FIBV seramika shishiriladigan kapalak klapani
Strukturaviy xususiyatlar
- ● Keramik disk va rezina klapan o'rindig'i o'rtasida aylanish aşınması yo'q.● Pnevmatik boshqariladigan, past moment talablari va oson parvarishlash uchun yengil aksessuarlarga ega.● Keramik disk yuqori darajada aşınmaya, korroziyaga chidamli va ifloslantirmaydi.
Foydalanish shartlari
- ● Yuqori sızdırmazlık ishlashi va tozaligi juda muhim bo'lgan gaz-qattiq zarrachalar muhitlari uchun mos keladi.● Maksimal harorat: 180 °C● Maksimal bosim: 1.6 MPa● Hajm oralig'i: DN25–250 (1"–12")● Muhrlash klassi: ≥ IV
Ishlashning afzalliklari
- ● Xizmat muddati uzaytirilgan (an'anaviy kapalak klapanlariga qaraganda 2 baravar ko'proq).● Zarrachalarga boy va toza ishlash talablari ostida ishonchli muhrlash.● O'rindiqni tezda almashtirish va past ishga tushirish momenti bilan oson parvarishlash.
