What is a Ball Valve?
The ball valve is a type of valve with a spherical perforated barrier that controls the hydraulic flow. A ball valve is normally opened or closed by spinning it 90 degrees around its axis. One of the most common types of valves is this one. In addition to liquid applications, ball valves can also be used for gas applications. During their service life, they provide dependable sealing and are very popular in the chemical, petrochemical, and oil and gas industries. Vacuum and freezing applications can also be accommodated by ball valves. We are the leading single piece ball valve manufacturer in India.
How does it work?
The ball within the valve has a hole through which the flow may conveniently pass if the two ends of the valve are properly integrated. When the hole is perpendicular to the ends of the device, the valve is completely shut. If the hole is in any other position, the flow is completely or partially halted.
Some of the types of Valves:
One-Piece Valve:
In a single piece ball valve, the inner elements are contained within a single-piece cast body. There is no longer a possibility of liquid overflowing from the valve. One-piece ball valves have a smaller diameter and are less expensive. Welded one-piece ball valves are more common, but they can’t be dismantled or repaired once they’ve been damaged; as a result, they’re used in situations where molecule formation is minimal and disinfection isn’t an issue. In contrast, screwed one-piece ball valves can be cleaned, adjusted, and repaired, whereas damaging them requires special tools.
Two-piece valve:
A two-piece plan is used to supplement a single-piece plan for reduced bore and FB valves with diameters greater than 6″. As part of the two-piece design, the body stud holds the ball in place. There may be an acceptable design at this point, whether it is a full bore or a reduced bore.
Three-piece valves:
Two-bolt connections hold the two ends of a three-piece ball valve together. The housing for the valve’s internal components is attached to the two ends by bolts. There is a threaded or welded connection at each end of the main pipe.
Top Entry Valves:
The internals of a top entrance ball valve can be accessed by simply removing the bonnet. As a result, in-line maintenance is possible without removing the ball valve from the main line.
Full Port Ball Valve:
A full port ball valve has a larger-than-usual ball with the goal of keeping the opening of the ball equal to the opening of the pipeline. This reduces the possibility of grating misfortune. There is no limit to the stream, but there is a larger valve.
Standard Port Valves:
A standard port ball valve differs from a full port ball valve in that it has a smaller port and ball. Due to the smaller pipe size, it has a lower flow and is comparatively less expensive. Although they have a larger pressure drop than other ball valve varieties, they are less expensive.
Trunnion Ball Valves:
Larger, higher-pressure valves often use this type, which anchors the ball at the top and bottom with a mechanical mechanism.
Vented Ball Valve:
In construction and operation, a vented ball valve is similar to a regular ball valve, with the exception that it has tiny holes punched into its side. When the valve is closed, the orifice points to the outflow side. By venting trapped gases inside the valve, the pierced hole prevents leakage, valve failure, and explosion.
Reduced Bore Valve:
When a bore diameter is reduced by a pipe size, it is smaller than the (connection) pipe diameter. The real decrease is determined by the agreement between the manufacturer and the customer. It is more common to find ball valves with a reduced bore than those with a full bore. Typically, they are used in situations where product flow rates and turbulence aren’t an issue, and particle build-up is unlikely.
