  • Electro-hydraulic servo valve G761-3034B

    Electro-hydraulic servo valve G761-3034B

    G761-3034B Electro-hydraulic servo valve is an actuator that converts electrical signal input into high-power pressure or flow pressure signal output. It is an electro-hydraulic conversion and power amplification component that can convert small electrical signals into large hydraulic power, driving various types of loads. This series of electro-hydraulic servo valves can be used as three-way and four-way throttle flow control valves, with fast response, pollution, and other characteristics, suitable for position, velocity, force (or pressure) co servo control systems.

  • Flow Control Servo Valve 072-1202-10

    Flow Control Servo Valve 072-1202-10

    Flow Control Servo Valve 072-1202-10 is mainly used for high pressure regulating valve of main machine in power plant, intermediate pressure regulating valve of main steam valve, main steam valve and other parts. When changing oil in the system, the servo valve should be thoroughly cleaned of the oil tank before injecting new oil, and replaced with a flushing plate. After passing through 5~10 μ The m oil filter fills the oil tank with new oil. Start the oil source, flush for more than 24 hours, then replace or clean the filter, and complete the re cleaning of the pipeline and oil tank. If the servo valve is blocked during use, users who do not have the necessary conditions are not allowed to disassemble the servo valve without authorization. Users can replace the filter according to the instructions. If the fault cannot be eliminated, it should be returned to the production unit for repair, troubleshooting, and adjustment.

  • Steam Turbine EH Oil System Servo Valve 072-559A

    Steam Turbine EH Oil System Servo Valve 072-559A

    The electrohydraulic servo valve 072-559A is an important component of the hydraulic servo system. It is a hydraulic control valve that continuously controls flow and pressure in proportion by changing input signals. The minimum flow size of the nozzle valve is about 0.2 mm, while the minimum flow size of the nozzle baffle servo valve is 0.025~0.10 mm. Therefore, the nozzle has strong anti-pollution ability, high reliability, and long service life. The anti-pollution ability of servo valves is generally determined by the minimum flow rate in their structure. However, in multistage servo valves, the minimum size in the front stage oil circuit becomes the decisive factor.

  • G761-3033B DEH system electro-hydraulic servo valve

    G761-3033B DEH system electro-hydraulic servo valve

    G761-3033B DEH system electro-hydraulic servo valve outputs the modulated flow and pressure after receiving the electrical analog signal. It is not only an electro-hydraulic conversion element, but also a power amplification element. It can convert the weak electrical input signal of low power into the output of high-power hydraulic energy (flow and pressure). In the electro-hydraulic servo system, it connects the electrical part with the hydraulic part to realize the conversion of electro-hydraulic signal and hydraulic amplification. Electro-hydraulic servo valve is the core of electro-hydraulic servo system control.

  • SM4-20(15)57-80/40-10-S182 actuator electro-hydraulic servo valve

    SM4-20(15)57-80/40-10-S182 actuator electro-hydraulic servo valve

    SM4-20(15)57-80/40-10-S182 actuator electro-hydraulic servo valve can provide system closed loop control with exact positional accuracy, repeatable velocity profles, and predictable force or torque regulation.
    Typical applications include plastic injection molding and blow molding systems, test and simulation equipment, die casting machines, hydraulic press brakes, animation and entertainment equipment, oil exploration vehicles, and lumber machinery.
    This model of the high performance SM4 series offers a wide range of rated flows from 3,8 to 76 l/min (1.0 to 20 USgpm) at ∆p of 70 bar (1000 psi).

    The SM4 is a two-stage, modular design, flow control valve which can be manifold or subplate mounted. The symmetrical, dual coil, quad air gap torque motor is integrally mounted to the frst stage nozzle flapper pilot valve with six screws. The second stage utilizes a four-way sliding spool and sleeve arrangement with a mechanical null adjust. Spool position is fed back to the frst stage by means of a cantilever spring. An integral 35 micron (absolute) flter reduces sensitivity to contamination of the frst stage.
