Dhinaca maareynta dareeraha warshadaha, daacadnimada xiritaanka valve waa muhiim. Sansheng Fluorine Plastics waxay soo bandhigaysaa alaabteeda calanka ah, Fayodhowrka Compound Butterfly Valve Seling Ring, oo loo farsameeyay heer sare. Xalkan cusub ee xiritaanka ayaa si taxadar leh loo sameeyay iyadoo la isku darayo adkeysiga EPDM iyo iska caabbinta kiimikaad ee PTFE, taasoo keentay giraan xirmo cad iyo madow ah oo aan muuqaal ahaan kala duwanayn laakiin sidoo kale aad u shaqeynaya.



Fayodhowrka Compound Balanbaalista Valve Seling Ring waxay u taagan tahay isku dhafka tayada iyo wax-soo-saarka. Naqshadeynta si ay u adkeyso cadaadiska u dhaxeeya PN6 ilaa PN16 iyo Class 150, waxay marag u tahay sida ay nooga go'an tahay gaarsiinta alaabada buuxisa shuruudaha warshadaha kala duwan. Haddi nidaamkaagu gudbiyo biyaha, saliida, gaaska, ama kiimikooyinka gardarrada ah, giraantan xidhidhisku waxa ay hubisaa in ay daadsan yihiin- hawlgal caddayn ah, si kor loogu qaado waxqabadka iyo yaraynta khataraha la xidhiidha dareeraha dareeraha ah noocyada iyo cabbirrada, laga bilaabo DN50 ilaa DN600. Haddii aad ku dhex darayso nooca wafer-ka khadka dhexe ee jilicsan ee xidhidhiyaha balanbaalista ama wafer balabaalista oofwareen, rakibiddu waa bilaa tol. Iyada oo la kala dooranayo isku xirka wafer ama flange iyo u hoggaansanaanta heerarka caalamiga ah oo ay ku jiraan ANSI, BS, DIN, iyo JIS, giraantan xirida runtii waa mid caalami ah. Ma aha oo kaliya qayb laakiin waa rukunka maaraynta dareeraha hufan, waxaa loogu talagalay in lagu daboolo baahiyaha warshadaha halka nadaafadda, adkeysiga, iyo caabbinta kiimikadu aysan ahayn - gorgortanka.
