Features: The overall package of plastic: gate using high quality rubber within the overall outsourcing glue, Europe's leading rubber vulcanization after curing technology allows the gate to ensure accurate geometry, and rubber and ductile gate Next reliable, high-temperature pressure valves, not falling, and good elastic memory. Water Body Casting: Valve using precision casting, Shandong valve, precise geometry makes finishing without any internal body to ensure that the valve seal. Press the housing / body material classification, valve can be divided into: metal materials Valves: such as carbon steel valves, alloy steel valves, stainless steel valves, cast iron valves, titanium valves, Monel valves, copper alloy valves, lead alloy valves. Metal body lined valves: as rubber lined valves, lined valves, lead-lined valves, lined valves, lined valves enamel. Non-metallic materials Valves: such as ceramic valves, glass valves, plastic valves. Valve closed, sealing surface can only rely on media pressure to seal, that rely only on medium z41h wedge gate valve flange sealing surface pressure to ram pressure to the other side of the seat to ensure the sealing surface of the seal, valve, which is self-sealing. Most of the valve is sealed by force, that the valve is closed to rely on external pressure to force the gate valve to ensure that the sealing of the sealing surface.
