In modern industrial and municipal pipeline systems, gate valves are among the most common and critical fluid control components, primarily used for opening, closing, isolating, and controlling the entire pipeline flow. With their simple structure, reliable sealing, low flow resistance, and wide applicability, gate valves are widely used in water treatment, oil and gas, chemical, power, fire protection, mining, and municipal construction.
As a professional valve manufacturer, WEIZIDOM offers a diverse range of high-quality gate valve products to meet various operating conditions and supports customization and engineering support services.
1. Soft Seal Gate Valve Series
💡 BS5163 Rising Stem Soft Seal Gate Valve
This is a soft-seal gate valve that uses high-performance elastic sealing materials, effectively overcoming the sealing failure problems of traditional gate valves. It is suitable for media such as water, gas, and oil. Its optimized structure results in low maintenance costs and a long service life.
💡 DIN F5 Resilient Seated Gate Valve
A soft-seal gate valve conforming to German DIN standards. It achieves excellent sealing through a resilient sealing ring, preventing leakage and suitable for applications such as water treatment plants and wastewater systems.
💡 Underground Cap Soft Seal Gate Valve
This soft-seal underground gate valve is suitable for installation in underground piping systems. Its protective cap prevents sediment and impurities from entering the valve body, enhancing durability and reliability.
2. Metal and Steel Gate Valves
💡 Stainless Steel Flange Gate Valve
Made of 304/316 stainless steel, this valve offers excellent corrosion resistance, high-temperature resistance, and low-temperature resistance, making it suitable for harsh environments such as oil, natural gas, chemical, and high-temperature steam.
💡 Stainless Steel Threaded Gate Valve
This stainless steel threaded gate valve features a compact design, easy installation, and is suitable for small-diameter piping systems. It exhibits excellent resistance to corrosive media.
💡 Rising Stem Forged Steel Gate Valve
This forged steel gate valve is suitable for high-pressure, high-temperature applications, such as oil and natural gas transmission systems. The forging process enhances the valve body’s strength and durability, resulting in low flow resistance and excellent sealing performance.
3. Engineering and Firefighting Gate Valves
💡 ANSI Soft Sealing Gate Valve 200PSI
Compliant with AWWA C515 standard and FM/UL certified, this is a commonly used high-quality soft-seal valve in fire-fighting water supply systems.
💡 API Slab Gate Valve (API 6D)
API 6D standard gate valves are suitable for oil and gas pipeline systems, supporting multiple actuation methods (manual, gear, electric, pneumatic), and featuring high reliability, a wide diameter range, and strong pressure resistance.
💡 DN1000 Extension Stem Double Flange Soft Seal Gate Valve
The extended stem double flange design is suitable for deep wells or underground installations with limited space, allowing for remote operation and effectively preventing stem corrosion.
The structural characteristics of gate valves make them excellent in applications requiring full-channel opening and closing, minimal pressure drop, and long-term stable operation:
1. Water Supply and Drainage Systems and Water Treatment Systems: Precise control of large-diameter water flow.
2. Oil and Gas Pipelines: API standard gate valves can withstand high pressure and meet safety requirements.
3. Chemical and Energy Industries: Corrosion-resistant materials are suitable for various chemical media.
4. Municipal Engineering and Fire Protection Systems: Compliant with ASME soft-seal design, suitable for fire water supply.
5. Industrial Manufacturing and Mining: Maintains reliable performance under high temperature and high pressure conditions.
When selecting a suitable gate valve, the following factors should be considered:
📌 Media Type: Water, oil, gas, or chemical media require different corrosion resistance ratings.
📌 Pressure Rating: Select PN or ANSI rating based on the design pressure.
📌 Temperature Requirements: Stainless steel or alloy steel is recommended for high-temperature environments.
📌 Valve Structure: Soft seals are suitable for conventional water systems, while metal seals are suitable for high-pressure and corrosive media.
📌 Drive Method: Manual, gear, electric, or pneumatic actuators are available to meet diverse automation needs.
