ZSQN Pneumatic Piston Three-way Shutoff Valve product details

ZMAP-D Pneumatic Film Low Temperature Regulating Valve produced and sold by Baigang Valve Group is composed of ZS type spring piston actuator and cut-off valve. It is light in volume and weight, fast and reliable in cut-off and large allowable pressure difference.It is the executive component of automatic control system, it accepts the two-position regulation instrument, PC program computer and electronic control "on-off" switch signal, cut OFF, open or change the flow direction of medium, realize the two-position control of process parameters, suitable for process pipeline emergency cut OFF and automatic protection interlock system for venting.This series of products have film type, piston type two kinds.The valve body structure has single seat, sleeve, double seat (two three-way) three kinds, the sealing form has packing seal and bellows seal two kinds.It has the advantages of simple structure, large operation force, small size, light weight, small flow resistance, large valve capacity, good sealing performance, convenient maintenance and so on.It is suitable for the automatic control system of gas and liquid medium without granule and impurity, which requires fast and tight closing and fast venting.Widely used in petroleum, chemical, metallurgy, electric power, textile and other production process of automation control system.

ZMAP-D Pneumatic Film Low Temperature Regulating Valve main performance parameters
Type: Pneumatic Piston Actuator
Supply pressure: 0.4-0.7MPa
ZMAP-D Pneumatic Film Low Temperature Regulating Valve Type of action: gas or gas off (the role of three-way shut-off valve The way is on the valve seat, the air is the side of the open at the end of the valve, the valve is the role of the implementing agencies. On the other hand, the gas off the side of the closed at the end.)
Sealing material: PTFE, stainless steel, etc.
Flow characteristics:
Leakage: Metal seat: less than 0.01% of the valve rated capacity, in line with GB / T4213IV-class
soft seat: less than the rated capacity of the valve 10-7, in line with GB / T4213V level
cut off time: 0.5-4 seconds
