ZDLP Electric Actuated Single Seat Globe Control Valve

Description

ZDLP Electric Actuated Single Seat Globe Control Valve

Brief Introduction


ZDLP Electric Actuated Single Seat Globe Control Valve adopt top-guided structure. It has following advantages: Precise valve body , S-Pattern Flow Port, Small Pressure Drop, Big Adjusting Range and High Precision of Flow Cv Value. The Dis-guiding area is big. It also has strong aseismic performance. The sealing performance is conformed to Standard GB/T4213-92.

Such control valve uses small, strong and high precision electric actuator with On-Off Function or with 4-20mA DC or 1-5V direct current signal to realize valve's proportional action, which is more suitable for the working condition required reliable and high sealing performance, High Temperature or Low temperature or High Pressure.
