Product Name:
Z641H-16C pneumatic valve
Description:

Z641H-16C气动闸阀

【 产品概述 】

     新系列活塞式气动闸阀(以下简称闸阀),由于具有优良的切断性能,故在工业领域得到广泛应用。公称压力有1.6、6.4MPa,口径由40至600mm,温度范围为-196℃至500℃。

【 特点 】
      ● 闸阀的执行机构具有正、反两种作用功能,故阀的开、关方式有气开、气关两种作用方式。闸阀采用金属接触式独特结构、动作可靠,具有极高的切断性能,比常规的切断阀优越。允许泄漏量达到10-8×KV。 使用范围广,温度可由-196℃至500℃,口径小至40mm,大至600mm. 阀座有平行、60°V型切口和90°V型切口三种,适应不同使用场合需要。 ● 阀体可用夹套形式保温,用以介质冷却后易堵塞,凝结或结焦场合使用。
