Product Description

Product characteristics

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.

Parts Material

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

Valve body lining	Service temperature (C)	Applicable medium
Unlined	-10 ~ +175	Suitable for non-corrosive media
Soft rubber	-10 ~ +85	Has good wear resistance, suitable for cement, clay, coal dust, dry fertilizer and so on
Ebonite	-10 ~ +85	Suitable for non-mechanical, salt, hydrochloric acid, gold-plated solution, soft water, chloride, chlorine, etc
Neoprene adhesive	-10 ~ +105	Animal oil, vegetable oil and lubricant corrosive mud
Butyl gum	-10 ~ +120	Good corrosion resistance and wear resistance, best corrosion resistance to most inorganic acids and acid mortar
Enamel	-10 ~ +175	Suitable for warm inorganic acids, oxidizing acids, halogens, alcohols, esters and other compounds
Fluorine 46	-10 ~ +190	Suitable for strong corrosive media such as sulfuric acid, hydrochloric acid and sodium hydroxide

Precautions

 

Diaphragm material	Temperature to use (C)	Applicable medium
Butyl gum (Grade B)	-40 ~ +100	Inorganic acids such as: sulfuric acid, hydrofluoric - acid, phosphoric acid and other bases and salts
Natural glue (Grade Q)	-50 ~ +100	Mainly used to purify water, inorganic salts and alene mineral acid medium
Polytetrafluoroethylene	-10 ~ +150	Excellent chemical stability, resistance to strong acid, concentrated alkali, strong oxidant corrosion
