The gate valve frame is welded by high-quality stainless steel plate after being folded, with good torsion resistance, light weight and convenient installation;

The ram is also made of high-quality stainless steel plate, after being folded, it is leveled by special process, with reliable flatness processing and good sealing performance;

The sealing belt is composed of two rubber sealing belts with different cross section shapes. The rubber is made of imported rubber formula and injected with special process, which has good wear resistance and long service life. The sealing surface is divided into left and right sides and upper and lower sides. The cross section of the sealing belt on the left and right sides and upper sides is butterfly shaped, which has dual sealing effect and self tightening force sealing effect. The lower side seal is a ribbon sealing belt. After installation, the bottom is flush with the bottom of the channel, When the medium flows, it is not allowed to deposit sediment on the sealing surface to damage the sealing surface. The gate valve can achieve positive and negative pressure, and can ensure zero leakage. The sealing belt is embedded in the door frame, which is not fixed with bolts and is easy to replace.

The guide rail is made of nylon alloy with light weight and excellent performance. The guide rail is formed at one time and directly embedded in the door frame. It does not need to be fixed with bolts and is easy to install and remove. The ram always moves up and down in the guide rail, with low friction coefficient, low noise, good wear resistance and long service life.

The opening and closing mechanism can adopt manual, electric, pneumatic and other devices. The connection between the valve plate and the valve stem adopts a movable cylindrical pin, which can quickly and conveniently remove the valve stem that does not pass through the opening and closing mechanism.

The gate valve can be installed in the form of direct grouting, or the gate frame of the gate valve can be fastened with a movable mounting block, and a movable mounting block can be fixed on the wall by a stainless steel expansion bolt. When the stainless steel expansion bolt is fixed to the wall reinforcement during the movable installation, it can move up and down along the left and right door frames to avoid the reinforcement, or avoid the left and right reinforcement through another through hole of the movable installation block. The lower door frame can also avoid the reinforcement according to the above method. The above characteristics of gate valve make the valve light, easy to install, good sealing effect, good anti-corrosion performance and long service life.

Technical specifications

The manufacture of stainless steel gate valve shall meet the technical requirements of GB/T14173 Technical Conditions for Plane Steel Gate. This product is a new type of product developed by our technicians with reference to foreign technical standards and extensive absorption of advanced experience at home and abroad. It is designed by computer modularization. It is reasonable, novel, completely drained, and has two-way four side sealing. The overall gate valve has ultra-high corrosion resistance characteristics, which can ensure the long-term use and maintenance free of this valve. The gate valve is mainly composed of door frame, gate, sealing belt, valve stem, guide rail, movable mounting block, opening and closing mechanism, etc. The gate valve is mainly used for municipal water supply and drainage, and the sewage treatment plant can cut off and regulate the flow.
