ABSTRACT:
A fluid flow valve, particularly of the ball type, with an improved seal and mounting adapter arrangement to permit the valve to be uncoupled in place and swung out or completely removed for repair of maintenance or replacement without disturbing or disconnecting any other portion of the fluid flow system. The valve also includes an improved valve modulating control arrangement which includes frictional locking means coupling the valve control mechanism to the valve member for flow adjustment; but acting to lock the flow adjusting elements and the valve member itself against any significant change in flow control position in response to flow pressures tending to cause an angular shift or rotation of position of the valve element.
