The pneumatic diaphragm cut-off valve is subject to a top guide structure with multi spring diaphragm actuator.There are three types of valve body structure：single seat， sleeve and three-way.It has the advantages of compact structure， lightweight， sensi tv e action， S streamlined fluid passage， small pressure drop loss， large valve capacity， convenient disassembly and assembly， etc.The valve receives the signal from the regulating instrument， cuts off， opens or changes the flow direction of the fluid to achieve the automatic control of the process parameters such as pressure， flow， temperature or liquid level.It is widely used in the automatic control and remotecontrol system of production process of environmental protection water treatment， petroleum， chemical industry， metallurgy， electric power， light industry， textile and other industrial sectors.
