In addition to the advantages of elastic seat sealed gate valves, groove copper core gate valves can also display the degree of valve opening more intuitively, so as to distinguish the degree of valve opening from a distance and take corresponding measures in a timely manner. Opening and closing are commonly used in fire protection systems.

The upper sealing structure between the valve stem and the valve cover adopts a design of three O-ring seals. Compared with the packing sealing structure of traditional gate valves, the channel seal is tight and the friction resistance is greatly reduced. When the valve is at any opening, under pressure, and has a valve stem locking function, the valve stem will not be pushed out by pressure during operation and maintenance, avoiding personal injury

Lightweight structure

The compact structure reduces the working height by over 60mm to 300mm compared to traditional gate valves, saving construction space; The body is made of ductile iron material, which reduces the weight by about 20% -30% compared to traditional gate valves, and is easy to install and maintain.

Hygiene requirements

The interior of the valve body is coated with epoxy resin, and the inner and outer surfaces of the valve core are covered with rubber, which will not cause rust or corrosion. It can be directly used in drinking water systems and the food and pharmaceutical industry.
