H400 程控阀 H400 Program-controlled Valves

H400程控阀由单座切断阀与气动活塞执行机构组成。切断阀阀芯采用上导结构，阀体结构紧凑，压降损失小，流量大。适用于两位式控制或需要紧急切断的场合，具有结构简单、操作方便、使用可靠、维修方便等特点。主要应用于无杂质、无颗粒的液体、气体介质，要求快速严密切断，快速放空的自动控制系统中。

The H400 program-controlled valveconsists of a single-seat shut-off valve and a pneumatic piston actuator.The shut-off valve employs a Plugwith an upper guide structure,and features a compact valve body,low pressure drop loss, andhighflowcapacity.Itissuitable for two-positioncontrolorscenariosrequiringemergencyshut-off,boastinga simple structure,convenient operation,reliableuse,and ease of maintenance.Thisvalve is primarily applied in automatic control systems for liquids and gas media freefrom impurities and particles,where fast and tight shut-offas well as rapid venting are required.
