Description
Gate valve
is designed and manufactured according to American Petroleum Institute 6A, 6D
and NACE MRO175 Standards.
The sealing surface of valve seat and gate is overlaid
(surfaced) with hard alloy, resistant to corrosion and abrasion.
Valve seat, gate and stem are sealed with imported lip-shaped
combined seal structure, so they are safe and reliable, and the switching torque
of valves is low. Simple and safe design of valve gate and seat, makes it easy
to change without special tools. Non-rubber seal effectively protects valve
chamber from mud, sand and rock, etc. Stem sealing can be changed under
pressure. Stem is designed to be rising stem and non-rising stem, with a clear
sign for valve opening.
Drive mode falls into manual, hydraulic and gear. Combining
type falls into flange, thread and card box.
