    4WREE6E32-2X/G24K31/A1V-655Rexroth proportional valve electro-hydraulic proportional valve referred to as proportional valve. Common hydraulic valve can only be adjusted by the way of pre-flow pressure, flow control set value. However, when the equipment mechanism requires adjustment or continuous control of the pressure and flow parameters of the hydraulic system during work, for example. It is required that the workbench can be fed at slow, fast and slow continuous speed, or simulate a certain control curve to achieve travel force control according to a certain accuracy. Ordinary hydraulic valves are not realized. At this time, the hydraulic system can be controlled by electro-hydraulic proportional valve.

    Rexroth proportional valve0811404033, German RexrothREXROTHbrand spare parts, brand new*products, quality assurance, stock, price advantage supply;
    Valve flow control can be divided into two types:
    One is switch control: either fully open, or fully closed, flow is either * large, or * small, there is no intermediate state, such as ordinary solenoid valve, solenoid valve, electro-hydraulic valve.
    The other is continuous control: the valve port can be opened according to the need for any degree of opening, thereby controlling the size of the flow, such as manual control of the valve, such as throttle valve, there are also electronically controlled, such as proportional valve, servo valve.
    Therefore, the purpose of using proportional valve or servo valve is to realize throttle control of flow in an electronically controlled manner (of course, pressure control can also be realized through structural changes), since it is throttle control, there must be energy loss, servo valve and other valves are different, its energy loss is greater, because it needs a certain flow to maintain the work of the pre-stage control circuit.
     
    Rexroth proportional valveconstant flow valve and constant flow control valve is different:
    1, constant flow valve only one valve flap, by this valve flap directly before and after the differential pressure of the valve, the implementation of the action to change the valve resistance, can become a“direct-acting variable resistance valve", it can not adjust the flow online, so the use of constant flow valve can not change the total flow of energy-saving operation, only seen in some central air conditioning systems.
    2, constant flow control valve is to compensate for the way when the resistance of the action, it has two valve clack, one is to adjust the valve clack, used to compensate for the differential pressure before and after the orifice, so it can become a“compensated variable resistance control valve"Its principle is: the use of the differential pressure before and after the orifice, as a driving force to compensate for the action, compensate and maintain the stability of the differential pressure before and after the orifice, so as to maintain the flow constant, adjust the size of the orifice can obtain different flow. Therefore, it can regulate the flow rate. It can also keep the flow constant when the system hydraulic conditions change. In the system, it can not only keep the flow of each branch constant, but also change and adjust the flow of each branch at any time to achieve dynamic balance. If the flow regulation is carried out twice a year from early cold to severe cold and from severe cold to late cold, the energy-saving operation mode of changing“the quality regulation of flow in stages can"be realized. The adjustment of constant flow control valve is simple and convenient, but for larger systems, twice a year adjustment is still a burden, and the price of constant flow control valve is high, although it can be recovered in the same year, but there is still greater psychological pressure on users.
