Female threaded one piece ball valve

Female threaded one piece ball valve

Female threaded one piece ball valve is a kind of one piece ball valve that is almost always reduced bore, and is relatively inexpensive, whose connection part uses female thread. Female threaded one piece ball valve is a kind of high integrity valve. The number of leak paths to atmosphere is reduced to a minimum. Standard valves have a single body casting which can include the bonnet. Small valves with screwed connections can be manufactured by machining from a solid forging: internal access being gained through the bonnet and bottom flange when fitted.

A thread is a helical structure used to convert between rotational and linear movement. A thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter one called a tapered thread. Male and female, can be described as external and internal. For example, a screw has male threads, while its matching hole has female threads. This property is called gender.Internal and external threads illustrated using a common nut and bolt. The screw and nut pair can be used to convert torque into linear force. As the screw (or bolt) is rotated, the screw moves along its axis through the fixed nut, or the non-rotating nut moves along the lead-screw.
