First, clear rod soft seal gate valve product overview
Ming rod soft seal gate valve in addition to the advantages of the
elastic seat gate valve, and can be more intuitive display valve
opening, opening and closing quickly and reliably, it is often used in
fire and industrial systems. Generally installed at a higher position
from the ground. I plant the introduction of European high-tech valve
manufacturing technology produced by the seat block valve, the use of
the whole door plastic deformation generated deformation effect to
achieve a good sealing effect, to overcome the poor general valve seal,
leakage and rust phenomenon. It can be widely used as a regulating and
intercepting device in fluid lines such as tap water, sewage,
construction, petroleum, chemical, food, medicine, light injury,
electric power, shipping, metallurgy and energy system.
Second, the characteristics of open-rod soft seal gate valve
1, the overall plastic package: The gate with the overall plastic
package, its good coverage and precise geometric dimensions to ensure
reliable sealing, life expectancy.
2, light weight: made of ductile iron body, light weight, easy to install.
3, flat bottom valve seat: the bottom of the same flat-type valve seat
with water pipe design, does not produce debris siltation, sealing more
reliable.
4, corrosion-resistant: Cavity non-toxic epoxy coating to prevent
corrosion and rust, not only for drinking, but also for the sewage
system.
5, three "0" seal: the stem adopts three 0-ring seal, friction resistance, light switch, watertight.
