet - Operation Manual. 4. person operating the valve must be familiarized with the content of this Data Sheet - Operation Manual.
