Premium Grooved Non-Rising Stem Gate Valve for Industrial Use

Product Description

Product Description

 

General Description

The Grooved Non - Rising Stem Gate Valve is a high - performance valve designed for a wide range of applications. It features a unique design that combines reliability, durability, and easy operation.

Design Features

• Flat - Bottom Design: Unlike traditional gate valves, the bottom of this valve adopts a flat - bottom design that is the same as the water pipe. This design prevents debris from accumulating, ensuring smooth fluid flow and effectively solving the problem of poor sealing and water leakage caused by the groove at the bottom of the traditional gate valve.
• Integral Rubber Coating: The gate is integrally coated with EPDM rubber or other materials both inside and outside. This rubber coating has excellent anti - aging and anti - radiation properties, and it is durable with good elasticity. It not only ensures a good sealing performance but also extends the service life of the valve.
• Self - Sealing Bonnet: The bonnet and the valve body adopt a self - sealing structure design. Within the allowable pressure range, the higher the fluid pressure, the tighter the seal, which enhances the sealing performance and reliability of the valve.
• Upper Sealing Structure: The upper sealing between the valve stem and the bonnet adopts three O - ring seals. Compared with the packing seal structure of traditional gate valves, the friction resistance is greatly reduced, and each seal is tight. At the same time, when the valve is at any opening and under pressure, it has a valve stem locking function to prevent the valve stem from being ejected by pressure during operation and maintenance, ensuring the safety of personnel.

Material Selection

• Corrosion - Resistant Materials: The valve body is made of cast iron and ductile iron. The appearance is coated with powder epoxy resin to prevent the valve body from corrosion and rust. It is suitable for a variety of media, including cold water, hot water, sewage, oil, gas, etc., which improves the corrosion resistance and adaptability of the valve.
• High - Performance Rubber: The rubber coated on the gate adopts high - performance rubber and new vulcanization technology. It is closely and firmly adhered, with accurate geometric dimensions and good sealing elasticity. It isolates the metal of the valve core from the fluid, not only ensuring the sealing effect but also meeting the hygienic requirements. It can be directly used in the domestic drinking water system, food and pharmaceutical industries.

Manufacturing Process

• Precision Casting Process: The valve body is made by casting process. The precise geometric dimensions ensure that the internal part of the valve body does not need any finishing to ensure the sealing performance of the valve. This improves the production efficiency and product quality and reduces the production cost.

Functional Advantages

• Flexible Operation: It has the characteristics of simple structure and flexible operation. When operating manually, the valve can be easily opened and closed by turning the handwheel, which is labor - saving and convenient. Some valves can also be equipped with electric, pneumatic and other driving devices to achieve automatic control to meet the needs of different working conditions.
• Reliable Sealing: Through the integrally coated gate, special sealing structure and precise manufacturing process, good sealing performance is achieved, which can effectively prevent medium leakage and ensure the normal operation of the system.
• Wide Application Range: It is widely used in pipeline projects such as water supply and drainage, fire protection, air - conditioning, gas, petroleum, chemical industry, water treatment, municipal administration and shipbuilding to control the fluid. It can adapt to different media and working conditions.
