Different type of vales and their features

Ball Control Valve was first developed in 1967, and since then thousands of valves have been installed in:

  • Pulp and paper mills
  • Cement and steel companies
  • Coal and mining processing plants
  • Slip plants
  • Hardened water treatment plants
  • Chemical and pharmaceutical industry
  • Refining, gas and thermal power plants

Due to its self-draining, excellent regulation behavior, very good resistance to abrasion, easy to automate and install inline and its high tightness in critical conditions, SS 316 Bolts is recommended for:

 

Cellulose and paper pulp

  • Suspensions with abrasive liquids such as iron ore, slip, whitewash, ash, sand, etc.
  • Acidic and caustic solutions
  • Air, oxygen, methane, nitrogen, ammonia.
  • Oils and hard waters
  • Regulation of high flow rates and abrasive fluids

Different types of valves

Ball and butterfly valves from SS Ball Valve manufacturer in India are popular because of their relatively low cost, long service life, and reliability. However, there are some differences to help determine which one to choose from.

 

Ball valves

A valve is (in simple terms) a ball with a hole through it. The valve from SS fasteners manufacturers in india must be rotated to different positions to either completely block, partially or fully open it to the flow line through the valve.

 

Advantages of the ball valve include a good seal, or do not leak when fully closed. A ball valve will rotate regardless of the pressure on the inlet side. If the diameter of the hole through the device is as large or larger than the internal diameter of the pipe it supplies, the ball valve will not exhibit a pressure drop or limiting when fully open.

 

Butterfly valves

A butterfly valve is a disc mounted on a rotating shaft. When fully closed, the disc totally blocks the line. When fully open, the disc is parallel to the flow of gas or liquid.

 

One of the benefits of using this type of valves is that they are comparatively reasonably priced to build and maintain. They are the most common valve for systems with large volumes of water such as municipal water service. They can be used for dirty water applications such as drainage or controlling river water.

 

This type of valve disc remains in the flow line when completely open, so there will for all time be a pressure drop all across the butterfly valve. Also, if the pressure difference across the butterfly valve is greater, it may be not easy to open it. Some applications require a bypass valve to equalize the pressure difference before the butterfly valve can operate.

 

Differences

Butterfly valves are less expensive and generally lighter than other types of valves. A large diameter pipeline butterfly valve is much smaller than its equivalent ball valve.

 

Butterfly valves do not seal completely like ball valves and are rarely used in gas flow control. Ball valves provide a reliable seal.

 

At high pressures, the ball valve will provide superior shear characteristics since they have no trouble turning or do not need a pressure balancing scheme.
