Product Usage

In addition to the advantages of the elastic seat sealing gate valve, the flexible rod sealing gate valve can be opened and closed quickly and reliably, so it is often applied to fire and industrial systems. Generally installed at the ground.

Structural features

Overall rubberized spool

The spheroidal graphite cast iron frame is integrally coated with high-performance rubber and the latest vulcanization technology. The fit is tight and firm, the geometrical dimensions are accurate, the sealing elasticity is good, and the valve core metal is completely isolated from the fluid and corrosion-resistant.

One-piece copper nut

The copper nut of the valve core and the ductile iron skeleton are tightly connected by a special process to ensure that the long-term operation and water flow impact will not be loosened, and the valve control failure will be avoided.

Flat bottom seat

The bottom of the company's elastic seat sealing valve adopts the full-flow straight-through design, which is equivalent to the straight pipe, which is not easy to accumulate debris, ensuring reliable sealing and smooth fluid flow.

Self-sealing bonnet

The self-sealing structure is designed between the bonnet and the valve body. The higher the fluid pressure, the tighter the seal is within the allowable pressure range.

Special upper seal

The upper sealing structure between the valve stem and the valve cover adopts three o-ring seals. Compared with the packing seal structure of the traditional gate valve, the channel seal is tight and the friction resistance is greatly reduced. The valve is at any opening, pressure and has a valve stem safety lock function to ensure that the valve stem will not be rushed out during operation and maintenance, avoiding personal injury.

Lightweight structure

The compact structure makes the maximum working height lower than the traditional gate valve by 60mm-300mm, saving engineering space; the body is made of ductile iron material, the weight is reduced by about 20%-30% compared with the traditional gate valve, and the installation and maintenance are convenient.

Food grade hygiene requirements

The inside of the valve body is coated with non-toxic epoxy resin. The inner and outer surfaces of the valve core are completely covered with rubber, and there is no rust water or corrosion. It can be directly used in the drinking water system and food and medicine industry.
