Ball Valve With Relief Hole

The pressure relief hole must connect the valve body cavity to the high pressure side of the ball when it s closed per shell mesc spe 77 170. Ball valves use a metal ball with a hole bored through the center sandwiched between two seats to control flow. Force balances on closed floating ball and gate valves.

As a type of quarter turn valve ball valves can shut off liquid flow from a pipe.

Ball valve with relief hole. Thus these valves are sometimes referred to as downstream sealing. Note that the differential pressure acting across the closure member ball or gate provides a sealing force on the downstream seat at the low pressure side of the valve. Manufacturers situate the ball seats in the valve body. The ball valve is an inexpensive alternative to other valves.

Used in many hydrocarbon process applications ball valves are capable of throttling gases and vapors and are especially useful for low flow situations. These valves are quick opening and provide a very tight closure on. Otherwise from at least a surface level the two valves are identical. When closed the ball can have a lateral movement between the two elastomeric seats.

Look to grainger for a ball valve selection that can handle pressures up to 700 bars and temperatures to 400 f. When closing the valve the media gets trapped in the cavity. A ball valve is a form of quarter turn valve which uses a hollow perforated and pivoting ball to control flow through it. 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.

An attached lever helps allow a spherical port to reopen flow and shut it off again. 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. A standard ball valve which is comprised of a housing a ball featuring a bore through which material may flow a stem controlling the ball position and seals where the ball rests between does not have a visible hole in the ball when the valve is in the closed position.
