Main features of imported electric high pressure regulating valve:
1. the series of products adopt the complete disassembly and disassembly structure, with small operating force distance. The valve cavity parts (including valve seat, valve core, throttle assembly, seal, etc.) can be taken out of the parallel valve cavity. The maintenance is very convenient. The valve body does not need to be cut off from the pipe and can be used for a long time.
2. the valve core is a balanced structure of plunger body, with small operating force distance and high sensitivity.
3. the throttle assembly is composed of a perforated plate collector type throttle ring and a sleeve type throttle sleeve, and is equipped with a uniform flow cover. Therefore, it has the comprehensive characteristics of low flow high pressure difference, no cavitation, high flow and good regulation performance, and no noise in the flow discharge comb flow. It completely meets the requirements of the harsh working conditions such as high pressure difference, and effectively realizes the flow regulation control of high temperature and high pressure differential fluid, which has good adjustability and adjustment The accuracy of the section is high.
4. the throttle ring can realize multi-stage pressure reduction and throttling within 55% of the valve working stroke
5. the valve core and seat sealing surface are overlaid with titanium carbide, which is anti scour and corrosion resistant.

Description of inlet electric high pressure regulating valve:
The electric high pressure regulating valve imported by de lock lock in Germany is composed of PSL series or de lock series direct stroke electric actuator and high-pressure regulating valve body. Electric cage type high pressure regulating valve is a product developed for the control valve with short life, easy fracture of stem and serious problem of bushing falling off under the harsh condition of high pressure or high pressure difference, severe cavitation and erosion. The electric high pressure regulating valve adopts cage type throttle to share the pressure difference, which reduces the damage of cavitation, erosion and deflection flow, greatly improves the service life of the regulating valve, especially in urea system, which is 2-3 times longer than that of the ordinary high-pressure valve.
The electric actuator is an integrated structure, with servo amplifier. Input control signal (4-20madc or 1-5vdc) and power supply can control the valve opening, and achieve the adjustment of pressure, flow, liquid level, temperature and other working parameters. The valve body is straight through type, the valve core is single guiding structure, the valve body flow path is simple, the resistance is small, the electric high-pressure regulating valve is especially suitable for the high viscosity, containing the suspension and granular medium fluid adjustment, which can avoid coking, bonding and blocking. The electric high pressure regulating valve has the characteristics of sensitive action, simple connection, large flow, small volume and high precision.
