Chlor-alkali fluorine plastic all the diaphragm Industrial Valves is a kind of special form, which has the function of truncation valve, the opening and closing by steel disc with soft material ( FEP + EPDM compound) Made of diaphragm and the valve body cavity with the Industrial Valves cover inner chamber is separated, in order to achieve the purpose of the cut section of the tube medium.

applicable medium: chlorine, chlorine, hydrogen chloride, refined brine water, high purity hydrochloric acid, sulfuric acid, phosphoric acid, hydrofluoric acid, aqua regia, strong corrosive such as alkali, strong oxidizing medium temperature:

apply - 40 ~ 150 ℃

nominal pressure: PN 1. 0 to 1. 6 mpa ANSI 150 lb JIS 10 k

nominal size: 15-250 NPS DN 1/2 '~ 10'

chlor-alkali fluorine plastic all diaphragm Industrial Valves structure

basic series for the diaphragm valve lining G41F46 weir and G45F46 once-through, its characteristic is as follows: 1.

Composite diaphragm in the lower part of the body cavity with the valve cover inner chamber is separated, and the formation of dc channel, make the diaphragm of the upper stem and disc parts completely isolated with the media, such as save packing seal structure, at the same time to avoid leakage and the leakage of the medium.

2。 body cavity machining special process groove, the enhancement, fluorine plastic and metal substrate, reliable guarantee for lining fluoride performance.

3。 As diaphragm actuators, due to the frequent opening and closing, easy to produce fatigue fracture, should inspect working condition, the characteristics of medium, for regular replacement.
