Light Weight
The valve is made up of ductile cast iron similar to resin sand’s
structure and will have high strength and small volume which makes
its weight about 70% ~ 80% of general gate valve’s. It is
easier to install and maintain these valves in the pipe-line.
No - grooved body cavity
There is no groove in resilient seated gate valve’s body, so
the resistance to fluid is little and no sundries piled up in the
body and fluid can flow without block.
Wedged rubber - packed wholly
The outside rubber adheres to the metal wedge tightly and will not
fall off from the metal wedge. The rubber is having good elasticity
and the whole wedge is replaceable.
Close tolerance cast valve body
The body is made up of close tolerance casting and can ensure the
valve’s sealing effect without machining the internals of
the body.
Corrosion resisting
External and internal surfaces of the valve are treated with epoxy
coated of 300 microns and the trims are made up of stainless steel
or copper alloy to prevent the valve body from rusting.
O - ring
There are three pieces of O - ring in the cover for sealing, which
decreases the friction force as well as leakage and the O - rings
can be replaced in line.
Beneficial to drinking
The valve’s external and internal surfaces are treated with
non poisonous epoxy resin and the disc is rubber - packed which avoid
rust and corrosion problem and the fluid is unpolluted for drinking.
