Stainless steel soft seal gate valve

Product Features

The concealed soft seal gate valve utilizes the deformation compensation effect generated by the overall sealing of the gate plate to achieve good sealing effect, overcoming the problems of poor sealing, water leakage and rust of general gate valves, and more effectively saving installation space. Used as a regulating and intercepting device on fluid pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textiles, electricity, ships, metallurgy, energy systems, etc.

Stainless steel soft seal gate valveZ45XStainless steel elastic seat sealed gate valveRVHXHidden stem stainless steel elastic seat sealing gate valve/Stainless steel soft seal flange gate valve/304Concealed rod elastic seat sealing gate valve/Stainless steel soft brake/Stainless steel concealed soft seal gate valveThe opening and closing component of the gate valve is the gate valve, and the direction of movement of the gate valve is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or intercepted. The concealed rod elastic seat sealing gate valve utilizes the deformation compensation effect generated by the overall sealing of the valve to achieve a good sealing effect, overcoming the problems of poor sealing, water leakage, and rust in general gate valves, and more effectively saving installation space. Elastic seat sealed soft seal gate valves can be used as regulating and shut-off devices on fluid pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, power, ships, metallurgy, energy systems, etc.

Application scope:

Stainless steel elastic seat sealed soft seal gate valves are particularly suitable for domestic drinking water systems, food and pharmaceutical industries, industrial water supply and drainage and sewage treatment, natural gas and coal gas, etc. Soft seal gate valves can also be widely used in fluid pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, light textile, power, shipbuilding, metallurgy, energy systems, etc.

Structural features:

Flat bottomed valve seat

The bottom of the soft sealed gate valve adopts a full basin straight through flow channel design, which is equivalent to a straight pipeline. It has no stagnant cavity structure, low flow resistance, ensures smooth fluid flow, is not easy to deposit debris, and will not cause secondary pollution to the medium.

Fully covered gate

The gate adopts a stainless steel 304CF8 skeleton wrapped with high-performance rubber, and mature vulcanization technology and advanced vulcanization process completely isolate the gate core from the fluid. The encapsulation is tight and reliable, and its bonding strength meets the requirements of DVGW. Even under frequent compressive stress, the rubber will not fall off. The dual structure of valve stem nut and gate ensures sufficient freedom and flexible opening and closing without any jamming phenomenon.

Replace the sealing ring online

Special shaft seal structure, can replace the sealing ring online without stopping water when fully opened;

Reliable upper seal

The upper seal between the valve stem and the top cover adopts a five channel "O" - shaped sealing ring structure of "inner 3, outer 2". Compared with the packing sealing structure of traditional gate valves, the seal is tight and reliable, and the friction resistance is greatly reduced.

Corrosion Resistance

The inner and outer surfaces of the shell (stainless steel CF8) are electrostatically sprayed with epoxy resin powder, with a uniform and firm coating that never exposes iron; The top of the connecting bolt in the middle chamber is sealed with glue to isolate the bolt from contact with the environment and prevent corrosion.

Food grade hygiene requirements

The inner cavity of the gate valve is sprayed with non-toxic epoxy resin powder, which meets the DVGW standard (Germany) and far exceeds the requirements of GB/T17219; The valve stem, valve stem nut and other internal components are made of stainless steel or bronze, which are not corroded by water; The rubber coating meets the hygiene standards for drinking water.

additional function

It can provide additional functions such as valve opening indication, underground direct burial, anti-theft lock control, etc.
