Aplikasi & Fungsi

GW Cast steel Gate valves utamané digunakake kanggo stop valves kanthi kabuka utawa ditutup kanthi lengkap.Padha ora biasane dianggep kanggo tujuan throttling, nanging luwih kanggo slurries, cairan kenthel, etc. Gate klep ditondoi dening wedge lelungan, kang dipindhah karo operasi saka nut stem.Wedge kasebut tegak lurus karo arah aliran.Katup gerbang biasane duwe penurunan tekanan minimal nalika mbukak kanthi lengkap, nyedhiyakake tutup sing ketat nalika ditutup kanthi lengkap, lan tetep bebas saka penumpukan kontaminasi.

Aksesoris

Aksesoris kayata operator gear, aktuator, bypass, piranti ngunci, roda rantai, batang lan bonnet lengkap kanggo layanan cryogenic lan liya-liyane kasedhiya kanggo nyukupi kabutuhan pelanggan.
