TEXNIK TALABLAR:
● DIN EN 13709 、 DIN 3356 ga muvofiq dizayn va ishlab chiqarish
● Flanj o'lchamlari EN1092-1 PN16 ga mos keladi
● Yuzma-yuz o'lchamlar EN558-1 ro'yxati 1 ga mos keladi
● Sinov EN12266-1 ga mos keladi
Oqimni tartibga solish yoki bosimni tartibga solish mavjud, ammo tartibga solishning aniqligi yuqori emas va quvur liniyasining diametri nisbatan kichik.Masalan, nominal diametri ≤ 50 mm bo'lgan quvur liniyasida to'xtash valfi yoki gaz kelebeği valfi tanlanishi kerak;
Shahar qurilishida suv ta'minoti va isitish loyihalari uchun, nominal diametri kichik bo'lsa, to'xtash valfi, muvozanat valfi yoki pistonli valfni tanlash mumkin, masalan, nominal diametri 150 mm dan kam bo'lgan quvur liniyasida;
DN200 dan past bo'lgan bug 'va boshqa o'rta quvurlarga qo'llaniladi;
Yuqori viskoziteli muhit uchun mos emas;
Oson cho'ktiriladigan zarrachalarni o'z ichiga olgan muhitga taalluqli emas;
Shamollatish valfi va past vakuum tizimining valfi sifatida ishlatilmasligi kerak.
