ZZY型自力式压力调节阀无需外加能源,利用被调介质自身能量为动力源,引入执行机构控制阀芯位置,改变两端的压差和流量,使阀前(或阀后)压力稳定。具有动作灵敏,密封性好,压力设定点波动小等优点,广泛应用于气体、液体及蒸汽介质减压稳压或泄压稳压的自动控制。本系列产品有单座(ZZYP)、套筒(ZZYM)、双座(ZZYN)三种结构:执行机构有薄膜式、活塞式二种:作用型式有减压用阀后压力调节(B型)和泄压用阀前压力调节(K型)。产品公称压力等级有PN16、40、64;阀体口径范围DN20~300;泄漏量等级有II级、IV级和VI能三档;流量特性为快开;压力分段调节从15~250MPa。可按需要组合满足用户工况要求。
