Products Name:Soft Seal Gate Valve

Gate valve is one of the most widely used valves in a variety of fluid delivery projects. Traditional gate valve, the prevalence of fluid leakage, serious rust and other internal parts and so on. Currently on the market of ordinary soft-sealed gate valve stem seal easy to leak, can not continue to water and at any opening of the case to replace the seal.

Product Description Of Soft Seal Gate Valve

Gate valve is one of the most widely used valves in a variety of fluid delivery projects. Traditional gate valve, the prevalence of fluid leakage, serious rust and other internal parts and so on. Currently on the market of ordinary soft-sealed gate valve stem seal easy to leak, can not continue to water and at any opening of the case to replace the seal.

Elastic seat sealing gate valve adopts novel structural design, strict manufacturing technology and new material with high performance, overcoming the defects of traditional gate valve sealing, the internal parts are especially prone to rust on the gate, fatigue and aging of rubber elasticity, reliable sealing performance, Operate lightly, maintain simple and convenient, long service life. It is suitable for domestic water system, water supply and drainage system, sewage treatment system, chemical fluid delivery system and so on. It is used as a truncation device in construction, city environmental protection, petrochemical, pharmaceutical, food, metallurgy, textile, electric power and other industries Suitable for throttling).

Features Of Soft Seal Gate Valve

Elastic seat gate valve, the main seal is a rubber-covered monolithic gate, in the operation of force and pressure generated by a small amount of adaptive elastic deformation, and precision casting valve seat to form an excellent seal.

◆ Nodular cast iron shell

Body and bonnet material is ductile iron, high strength and corrosion resistance. Seat and valve body as a whole casting precision casting, without any processing.

◆ full-diameter flat runner

When the valve is fully open, the gate is completely free from the runner, and the groove at the bottom of the valve seat is not easy to accumulate debris, which is the same as that of the straight pipe, and the flow resistance is the lowest.

◆ All bags plastic gate

High-performance rubber will be all wrapped skeleton, cast iron thoroughly with the media isolation, non-corrosive. Rubber soft seal, and the skeleton of the firm knot, the overall heat-vulcanized shape.

◆ Monolithic copper nut

Gate nut and skeleton as a whole connected, no movement of empty trip and loose phenomenon. Bronze material, self-lubricating with the stem, reducing operating torque.

◆ gate rail system

Valve body and gate with rail system. When the gate seal water pressure does not drift, lifting rubber contactless wear, to prevent stem bending.

◆ stainless steel stem

Stainless steel corrosion-resistant stem, trapezoidal thread rolling, thread wear-resistant smooth, effectively reduce the operating torque, improve service life.

◆ Double thrust bearings (dark rod type DN ≤ 300)

Stem neck with double thrust bearings, flip-type stem to avoid being washed out by water pressure. Bronze material, self-lubricating with the stem, reducing operating torque.

◆ Stem axial seal (dark rod type)

Three O-rings, axial self-sealing under water pressure, no packing seal adjustment trouble. Top dust ring to prevent external impurities into the shaft seal inside.

◆ inverted seal structure (dark rod DN ≤ 300)

Patented inverted seal structure, allowing the valve in the water and at any angle in the emergency opening, replace the gland at the O-ring.

◆ flange connection

High-intensity point hole screws, hot-melt adhesives and bonnet rubber ring closed, the screw and the working medium and the external environment completely isolated.

◆ double feet double rings

All specifications of the gate valve, the valve body cast as a whole with two legs, the valve cover cast a total of two rings, easy handling and storage.

◆ non-toxic anti-corrosion coating

The inner and outer surfaces of the valve are made of non-toxic epoxy powder electrostatic coating, anti-corrosion long life, can be used directly for drinking water, food and medicine industries.

◆ various types of operation

Dark rod structure, the rod type. Available handwheel, T-handle, electric, pneumatic and other device operation, the valve position instructions, valve position signal output, password lock control, extend the operating rod, Buried devices to choose from.

◆ installation and construction convenience

With flange, clamp groove, socket, socket, mechanical connectors, PE connectors and other connections, optional telescopic function, and cast iron, steel, plastic and other pipe connections.
