Overview

ZDLS electronic electric high-pressure angle control valve consists of a PS series or 3610 series linear-motion electric actuator and a low-flow-resistance angle-type single-seat valve body. The electric actuator is an electronically integrated unit with a built-in servo amplifier. Once the control signal (4-20 mA DC or 1-5 V DC) and power supply are connected, the valve opening can be regulated to adjust process parameters such as pressure, flow rate, liquid level and temperature. It features fast response, simple wiring, large flow capacity, compact size and high regulating accuracy. The angle-type high-pressure control valve was developed to address the serious problems of short service life, easy fracture of the valve stem and easy detachment of the bushing under severe working conditions of high pressure or high differential pressure with serious cavitation and erosion. It employs multi-stage throttling to distribute the differential pressure, reducing cavitation, erosion and turbulence damage, and greatly improving the service life of the control valve. In urea systems in particular, its service life is 2-3 times longer than that of ordinary high-pressure valves. The valve body is of right-angle design with a single-guided plug. The flow path is simple with low resistance, making it especially suitable for regulating high-viscosity fluids and media containing suspended solids and particles, avoiding coking, sticking and clogging.
