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.

Steam turbine Shutoff valve HF02-02-01Y

The HF02-02-01Y shut-off valve is mainly used as the actuator of the EH oil control system, suitable for 660MW and below units. It is mainly used to quickly cut off the oil inlet of the hydraulic servomotor during load shedding or trip conditions, to avoid a decrease in system oil pressure due to the transient oil consumption caused by the quick closing of the hydraulic servomotor. The actuator control type, also known as servo type, can control the steam valve at any intermediate position and proportionally adjust the inlet steam volume to meet the needs. It is composed of hydraulic motor, linear displacement sensor, shut-off valve, quick closing solenoid valve, servo valve, unloading valve, filter component, etc.

Stainless Steel Bellows Globe Valve WJ40F-1.6P

The stainless steel bellows globe valve WJ40F-1.6P is generally used on pipelines with high sealing requirements. For example, for highly hazardous liquid pipelines, such as chlorine, hydrogen, ammonia, and other media, the double sealing of valve cover packing combined with corrugated pipes is used to avoid leakage of high-risk media and cause safety production accidents. This bellows globe valve is often used in power plants, nuclear power plants, etc. In situations where radiation leakage must be prevented at all times, bellows sealed valves are the ultimate choice. In addition, some pipelines transporting expensive liquids can also use bellows globe valves to ensure zero leakage of the medium and avoid huge losses caused by leakage.

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

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.
