Valve dimensions, sizes, and classes can be tailored to the customer’s requirements.

Ball Valve-

Specialityvalve is a reputed Ball Valve manufacturer in India. It is a shut off valve that controls flow of liquid/ gas through a rotary ball which has a bore, by turning it at an angle of 90 degrees so that the medium can flow through or the passage can be blocked. It is used in Oil and Gas Industry, Water and Waste Water treatment plants Industry, Petrochemicals Industry, Nuclear Power Plant Industry and Marine Industry.

Plug Valve-

Specialityvalve is the top Plug Valve Manufacturer in India. It is shaped like a cylinder or cone used to control the flow of fluids by rotating it inside the valve body itself. The plug has a straight through full port opening and can be used in on-off basic moderate throttling, and diverting services. It is used in place of a gate valve when quick operation is required. It is used in Oil and Gas Industry, Water and Waste Water treatment plants Industry, Energy Industry, and Chemical Industry.

Types of Ball Valve:

  • Floating ball valve
  • Fully wielded ball valve
  • Top entry ball valve
  • Trunnion ball valve
  • Jacketed ball valve

Types of Plug Valve:

  • Connection Lift Plug Valve
  • Eccentric Plug Valve
  • Orbit Plug Valve
  • Twin Seal Plug Valve
  • Jacketed Plug Valve
  • Lubricated Plug Valve
  • Non-Lubricated Plug Valve
  • 3 way Plug Valve

Advantages of Ball and Plug Valve:

Ball valve is smaller from a gate valve therefore is light weight. It is used in slurry and clean applications. It is reliable in high temperature and high pressure. Less force is required to actuate the valve. A Plug valve has a simple design with few parts which helps it to be easily open and close for conducting operations. Maintenance can be done at the place of operation for Plug Valve. It has a low-flow resistance and is leak proof.

What is the main difference between Ball and Plug Valve?

A ball valve has a spherical disc and a hollow center. A plug valve is made up of a conical or cylindrical disc with drilled openings. The disc or ball in a ball valve is smaller than the disc or plug in a plug valve. Because of this, a plug valve can provide a tighter shut-off than a ball valve.
