Brief introduction:
The series of gate valves include cast steel gate valve and forged
steel gate valve. They are
designed and manufactured according to ANSI B16.34. With solid
wedge and flexible wedge,
so it can be used for different pressures. Gate valves have back
seal. Back seal of forged-steel gate valve
is weld with stainless steel. So it has perfect sealing. Its
maintenance is
convenient. Widely used in petroleum,chemistry,water treatment
industries.
