Pressure sequence valve UZKB 6 NS 6 NG 6 Pressure sequence valve type UZKB 6 serves to control pressure in hydraulic systems. It can be well used as a direct operated pressure relief valve. OPERATION DESCRIPTION Spring force is adjusted by turning the handwheel ( 6 ) of the setting element. If control pressure overcomes the resistance of the spring ( 3 ), the control spool ( 2 ) moves and opens the connection P to P1. The spool ( 2 ) in the housing ( 1 ) is pressure-loaded from port P and from opposite side spring ( 3 ) - loaded in relation to the spring deflection. TECHNICAL DATA Hydraulic fluid Mineral oil, phosphate ester Adjustable sequence pressure ( at T = 0 MPa) Nominal fluid viscosity Viscosity range Optimum working temperature ( fluid in a tank ) Fluid temperature range Required filtration Recommended filtration
