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. -

Needle Type Globe Valve SHV6.4
Needle Type Globe Valve SHV6.4 is mainly applicable to EH oil control systems. The high-pressure oil supplied to the actuator flows through the stop valve to the servo valve to operate the hydraulic servomotor. The needle valve can control the full opening and full closing of the oil circuit, and can also throttle by adjusting the opening of the cone valve. It is mainly composed of a valve rod, a body, a cushion block, a retaining ring, an O-ring, a cone core, and a cover nut.

mechanical trip isolation valve F3DG5S2-062A-220AC-50DFZK-VB-08
The mechanical trip isolation valve F3DG5S2-062A-220AC-50DFZK-VB-08, also called mechanical trip solenoid valve, is used to isolate the fluid. In short, it is a switch. The isolation valve belongs to the on-off valve, which is only in the open or closed state. Unlike the on-off valve, it basically has a requirement for the leakage level. Relatively speaking, the requirements for safety are higher than those for on-off valves, and some parts also have higher requirements for opening and closing speed. It should be said that it is a valve that emphasizes fluid separation on both sides and higher safety. -
977HP sealing oil differential pressure valve
The 977HP differential pressure regulating valve is used in the sealing oil system of the generator set by comparing the sum of hydrogen pressure and spring pressure with the oil pressure. When there is a pressure difference, the valve stem moves up and down, which affects the opening of the valve port and makes The flow and pressure at the outlet of the differential pressure valve change accordingly, and the pressure balance is finally achieved. At this time, the pressure difference ΔP between hydrogen pressure and oil pressure is relatively constant, and the pressure difference value ΔP can be adjusted by adjusting the spring. The differential pressure adjustment range of this valve is 0.4~1.4bar. -
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 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. -

23D-63B steam turbine turning solenoid valve
Turning solenoid valve 23D-63B is designed for turbine steering control. Turning gear is a driving device that drives the shaft system to rotate before and after the steam turbine generator unit is started and stopped. The turning gear is installed on the rear bearing box cover between the turbine and the generator. When it is necessary to rotate, first pull out the safety pin, push the handle and hand turn the motor coupling until the meshing gear is fully meshed with the rotating gear. When the handle is pushed to the working position, the contact of the travel switch is closed and the steering power supply is connected. After the motor is started at full speed, it drives the turbine rotor to rotate. -
