What is a Gate Valve?
A gate valve is a linear motion valve that uses a flat or wedge-shaped gate to start or stop the flow of fluid. It’s not about throttling – it’s about full bore or zero flow. You choose a gate valve when your process demands minimal pressure drop, tight shut-off, and reliability over time.
What does this mean for you? · Efficiency · Less Maintenance · Fewer Shutdowns · More Control
When you’re sourcing industrial valves for critical flow control, you need more than just a product – you need certainty. As a professional in your industry, you understand how crucial reliability, compatibility, and performance are to your operations. That’s where TOT Valve comes in. We are your trusted Chinese manufacturer specializing in API, ASTM, ANSI, JIS, DIN, GOST, and CE standard gate valves engineered for consistent performance under the toughest conditions.
TOT Gate Valves aren’t just designed. They’re built around you – your industry, your specifications, and your operational challenges. Whether you’re dealing with high-pressure pipelines, abrasive media, corrosive environments, or extreme temperatures, you’ll find a solution in our comprehensive gate valve lineup.
Be careful when choosing a new valve supplier, the disappointment of poor quality can last much longer than the joy of a low price!

Compare Gate Valves vs. Other Valve Types
| Valve Type | On/Off Control | Throttling | Flow Resistance | Application Fit |
| Gate Valve |  Best |  Not ideal |  Low | Clean isolation |
| Globe Valve | Good | Excellent |  Higher | Flow control |
| Ball Valve | Excellent |  Limited | Very Low | Fast shut-off |
| Butterfly Valve | Good | Moderate | Medium | Compact systems |
Tip: Use gate valves where full open/full close is critical, and pressure drop needs to be minimal.
TOT Valve Manufacturing and Quality Control
At TOT Valve, our manufacturing process is carefully designed to ensure the production of the highest quality industrial valves.
Material Preparation: We use high-grade raw materials such as high-quality SS 304/SS 316L/SS316Ti stainless steel, brass and ceramics.
Valve Body Processing: We have our own foundry, where we cast the raw materials precisely.
Valve assembly: Assemble the valve body, valve stem, valve seat, seals and other parts. We generally use a combination of mechanical processing and manual assembly.
Valve Testing: TOT Valve has a strict quality inspection system and tests the assembled valves, including size, leak plugging, corrosion resistance, pressure resistance and other tests.
Cleaning and Surface treatment: Clean the assembled valves to remove surface impurities and stains, or perform surface treatments such as polishing, sandblasting, and spraying.
Packaging and Storage: Pack the valves, mark and record them, and store them in the designated warehouse.
By adhering to these meticulous manufacturing processes, TOT ensures that every industrial valve produced meets the highest standards of quality and performance. Our commitment to excellence in every step of production reflects our dedication to providing quality products that our customers can trust.
