Class Information
Number: 137/852
Name: Fluid handling > Line condition change responsive valves > Direct response valves (i.e., check valve type) > Resilient material valve > With valve member flexing about securement
Description: Valve wherein a portion of the resilient member is fixed to a substantially rigid mounting means about which at least part of the remainder of the resilient member bends or distorts towards or away from contact with a valve seat with which the resilient member coacts to produce a desired valving action upon variations in fluid pressure.
