BS1868 aylanma nazorat valfi
GW BS1868Swing nazorat valfi
BS1868 tebranish nazorat valfi nasoslar va kompressorlar kabi jihozlarni himoya qilish uchun potentsial zarar etkazuvchi teskari oqimlarni oldini oladi.Qaytarilmaydigan valflar suyuqlikning faqat bir yo'nalishda oqishiga imkon beradi va teskari oqimlarni bloklaydi.U eng sodda dizaynga ega va yuqoridagi ilgakka biriktirilgan metall disk orqali ishlaydi.suyuqlik aylanma nazorat valfi orqali o'tganda, vana ochiq bo'ladi.Teskari oqim sodir bo'lganda, harakatdagi o'zgarishlar, shuningdek, tortishish diskni yopishga, valfni yopishga va teskari oqimlarning oldini olishga yordam beradi.
