Pressure reducing valve with pressure gage in handle
A gage-in-handle type pressure reducing valve wherein a feedback chamber and a pressure gage are communicated with each other through a communicating passage between a feedback member and a pressure gage guide without using a pressure introducing hole in a valve body wall or a bonnet wall, Resilient Seated Gate Valvesand which is capable of minimizing friction occurring in a mechanism for converting the rotation of a handle into an axial movement of a pressure regulating spring retainer. A pressure gage guide is connected to the pressure gage. The feedback member is formed with a communicating hole communicating with the feedback chamber. Reducing ValvesThe communicating hole is communicated with the pressure gage guide through a communicating line. A pressure regulating nut is rotatably supported in a bonnet. The pressure regulating spring retainer is supported in the bonnet so as to be axially movable but unable to rotate. Rotation of the handle causes the pressure regulating nut to rotate, and this, in turn, causes the pressure regulating spring retainer to move axially.
