ZZWPE self-operated electric temperature control regulating valve

A brief introduction of self controlled temperature control valve ZZWPE type

Self-controlled temperature control valve (suitable for large caliber and thermal oil control), the biggest feature of the valve is only ordinary 220V power supply, the use of the medium's own energy, directly to steam, hot gas, hot oil and gas and other media temperature automatic regulation and control, can also be used to prevent overheating or heat exchange

Self-operated electronic control temperature regulating valve ZZWPE type details

Product name:

ZZWPE temperature self-reliant [electronic type] regulating valve

Product Introduction

Self-controlled temperature control valve (suitable for large caliber and thermal oil control), the biggest feature of the valve is only ordinary 220V power supply, using the energy of the medium to be adjusted directly to the temperature of steam, hot gas, hot oil and gas and other media to automatically adjust and control, Can also be used in the prevention of overheating or heat exchange occasions, the valve structure is simple, easy to operate, choose a wide range of temperature control, response time, reliable sealing performance, and can be adjusted at will in the operation, so widely used in chemical, petroleum, food, textile, hotels and restaurants and other departments of hot water supply

Product Features

The nominal diameter of this series of products is from 20 to 200mm, the nominal pressure is 1.0, 1.6, 4.0, 6.4MPa, the temperature range is from -20ºC~350ºC, the received signal is 0~10mA.DC or 4~20mA.DC to change the flow rate of the modulated medium, so that the controlled process parameters remain at the given value. The single-seat adjustment type is suitable for small pressure difference, large medium viscosity or slight particle impurity occasions. Sleeve regulating type is suitable for large pressure difference occasions
