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.
