ZSPC Pneumatic Piston Shutoff Valve product details

ZSPC Pneumatic Piston Shutoff Valve Overview:

ZSPC Pneumatic Piston Shutoff Valve produced and sold by Baigang Valve Group is composed of pneumatic piston actuator and cutting off machinery.According to the sealing surface material of the valve core can be divided into hard seal and soft seal: according to the structure of the valve core can be divided into single-guide plate type and single-guide balance type.It has the characteristics of simple structure, reliable action, tight cutting, fast closing and so on.It is suitable for the automatic control system in which the gas and liquid media without granule and impurity are required to be closed and emptied quickly.
