Quality is everything! US Walker (WORK) imported electric sleeve valve is composed of electronic electric actuators and low flow resistance through single seat adjustment mechanism. Within the servo actuator system without reprovision servo amplifier with an input signal and the power to control the operation, simple connection, the body is through single seat without cover oriented structure, the spool of a plunger-type structure, with small size, light weight, high traffic, high precision adjustment for flow, leakage demanding applications. Imported electric sleeve valve Features: interchangeability, use a large pressure difference. Depth dynamic servo amplifier uses negative feedback, can improve the accuracy of automatic adjustment. Body according to the design principles of fluid mechanics and other low flow resistance flow channel cross section, the rated flow coefficient increases 30%. Adjustable range, inherent adjustable ratio of 50, there is a percentage flow characteristic lines and the like. Electric sleeve valve spool is provided on the bottom of the pressure equalizing hole, a small unbalanced force, the valve stability, adjust the cut-off sleeves with soft seal structure spool up to Class VI leakage standards (zero leakage). Bellows seal type valve stem for moving form a complete seal, blocking absolutely fluid leakage. Electric operation takes many forms, suitable for 4 ~ 20mA.DC or 0 ~ 10mA.DC. E-electric control valve can directly control the valve opening by the current signals, no servo amplifier. When ordering, please provide the following information:? A nominal diameter (mm), nominal pressure (MPa), operating temperature range of two straight and before the pressure regulating valve, the valve pressure of 3 media name and status at 4 single seat??? valve supply voltage (220V or 380V, default 220V) 5 Input signal:??? 4-20mA, or 1-5V (default 4-20mA) 6 single-seat control valve body, the trim material requirements seven other special requirements (eg corrosion requirements, proof grade requirements, leakage class limits, etc.) USA Walker (WORK) imported electric sleeve valve Chinese agents welcome your inquire and order!
