Integrated package glue valve core

Nodular graphite cast iron frame with high performance rubber and the latest vulcanization technology for the overall coating, fit tight solid, precise geometric size, sealing flexibility, and completely remove the metal and fluid core, corrosion resistance.

Integrated copper nut

The valve core of the copper nut and ductile iron skeleton, using special technology closely connected as a whole, to ensure the long-term operation and the impact of the flow will not loose, to avoid causing the valve control failure.

Flat bottom valve seat

The elastic valve seat seal at the bottom of the whole basin through type design, equivalent to all pipelines, easy accumulation of debris, to ensure reliable sealing, the fluid smoothly.

Self sealing valve cover

Between the valve cover and the valve body using self sealing structure design, in the allowable pressure range, the higher the fluid pressure, the closer the seal.

Special seal

Between the stem and the valve cover on the upper seal structure, the use of three o - shaped sealing ring design, compared with the traditional gate valve packing seal structure, the road is tight, a substantial reduction in friction resistance. In the valve is in any open, there is pressure and with the valve stem safety lock function, to ensure that the operation and maintenance of the valve stem will not be pressure out, to avoid causing damage to personnel

Lightweight structure

Compact structure, so that the maximum working height than the traditional gate valve to reduce more than 60mm-300mm, saving the project space; the main body using ductile iron material, the weight is less than the traditional gate valve to reduce about 20%-30%, installation and maintenance convenience.

Food grade hygiene requirements

In the valve body, the inner and outer surface of the valve core is coated with rubber, and the inner and outer surface of the valve core can not be corroded by water or corrosion, and can be directly used for the drinking water system and the food and medicine industry.
