G641F46 Pneumatic actuator PTFE-lined fluorine diaphragm valve

https://owlice.en.made-in-china.comI. Product Overview:The internal cavity surface of the G641F46 pneumatic lining fluorine diaphragm valve has a variety of rubber options. Therefore, it has superior corrosion resistance. Because the runner of the diaphragm valve is smooth and the flow resistance is small, a large flow rate can be obtained. It is used to change the direction of path sections and media flow, with functions such as diversion, cut-off, adjustment, throttling, checkback, shunt or overflow. Valves can be used to control the flow of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids.II. Working principle:Separate the lower inner cavity of the valve body from the inner cavity of the valve cover, and form a DC channel with it, so that the stem, disc and other inner parts in the upper part of the diaphragm are completely isolated from the medium, eliminating the packing seal structure, and the leakage and leakage of the media can be avoided at the same time. The surface is evenly coated with a layer of FEP. The inner surface of the valve body channel is smooth, the fluid resistance is small, the CV value is high, the circulation capacity is strong, and the torque is moderate. It adopts a four-stage sealing structure and is equipped with a temperature-resistant and aging SI rubber elastic cushion seat outside the sealing surface, which fully achieves zero leakage of the medium.III. Product features:1. The diaphragm made of soft seals such as rubber or plastic has good sealing. Because the diaphragm is a fragile part, it should be replaced regularly according to the characteristics of the media.2. Due to the limitation of diaphragm materials, the diaphragm valve is suitable for situations with low pressure and relatively low temperature.3. According to the structural form, the diaphragm valve can be divided into six types: roof type, DC type, cut-off type, straight-through type, gate type and right angle type; the connection form of connection is usually flange connection; according to the driving mode, it can be divided into manual, electric and pneumatic, of which the pneumatic drive is divided into normally open type, normally closed type and reciprocating type.4. Generally, it should not be used in pipelines with temperatures above 60 degrees and transporting organic solvents and strong oxidation media, nor should it be used at higher pressure.Technical specification for lining fluorine diaphragm valves:design criteriaGB12239structure lengthJB1688/GB12221Flange standardJB/T79-94GB9113.1-26check testGB/T13927Drive wayManual, electric, pneumatic, andNormally closed type, normally open typeList of main components:order numberpart namegray pig ironcast steelstainless steel*** carbon steelZCPRPLRL1Body, cap, discHT250WCBCF8CF8MCF3CF3M2valve stem351Cr131Cr18Ni19Ti1Cr18Ni12Mo2Ti00Cr18Ni1000Cr17Ni14Mo23The lining layerFEP(F46) PFA PCTFE(F3)4lack of mutual understandingFEP (F46) / CR (fluoroprene) PFA (soluble polytetrafluoroethylene) / FPDM (ethylene propylene rubber) PO5valve-stem nutZCuAL10Fe3 ZCuAL10Fe36bolt35351Cr17Ni21Cr17Ni21Cr17Ni9Ti1Cr17Ni9Ti7nut45450Cr18Ni90Cr18Ni90Cr18Ni90Cr18Ni98hand wheelHT200HT200WCCWCCWCCWCC Frequently asked questions:1.
