ZAZS electric angle type high pressure regulating valve, the DDZ straight travel electric actuator two part and angle type valve. Based on a single 220V AC power source for power, receive 0 to 10 or mA or 4 ~ 20mA DC signal, automatic control valve opening, continuous regulation of pipeline fluid pressure, flow, temperature, level and other parameters.
Angle valve has the advantages of small volume, light weight, valve driven by the top structure, has the characteristics of flow path is simple, small resistance, easy to wash.
Suitable for the right angle connection, medium for the regulation of high viscosity, suspended solids and granular medium.
