Product DescriptionProduct ParametersProduct DescriptionReliable Full Open/Close ControlGate valves are specifically engineered for reliable on/off service in pipeline systems, utilizing a linear motion mechanism to raise or lower a solid wedge, parallel disc, or flexible gate into the path of flow. This fundamental design ensures a tight, bubble-tight seal when fully closed, effectively isolating sections of a system for maintenance or safety, and permits unobstructed, straight-through flow with minimal pressure drop when fully open. Their full port design, where the bore diameter matches the pipeline, minimizes turbulence and erosion, making them exceptionally efficient for applications where flow resistance must be avoided. This combination of positive shut-off and low flow resistance makes them the preferred choice for isolation duties in a vast array of industries, including oil and gas, power generation, and water distribution, where they are often left in either a fully open or fully closed position for extended periods.Bi-Directional Flow & Low Flow ResistanceSuitable for High-Pressure & High-Temperature ApplicationsThey offer unimpeded, straight-through flow in both directions, minimizing turbulence and pressure loss for highly efficient system operation.Constructed from robust materials like stainless steel or carbon steel, they are built to withstand extreme pressures and temperatures in demanding environments.Durability & Long Service Life,Variety of Materials & Standards,Multiple Actuation OptionsTheir simple yet robust design, often with metal-to-metal sealing, ensures exceptional durability and a long operational lifespan, reducing replacement costs.Available in various materials (WCB, SS304, SS316) and compliant with international standards (API, ANSI, DIN), making them versatile for water, oil, gas, and chemical services.They can be operated manually via a handwheel or lever, or automated with gear, electric, pneumatic, or hydraulic actuators for remote control and integration into complex systems.Key Components & Design:Why Stainless Steel?Operation:Body & Bonnet: Manufactured from various grades of stainless steel (e.g., CF8/SS304, CF8M/SS316). The bonnet is often bolted to the body for easy maintenance.Disc (or Gate): The sealing element that moves up and down to block or permit flow. Common designs include solid wedge, flexible wedge, and split wedge.Stem: The rod that connects the actuator (handwheel or gear) to the disc. It can be a rising stem (visible and indicates valve position) or a non-rising stem.Seat: The surface against which the disc seals. Seats can be integral (part of the body) or reinforced with welded seats for enhanced durability.Stainless steel is the preferred material for corrosive, high-purity, or extreme temperature applications due to its:Excellent Corrosion Resistance: Withstands water, chemicals, steam, acids, and other aggressive media.High Strength & Durability: Suitable for high-pressure and high-temperature services.Hygienic Properties: Easy to clean and sterilize, making it ideal for food, beverage, and pharmaceutical industries.Long Service Life: Highly resistant to pitting, cracking, and oxidation.The valve is operated by rotating a handwheel or a gearbox. This rotation moves the stem and the gate linearly, either lifting the gate entirely out of the flow path (full open) or lowering it to seal against the seats (full closed).Provides a tight seal with minimal pressure drop when fully open.Robust construction suitable for high-pressure/temperature services.Excellent corrosion resistance extends valve life.Bi-directional flow capability.Connection Types: International Standards:Primary Applications:Flanged Ends: The most common type for piping systems (e.g., ANSI, DIN, JIS standards).Screwed (Threaded) Ends: For smaller pipe sizes.Butt-Weld Ends: For permanent, high-integrity connections in critical services.Stainless steel gate valves are manufactured to meet global standards ensuring quality, safety, and interoperability:API 600: Standard for bolted bonnet steel gate valves for petroleum and natural gas industries.ASME/ANSI B16.34: Standard for valve pressure-temperature ratings.BS / EN Standards: European norms (e.g., DIN, GOST).Face-to-Face Dimensions: ASME B16.10, EN 558.These valves are critical in industries where corrosion resistance and leak-tight shut-off are paramount:Oil & Gas: Pipeline isolation, refinery services.Chemical & Petrochemical: Handling corrosive acids, solvents, and chemicals.Power Generation: Steam, feedwater, and cooling water lines.Water Treatment: Potable water, wastewater, and desalination plants.Marine & Shipbuilding: Seawater systems due to excellent saltwater resistance.Food, Beverage, & Pharmaceutical: For hygienic processing lines.Packaging & Shippingcustomized PackaqingSolutionsWe offer customized packaging based on the valve type, size, and destination requirements.

How many countries have you exported to?We've shipped our stainless steel pipes to more than 30 countries—from Egypt to the Philippines! Think of us as your global piping pen pals.2. What's your product range? Ever wished for a place that sells everything piping-related? You've found it! We offer ONE-STOP service for seamless pipes, tubes, fittings, flanges, valves…you name it. Consider us your "Stainless Steel Supermarket" .3. What's your delivery time?Good things take time—like pizza , but with more steel! Generally between 15–50 days, depending on how much you order and where you are. Note: seamless & welded pipes require a little extra love (and time) compared to fittings.4. Can you provide OEM service? Absolutely! We love custom requests. Want your logo on a valve? Fancy a flanged flange? Let's talk. We're basically the tattoo artists of steel .5. Can we visit your factory?Please do! We'll roll out the (stainless) red carpet for you. Just share your schedule, and our A-team will make sure you leave impressed—and maybe with a new favorite pipe.6. What's the difference between Stainless Steel and Aluminum?Ah, the classic heavyweight vs. lightweight showdown! Stainless Steel: Strong, corrosion-resistant, handles heat like a champ , and won't quit under pressure. Perfect when you need things tough and timeless. Aluminum: Light, cost-friendly, a thermal conductivity superstar , and easier to shape. But it gets soft around 400°C and isn't as strong as steel. So… picking between them? It's like choosing between a marathon runner and a powerlifter . Tell us your goal—we'll help you choose!Looking for more? Looking for more?
