The valve door frame of the stainless steel slab gate valve is made by welding high-quality stainless steel strips after edge folding. It has good anti-torsion performance, light weight, and is easy to install.

The slab is also made of high-quality stainless steel plates. After edge folding, it is flattened through a special process. The flatness processing is reliable and the sealing performance is good.

The sealing strip is composed of two rubber sealing strips with different cross-sectional shapes. The rubber is made of imported rubber compound formula and injected through a special process. It has good wear resistance and long service life. The sealing surface has four sides: left and right sides and upper and lower sides. The sealing strips on the left and right sides and the upper side have a butterfly-shaped cross-section, which has a double-sealing effect and a self-tightening sealing effect. The lower sealing is a strip-shaped sealing strip. After installation, the bottom is flush with the bottom of the channel. When the medium flows through, it is not easy to deposit sediment at the sealing surface and damage the sealing surface. The slab gate valve can withstand pressure in both positive and reverse directions and can ensure zero leakage. The sealing strip is embedded in the door frame and does not need to be fixed with bolts, making it easy to replace.

The guide rail material adopts lightweight and high-performance nylon alloy. The guide rail is formed in one piece and directly embedded in the door frame without the need for bolt fixation, making it easy to install and disassemble. The slab always moves up and down within the guide rail, with a small friction coefficient, low noise, good wear resistance, and long service life.

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

The slab gate valve can be installed in the form of direct grouting, or the door frame of the slab gate valve can be held by an active installation block, and the slab gate valve is fixed to the wall by fixing an active installation block with a stainless steel expansion bolt. When the stainless steel expansion bolt is about to touch the reinforcing bars of the wall during the fixation of the active installation, it can be moved up and down along the left and right door frames to avoid the reinforcing bars, or it can be avoided through another through hole of the active installation block. The lower door frame can also avoid the reinforcing bars in the above manner. The above characteristics of the slab gate valve make the valve light in weight, easy to install, with good sealing effect, good anti-corrosion performance, and long service life.

Technical Specifications

The manufacturing of the stainless steel slab gate valve meets the technical requirements of GB/T 14173 "Technical Conditions for Plane Steel Gates". This product is a new type of product developed and designed by our company's technicians with reference to foreign technical standards and extensive absorption of advanced domestic and foreign experiences. It is designed with computer modularization, with reasonable and novel design, thorough drainage, and four-sided sealing in both directions. The overall slab gate valve has ultra-high corrosion resistance, which can ensure the long-term use of the valve without maintenance. This slab gate valve mainly consists of a door frame, slab, sealing strip, valve stem, guide rail, active installation block, etc.
