Hydraulic solenoid valve model

Hydraulic solenoid valve model Regarding the hydraulic solenoid valve model, different manufacturers have different arrangements for models, and here is small to give an example of the syndrome of hydraulic solenoid valve. For example: 34BYM-L20H-T. Where 34 indicates that the 3-bit 4 pass, B is the AC type, Y is the hydrodynamic, and M is a split valve function, and the thread connection form, 20 is a nominal diameter, H is a nominal pressure, H is expressed as high pressure 31.5 MPa, T Indicates the spring to medium code. WMM type manual replacement valve The manual replacement valve is a directional control valve manipulating using a manual lever. The valve is different depending on the positioning method, there are two types of spring reset and steel ball positioning. Spring reset manual commutation valve, when the external force of the handle is canceled, the reset spring pushes the spool back to the initial position. The steel ball positioning is when the external force of the handle is canceled, the spool relies on the steel ball positioning in the commutation position. 2FRM type speed control valve The 2FRM type regulator valve is a flow control valve of a two-way, which is configured in series by a pressure reducing valve and a throttle valve. Since the pressure reducing valve is pressure compensated, the flow rate of the speed regulator is not loaded The impact of changes is maintained. At the same time, the throttle window is designed to be thin blade, and the flow rate is small in temperature. When the valve valve is parallel to the one-way valve, the oil flow can reflow in reverse. Direct relief valve The DBD type straight relief valve is used to prevent system overload and maintain system pressure constant. Structural principle: The pressure oil of the oil port acts at the bottom of the damping piston, forming a patch pressure against the spring force. When the submerged pressure is less than the spring force of the regulating spring, The taper valve is closed, and this valve does not affect the regulation. With the continuous improvement of the inlet pressure. When the liquid pressure is greater than the spring force, the tapered valve is opened, the excess oil spills the fuel tank, so that the oil port pressure is stabilized on the modulation value. Sequential valve DZ-3X Pilot Sequence Valve: The valve utilizes the oil circuit itself to control the sequence of operation of the hydraulic cylinder or motor to achieve automatic control of the oil line system. Change the connection method of controlling oil and drain, which can also be used as a unloading valve and a back pressure valve. SV / SL type liquid control one-way valve The liquid-controlled one-way valve is widely used, such as using the locking circuit of the hydraulic one-way valve, prevents the self-weight drop, the filling valve loop, the bypass discharge valve loop, the accumulator oil supply circuit, etc. Read more
