5611BJacketed Insulating Single-Seated Control Valve
Brief Description

Valve disc of Type 5611B Jacketed Insulating Single-Seated Control Valve is top guiding structure, and its composition is compact-type, moreover, its S streamline access can reduce the pressure drop, promote flow rate and have variable range , also enhance its accuracy of flow characteristic to meet IEC534 specifications, which is suitable for thermal insulation service. When the crystallizing point of process medium below environment temperature or flow temperature reduction, which can cause viscosity increasing or flow curing , install steam Jacketed Insulating device on body and bonnet , which can make the processes continue as per requirements. Control valve leakage accord with ANSI B16. 104 standards. Control valve equipped with multi-spring diaphragm actuator, which has the advantages of compact-type structure and large output force.
