Kinvalve Stainless Steel Gate Valve to Skyrocket Your Business
Kinvalve stainless steel gate valve is a very important product line. As a leading stainless steel gate valve manufacturer and supplier, our full capacity on stainless steel gate valves will provide one-stop solution for your specifications.
At Kinvalve, cast stainless steel gate valve is the most common type, covered by the API 603 specifications. Kinvalve cast stainless steel gate valves are available in sizes about 1/2 inch and up to 12 inches.
Our stainless steel gate valves provide full flow with minimal pressure drop. In the case of stainless steel gate valve, all stainless construction extends it a wide range of industry and media uses including water, gas, oil and some acids.
Stainless Steel Flanged Gate Valve
At Kinvalve, stainless steel flanged gate valve is always a rising stem design coming with solid wedge type or flex wedge type discs. It is simple for your use, installation and maintenance.
As a qualified stainless steel gate valve manufacturer with over 18-year experience, Kinvalve can provide a full range of stainless steel flanged gate valves in accordance with ANSI/API, JIS and DIN standards.
Our stainless steel flanged gate valves feature flat face end connections as standard for installation and accessibility.
Outside screw and yoke (OS&Y) gate valves are recommended when positive shutoff and a quick visual indicator of open/closed position is required. The OS&Y configuration protects the stem threads from contact with the media.
Threaded Stainless Steel Gate Valve
Kinvalve threaded stainless steel gate valve is designed to ANSI B16.34 and qualified BSP or NPT threaded female ends with an aluminum or cast iron handle.
This threaded stainless steel gate valve is tested and inspected according to API598 for your quality assurance.

What is a Stainless Steel Gate Valve?
A stainless steel gate valve is a type of pipe fitting that is used to control the flow of fluids. It is equipped with a flap that works by forming a barrier that can be lifted and lowered to start and block the passage of water through a system.
The SS gate valve is made out of stainless steel that is not only resistant to corrosion but will also provide you with a long service life.
Advantages of Gate Valve made of Stainless Steel
There are numerous advantages to using valves that are designed from stainless steel. These benefits include;
- Stainless steel gate valves have an increased resistance to corrosion. This attribute makes it suitable for controlling the flow of all types of fluid including corrosive substances.
- Valves made from stainless steel are very sturdy and durable and can therefore be used for a long time without needing to replace the valve
- Stainless steel has a high tolerance to high temperatures. Gate valves fashioned from stainless steel can therefore be utilized even in environments where they will be subjected to high temperatures.
- It is very easy and simple to clean the stainless steel gate valves
- Stainless steel does not encourage the growth of microbes, SS gate valves can therefore be used in food processing as well.
- Stainless steel gate valves cannot easily interfere with the flow of liquid.
Key Features of SS Gate Valves
There are several features incorporated in stainless steel gate valves. The key features include
- SS gate valves have a pressure rating of 600psi which is a relatively high
- There are different thread types such as straight and tapered threads included in the BSPP, BSPT, or NPT thread types.
- Is equipped with a non-rising stem with a wedge stop. It also has rolled threads to increase the strength
- Are equipped with an integral seat
- Has an extensive temperature range of 20°C to 180°C making it suitable for controlling the flow of hot fluids.
- Stainless steel gate valves have corrosion-resistant features ensuring that the gate valve does not get eaten into by corrosive fluid
- SS gate valves come with a permanent integral wedge nut. This nut is responsible for stopping vibrations ensuring the gate valve can function properly for a long time.
- Some include EPDM rubber which is approved even for tap water.
Best Stainless Steel Grade for Gate Valve Fabrication
Different grades of stainless steel are used in the fabrication of gate valves. The different grades have different characteristics making them suitable for different reasons. The different grades used include;
- Grade 301; It is resistant to corrosion and can easily be forged
- Grade 304; Has a higher resistance to corrosion even more than grade 301
- Grade 305; This grade of stainless steel has an appealing appearance and is very durable
- Grade 316; Is resistant to corrosion but is affected by increased saline levels that corrode the metal
- Grade 202; It is cheaper to purchase but is of a lesser quality and is less resistant to corrosion
- Grade CF8; Has an increased resistance to cavitation making it a suitable material for transporting fluids
- Grade CF8M; This grade has an increased resistance to corrosion more than grade CF8. It is also resistant to pitting caused by chlorides.
Stainless Steel Gate Valve Applications
Stainless steel valves are versatile fittings that can be used for a broad range of applications. The material they are made from makes them resistant to corrosion and high temperatures. It also makes them durable making them great for a variety of uses. They can be used to control the movement of fluid in the following industries;
- Food and Beverage
