<p>THROTTLING CONTROL VALVE A servo operated throttling control valve for controlling fluid flow in a fluid system such as a pipe line includes a body defining an internal chamber in fluid communication with an inlet and an outlet fabricated in the body. The valve further includes a deformable valve element mounted within the chamber that, in the valve closed position, seats against a valve seat and a rib grill defined in the chamber. The valve element and the body define a control chamber adapted to be coupled to a source of control pressure. The configuration of the body is fluted to accommodate bolt patterns employed in different flange ratings.</p> |
