Class Information
Number: 137/503
Name: Fluid handling > Line condition change responsive valves > With separate connected fluid reactor surface > Responsive to change in rate of fluid flow > Expansible chamber subject to differential pressures > Pressures across flow line valve
Description: Apparatus in which the pressures to which the movable reaction member is subject are taken on opposite sides of the throttle valve which is operated by the reaction member and which valve regulates the fluid flow.
