Le valve yokuhlola ejikelezayo ikhiqizwe ngokuvumelana nezindinganiso zezimboni zaseMelika i-API 594 kanye ne-ASME B16.34. Umzimba wevalve uphonswe ngokuphelele ngensimbi ye-WCB carbon steel, isebenzisa isakhiwo se-bolted bonnet swing disc. Iqhutshwa ingcindezi yokugeleza koketshezi namandla adonsela phansi, i-swing disc ivula ngokuzenzakalelayo ukuze uketshezi lugeleze phambili futhi ivale ngokuqinile ukuvimba ukugeleza emuva, okuvikela ngempumelelo amaphampu epayipi, izinsimbi, neminye imishini emonakalweni obangelwa ukugeleza emuva. Indawo yokuvala eqinile yensimbi ifinyelela ukungavuzi okuthembekile ngaphansi kwezimo zomsebenzi ezinengcindezi ephezulu.
