Class Information
Number: 137/614.04
Name: Fluid handling > Systems > Flow path with serial valves and/or closures > Separable flow path section, valve or closure in each > Each valve and/or closure operated by coupling motion > Linear motion of flow path sections operates both > Valves actuate each other
Description: Systems in which the force which moves the valves, flow controllers, or closures is transmitted from one to the other and vice versa.
