1、 Overview of Electric High Voltage Regulating Valve Products
The electric high-pressure regulating valve of Shanghai Yuhu Company consists of a PSL series or 3810L series linear electric actuator and a high-pressure regulating valve body. Electric high-pressure cage type regulating valve is a product developed to address the serious problems of short service life, valve stem breakage, and liner detachment of regulating valves under harsh working conditions such as high pressure or high pressure difference, severe cavitation and erosion. The electric high-pressure regulating valve adopts a cage type throttling form to share the pressure difference, reducing cavitation, erosion, and flow damage, greatly improving the service life of the regulating valve, especially when used in urea systems, which is 2-3 times longer than ordinary high-pressure valves. The electric actuator is an integrated structure with a servo amplifier inside. By inputting control signals (4-20mADC or 1-5VDC) and power supply, the valve opening can be controlled to adjust working parameters such as pressure, flow rate, liquid level, and temperature. The valve body is a straight through type, and the valve core is a single guide structure. The valve body has a simple flow path and low resistance. The electric high-pressure regulating valve is particularly suitable for regulating high viscosity fluids containing suspended solids and granular media, which can avoid coking, bonding, and blockage. The electric high-pressure regulating valve as a whole has the characteristics of sensitive action, simple connection, large flow rate, small volume, and high regulation accuracy.
