Dizayn xususiyatlari
Lugged gofret nazorat valfi o'rnatish va texnik xizmat ko'rsatishda tejamkor, chunki o'rnatish kamroq va engil vazn talab qiladi.
Yuklangan gofretni tekshirish valfi orqaga oqimdan oldin valfdagi kamonni ishlatib, valf diskini yopish tufayli suvning bolg'alanishini oldini olish mumkin.Bundan tashqari, Due-Check valfi katta bo'shliqlar uchun suv sathining katta quvurlarini oldini oladi.
Mavjud nazorat klapaniga qaraganda uzoqroq chidamlilik, oson parvarishlash tufayli texnik xizmat haqini kamaytirish mumkin.
Qopqog'i yo'q bo'lgan lug'atli gofretli nazorat valfi to'rtta asosiy turda mavjud: gofret, tishli, qattiq ushlagich, gardishli uchi.
Tutqichsiz duo nazorat klapanlari tanada oqish muammosiga ega emas.Gofret turi dizayni valfni murvat va gardish bilan mahkamlaydi.
Tutqichsiz duo nazorat klapanlari murvat va gaykalar bilan bog'langan birlashtiruvchi gardishlar orasiga mahkamlangan.
