ZZYP self-pressure regulating valve Overview
Self-pressure regulating valve without external energy is transferred medium itself pressure changes automatically adjust the function, with small pressure fluctuations saving energy and other characteristics, ZZYP self-pressure regulating valve pressure levels have PN1.6 \ 4.0 \ 6.4 \ 10.0mpa , the valve diameter range DN15-350mm available, temperature range -20 ° c - 560 ° c, so self-regulating valve is one of the most energy-saving pressure regulating valve products. Set of pressure within a certain range may also be adjusted according to demand.
Various processes needed occasions Self-pressure regulating valve has three valve cover types: normal (general case), the long-necked (pressure adjustment range), heat (temperature 350 ~ 550 ℃). There are three actuator types: diaphragm (diaphragm and enhanced common diaphragm), a piston, a metal diaphragm (bellows).
ZZYP Self-regulating valve model significance
