ZXT type adopts multi-spring actuator, height and weight can be reduced by 30%. The inner surface of the valve body is coated with a variety of materials to avoid direct contact with the medium and withstand the corrosion of the strong valve corrosive medium. When the valve is closed, the amount of internal and external leakage is zero, especially suitable for highly toxic media or not allowed to pollute the medium of the valve joint. The flow path is simple, the resistance is small, and the rated flow coefficient is larger than that of the same caliber single seat and sleeve regulating valve.
Main parts material: valve body: HT200, ZG230~450 or the above material lining diaphragm: butadiene rubber, natural rubber, PTFE corrugated film: nitrile rubber clip reinforced polyester fabric spring: 60S12Mn body lining material and application range Valve body lining temperature (ºC) applicable media
