Abstract
A pressure reducing and regulating valve which is operated to move a seal container between an inlet, outlet and vent port in response to fluid pressure. One feature allows the valve to be mounted on a subplate in which both the inlet pressure and the outlet pressure pass through a porting plate which provides a hold down force to compensate for the forces acting to separate the porting plate from the subplate mounting and thus prevent seal extrusion. Another feature of the present invention is the provision of force flow compensating holes which reduce hammering or chattering of the regulating valve.
