REXROTH Hydraulic pilot Relief Valve DB10-50 / 315 Speed Regulating Valve DB30 / DB20-1-50 / 200 / 100 / 50

Rexroth Pressure Relief Valve,Pilot-operated Type DB10 DB20 DB30

The following is the Huade hydraulic pilot relief valve DB10-50 / 315 and speed regulating valves DB30, DB20-1-50 / 200 / 100 / 50: Pilot relief valve DB10-50 / 315 - Model meaning: DB refers to the pilot relief valve, 10 represents the size of 10mm, 50 means the connection mode is plate, 315 means the set pressure is 31.5MPa. - Structural features: It consists of a main valve with a main core component and a conduit with a pressure setting component. The control pressure of oil road A acts on the main valve core, and the control oil road through a throttle hole acts on both the spring load side of the main valve and the ball valve core of the lead valve. When the oil road A pressure exceeds the spring set value, the lead valve core opens to achieve overflow. - Performance parameters: the specification is 10 hours, the flow rate is 250 L / min, the setting pressure is 5.0MPa, 10.0MPa, 20.0MPa, 31.5MPa, 35.0MPa five, the maximum working pressure is 31.5MPa. Application: It is widely used in hydraulic system of lifting, construction machinery, mobile work shop, machine tool, ship, metallurgy and so on. It is used to limit system pressure and protect system safety. Speed regulating valve DB30, DB20-1-50 / 200 / 100 / 50 Model meaning: DB means speed regulating valve, 30,20 means size, 1 may mean series number, 50,200,100,50 means different pressure grade or flow specification, etc. Features: The speed regulating valve is composed of pressure reducing valve and throttle valve in series. It can adjust the opening of pressure reducing valve dynamically and compensate the variation of pressure difference before and after throttle valve automatically. The flow rate range is different according to different specifications. For example, the flow rate of the speed regulating valve with diameter of DB20 may be about 500L / min. - Application areas: Hydraulic circuits suitable for machine tool induction systems, walking mechanisms for construction machinery, assembly devices for injection moulding machines, etc., which have high requirements for motion smoothness, can accurately control the motion speed of the execution element
