Product overview
On the market for a long time
to use a common general valve leakage or rusty phenomenon, the company
introduced the European high-tech rubber seal of the elastic base seat
and valve manufacturing technology of gate valve, overcomes the general
bad, elastic fatigue, aging of rubber gate valve seal and defects such
as rust, seal gate valves using the elastic of the elastic base seat
valve production trace elastic deformation compensation function to
achieve good sealing effect, The valve has the obvious advantages of
light switch, reliable sealing, good elastic memory and long service
life. Can be widely used in water, sewage, construction, petroleum,
chemical, food, medicine, textile, electric power, shipbuilding,
metallurgy, energy systems and other fluid pipeline as a regulation and
closure device.
Features:
Light WEIGHT: THE body
material IS MADE OF advanced ductile iron, THE weight is about 20%~30%
less than the traditional gate valve, easy to install and maintain.
Flat
type seat: traditional gate valves are often in the water after washing
pipe for objects such as stone, wood blocks, cement, iron filings,
impurities, such as silt on the bottom of the valve inside the groove,
easy to cause cannot close tightly and form slack phenomenon, at the
bottom of the seal of the elastic base seat gate valves used in the pipe
of the same flat design, not easy to cause debris deposition, make the
flow unimpeded.
Overall coating: The valve is made of high quality
rubber for the whole inside and outside the rubber, Europe's first-class
rubber vulcanization technology using vulcanized valve can ensure
accurate geometric size, and rubber and ductile iron valve is then
reliable, not easy to fall off and elastic memory is good.
Precision
CAST VALVE BODY: THE VALVE body IS PRECISION cast, the precise geometry
of the valve body without any finishing can ensure the sealing of the
valve.
Embedded nut: Threaded and elastic valve using embedded joint,
so that the two closely combined into one, not due to water flow caused
by vibration and loose or damage phenomenon.
Corrosion resistance:
The body is coated with epoxy resin powder, which can prevent the
corrosion and rust of the body, and can be used in sewage system.
Not
easy to break: traditional cast iron gate valves are often broken due
to external impact, collision or weight. This situation can be greatly
reduced by using nodular cast iron.
Three "O" ring seal: Because the
valve stem adopts three "O" ring seal design, it can reduce the friction
resistance when closed and reduce the water leakage phenomenon and can
replace the seal ring without stopping.
For RAW DRINK: AS THE INSIDE
OF THE VALVE BODY IS COATED WITH NON-TOXIC EPOXY RESIN, THE INNER AND
OUTER SURFACES OF THE VALVE ARE COMPLETELY COVERED WITH RUBBER TO
PREVENT RUST OR CORROSION, AVAILABLE FOR RAW DRINK.
