Elastic seat seal gate valve, the main seal is the rubber covered integral gate plate, under the action of operation force and water pressure to produce a trace of adaptive elastic deformation, and precision cast seat to form an excellent sealing effect.
Ductile iron investment cast shell
Body and cover made of ductile iron, high strength and corrosion resistance. The valve seat and body are precision cast without any machining.
full-diameter flat bottom runner
When THE VALVE IS FULLY OPENED, THE GATE is completely generated from the flow channel, the bottom of the seat has no groove, not easy to accumulate debris, the same as the straight pipe, the lowest flow resistance.
All rubber coated RAMS
High-performance rubber will be wrapped all the skeleton, cast iron completely isolated from the medium, no corrosion. Rubber soft seal, and the skeleton firm fine knot, the whole hot vulcanization forming.
Integral copper nut
The gate nut is completely connected with the skeleton, without empty stroke and loose phenomenon. Bronze material, self - lubricating with valve stem, effectively reduce operating torque.
Gate guide rail system
Guide rail system between valve body and gate. The bearing water pressure is not offset when the gate is sealed, and the rubber does not contact and wear when it is lifted or lifted to prevent the stem from bending.
Stainless steel valve stem
Stainless steel corrosion-resistant stem, trapezoidal thread rolling processing, smooth and wear-resistant screw teeth, effectively reduce operating torque, improve service life.
Double thrust bearing (dark rod type DN≤300)
Stem neck with double thrust bearings, inverted stem to avoid water flush. Bronze material, self - lubricating with valve stem, effectively reduce operating torque.
Axial seal of valve stem (dark rod type)
Three O ring, under the action of water pressure axial self-sealing, no packing seal adjustment trouble. Top dust retaining ring to prevent external impurities from entering the shaft seal.
Reverse sealing structure (dark rod type DN≤300)
Patented INVERTED SEAL CONSTRUCTION ALLOWS THE VALVE TO REPLACE THE O-RING at the gland in the event of constant water and emergency at any Angle opening.
Middle flange connection
High strength inner hole Angle screw, hot melt adhesive and valve cover rubber ring seal, completely isolate the screw from the working medium and external environment.
Double legs and double rings
For all specifications of GATE valves, the valve body is cast with two legs and the valve cover is cast with two rings for easy handling and storage.
Non-toxic anti-corrosion coating
The internal and external surfaces of the valve are coated with non-toxic epoxy powder electrostatic coating, corrosion resistance and long life, which can be directly used in drinking water, food and medicine industries.
Various types of operation
Structure has dark bar type, clear bar type. It can be operated by HANDwheel, T-shaped handle, electric and pneumatic devices, valve position field indication, valve position signal output, password lock control, extended lever, direct embedding device and so on.
Easy installation and construction
With flange, clamp groove, socket, socket, mechanical joint, PE joint and other connection modes, optional expansion function, convenient connection with cast iron, steel, plastic and other pipes.
