Product Features

Core Structural Advantages

1. Overall Rubber Coating

The valve core of the Rising Stem Soft Sealing Gate Valve adopts the latest vulcanization technology and high-performance rubber overall rubber coating, which is tightly coated, accurate in geometric dimensions, reliable in sealing and has a long service life. The overall rubber coating can completely isolate the valve core from the medium, avoid corrosion and wear, and ensure the stable operation of the product for a long time. At the same time, the rubber material has good elasticity, which can automatically compensate for the slight deformation of the valve core, further improving the sealing performance.

2. Light Weight & Space-Saving Design

The valve body is made of ductile iron, which can reduce the weight by about 25% compared with ordinary gate valves, and is very convenient for installation and maintenance; the maximum opening height of the gate valve is generally 60mm~280mm, and it can also be installed on demand in places with small spaces. The lightweight design not only reduces the transportation cost, but also reduces the load of the pipeline, avoiding the damage to the pipeline caused by the excessive weight of the valve. In addition, the compact structure of the product makes it suitable for installation in narrow spaces such as underground pipelines and equipment cabins.

3. Three "O" Seals for Leakage Prevention

The valve stem seal uses an O-ring seal, which has low friction, light weight and no water leakage. The three "O" seals are arranged in the upper part of the valve stem, forming a multi-layer sealing protection system, which can effectively prevent the medium from leaking along the valve stem, ensuring the safety and environmental protection of the operation process. The O-ring is made of high-temperature and corrosion-resistant material, which can adapt to different working temperature ranges and medium types, and has a long service life without frequent replacement.

4. Clear Opening & Closing Indication

As a rising stem valve, the Rising Stem Soft Sealing Gate Valve can clearly show the opening and closing state through the lifting height of the valve stem during the operation process. The upper part of the valve stem is marked with a scale, which can accurately judge the opening degree of the valve, avoiding misoperation caused by unclear state. This design is especially suitable for important pipeline systems that require precise control, ensuring the safety and stability of the production process.

5. Smooth Operation & Low Wear

The valve stem and valve core adopt precision machining technology, with high matching accuracy, low friction coefficient during operation, and light and flexible opening and closing. The middle part of the Rising Stem Soft Sealing Gate Valve is equipped with a wear-resistant sleeve, which can reduce the wear between the valve stem and the valve body, prolong the service life of the product. At the same time, the valve stem is treated with anti-corrosion technology, which can effectively resist the corrosion of the medium and the external environment, ensuring long-term stable operation.

Material Advantages

1. High-Quality Valve Body Material

We select high-quality ductile iron, WCB and SS materials for the valve body of the Rising Stem Soft Sealing Gate Valve. These materials have the characteristics of high strength, good toughness, corrosion resistance and wear resistance, which can adapt to various harsh working environments. The ductile iron valve body has good shock absorption performance, which can reduce the impact of fluid on the valve body and extend the service life; the WCB material is suitable for high-temperature and high-pressure working conditions, with strong stability; the SS material has excellent corrosion resistance, which is suitable for pipelines containing corrosive media.

2. High-Performance Sealing Material

The sealing ring of the Rising Stem Soft Sealing Gate Valve is made of high-quality nitrile rubber, EPDM or fluorine rubber, which has good elasticity, wear resistance, high temperature resistance and corrosion resistance. Different sealing materials can be selected according to the type of medium and working temperature, ensuring the sealing performance of the product under different working conditions. The sealing material is non-toxic and harmless, in line with the hygiene standards of food, medical and other industries, and can be safely used in related fields.

At the same time, we have established a strict quality control system, and each product will go through multiple tests before leaving the factory to ensure the quality and performance of the product.

2. Advanced Vulcanization Technology

The overall rubber coating of the valve core adopts the latest vulcanization technology, which makes the rubber and the valve core closely combined, without peeling or falling off. The vulcanization temperature and time are strictly controlled, ensuring that the rubber has good elasticity and wear resistance. This technology can effectively improve the sealing performance and service life of the Rising Stem Soft Sealing Gate Valve, making the product more competitive in the market.

Reliable Performance Advantage

1. High Sealing Performance

The combination of overall rubber coating and three "O" seals makes the Rising Stem Soft Sealing Gate Valve have excellent sealing performance, achieving zero leakage. Even in high-pressure and high-temperature working environments, it can maintain stable sealing, avoiding the waste of medium and environmental pollution caused by leakage. The middle part of the product is the core sealing area, and the reasonable structural design ensures that the sealing performance is not affected by the opening and closing times.

2. Long Service Life

The selection of high-quality materials and advanced production technology ensures that the service life of the Rising Stem Soft Sealing Gate Valve is more than 10 years under normal use conditions. The upper part of the valve stem is treated with anti-corrosion and anti-wear, the middle part of the sealing ring is made of high-performance material, and the lower part of the valve body is strong and durable, which together extend the service life of the product. Compared with ordinary gate valves, our product has a longer service life, which can effectively reduce the replacement cost of customers.

3. Strong Adaptability
