In a pilot operated pressure relief valve, a conduit 11a fluid interconnecting the balancing chamber of the main valve and the pilot valve has a fluid restrictor comprising a flow adaptor 100 including a tubular plug 104 having at least the ball 116 therein, the flow adaptor 100 helps to damp pressure pulsations and therefore cut out chattering of the main valve. An end 120 of a mounting spring 116 and a pin 104 limit movement of the ball(s) 116 in an axial conduit of the flow adaptor &cirf& <IMAGE> |
