Product Description

ZDLM electronic electric sleeve regulating valve is composed of 3810L type (or P-SL series) straight travel electronic electric actuator and fine small sleeve valve. Contains the feeding function, accepts the unified 4-20mA or 1-5V·DC standard signal, converts the current signal into the corresponding linear displacement, automatically controls the opening of the regulating valve, and achieves the continuous adjustment of the process parameters such as pressure, flow, temperature and liquid level of the fluid in the pipeline.
First, ZDLM electric sleeve control valve overview
ZDLM electric sleeve regulating valve is composed of PS series or 3610 series direct travel electric actuator and low flow resistance through single-seat valve. (can also be matched with other brands of direct travel actuator).
The electric actuator is an electronic integrated structure, with servo amplifier, input control signal (4-20mADC or 1-5VDC) and power supply to control the opening of the regulating valve, to achieve the adjustment of pressure, flow, liquid level, temperature and other working parameters. With sensitive action, simple connection, large flow, small size, high adjustment accuracy special ZDLM point. The control accuracy and performance are significantly improved than DKZ type.
The spool of electric sleeve regulating valve is fluid pressure balance spool. The valve spool of the electric single-seat regulating valve is the fluid pressure unbalanced spool, so the electric sleeve regulating valve is more suitable for the occasion of large pressure difference. In some cases, it can replace the electric single-seat regulating valve
Second, ZDLM electric sleeve regulating valve application
ZDLM sleeve regulating valve has the characteristics of good stability, not easy to produce vibration, low noise, sensitive to temperature, etc. Single sealed electronic electric sleeve regulating valve is suitable for clean media with strict leakage requirements and small pressure difference. Double sealed electronic electric sleeve regulating valve is suitable for clean media where leakage requirements are not strict and pressure difference is large. Orifice throttle type, can be used as a low noise valve. Electronic electric sleeve regulating valve is widely used in electric power, metallurgy, chemical industry, petroleum, environmental protection, light industry, equipment and other industries.

4 Allow differential pressure
The standard assembly of the electric sleeve regulating valve allows a large pressure difference, but considering the noise and vibration caused by the erosion of the medium fluid on the valve plug and sleeve and the high pressure difference, so when the pressure difference of the valve exceeds 3MPa: the corresponding process measures should be taken.
