Ball Valve Flow Direction Standard

A ball is round so direction does no matter.

Ball valve flow direction standard.

In the case of a ball drilled with a bore in the shape of a t fluid can be directed to more than one location simultaneously. Ball valves are. The opening goes from shut valve through small to large part of the v exposed. A ball valve is a form of quarter turn valve which uses a hollow perforated and pivoting ball to control flow through it.

In the conventional design two identical round seats are fixed or floating on the upstream and downstream side of the ball. Flow direction of conventional ball valves. Changing direction of the ball valve during. If the valve is rotated only 90 degrees a quarter turn in either direction though the handle faces either the front or the back of the valve.

Vertical type l pattern flow three way ball valves have two possible flow paths and two possible off positions. For a vertical type l pattern flow ball valve the bottom port or common port is always open. The shut position 1 4 turn could be in either cw or ccw direction. This check valve uses a ball covering a round opening to separate the first and second port.

This closes the ball valve. The handle on a ball valve opens the valve when it turns the ball to align with the pipe or tube so that it is pointing the same direction as the pipe. It is open when the ball s hole is in line with the flow and closed when it is pivoted 90 degrees by the valve handle. As a rule of thumb the flow direction of ball valves no matter it is designed to floating type or trunnion mounted shall be bidirectional.

In the conventional design two identical round seats are fixed or floating on the upstream and downstream side of the ball. When fluid is drawn in the ball is pushed forward. The preferred flow direction is as far as i have seen in all cases from inside the body against concave innerside of shell ball and out through the regulating v and into the downstream pipeline. When the fluid is pushed back the ball is pressed into the round opening which creates a seal and allows all fluid to flow out the second port in the intended direction.

As a rule of thumb the flow direction of ball valves no matter it is designed to floating type or trunnion mounted shall be bidirectional. A t shape allows one action while an l facilitates another. The double seated ball valve secures a bubble tight shut off with moderate pressure drops and soft seating materials. To accomplish this the bore of the valve s ball is drilled in a particular shape.

The handle lies flat in alignment with the flow when open and is perpendicular to it when closed making for easy visual confirmation of the valve s status. If a valve must be installed in a certain direction is should have an arrow cast into the body showing the direction of flow. The valve handle can also turn the ball so that the bore is at a right angle or 90 degrees to the flow.

Turning the valve handle 180 degrees a half turn diverts flow either to the left or to the right see the previous images. Flow characteristics 108 kitz ball valves kitz ball valves are manufactured under the same quality system designed according to iso 9001 no matter where they are produced.
