ZZWPE electronically controlled temperature control valve Features

This series of products nominal diameter from 20 to 200mm, nominal pressure has 1.0,1.6,4.0,6.4MPa, temperature range from -20 ℃ ~ 350 ℃, the signal is 0 ~ 10mA.DC accept or 4 ~ 20mA.DC to change medium flow is adjusted so that the controlled process parameters maintained at a given value, which is suitable for single-seat control pressure is small, medium viscosity or slightly larger particle impurities occasions. Sleeve pressure regulator is suitable for larger occasions
