ZDLM Electric Sleeve Type Pressure Balanced Control Valve

Brief Introduction

ZDLM Electric Actuated Sleeve Type Pressure Balanced Control Valve adopt Pressure Balanced Sleeve-guided structure. It has following advantages: Precise valve body , S-Pattern Flow Port, Small Pressure Drop, Big Adjusting Range and High Precisi on of Flow Cv Value. The Dis-guiding area is big. It also has strong aseismic performance. The seali ng performance is conformed to Standard GB/T4213-92.

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