ABSTRACT:
A pressure reducing valve that is particularly adapted for use with steam at high pressures and temperatures. The valve embodies a main valve seat member that is provided with a valve seat and flow control means disposed downstream of the valve seat to prevent development of zones of excessive velocity of flow through the valve seat and to prevent excessive noise in operation. The position of the main valve spool that controls flow through the main valve seat is controlled by a piston operating in a cylinder and the supply of fluid under pressure to the cylinder is controlled by a pilot valve assembly. The main valve seat member and the main valve spool and the pilot valve assembly can readily be removed from and replaced in the housing of the valve without breaking the connections between the housing and external fluid conduits.
