Abstract: The valve is one which, by preference, has a Teflon liner forming a self-lubricating seal within which the hollow valving member rotates; and included in the structure is a flow regulator in the form of a replaceable or adjustable orifice sleeve which normally is embodied wholly within the axial bore of the hollow valving member.
