The problem: 
To design a simple, reliable 
control of gases or liquids. 
The solution: 
Two porting rings, one within the other, control 
flow by using seal buttons as the sliding valve closers. 
Multiporting within the rings allows close control of 
the gas or liquid flow by the slight rotation of the 
outer porting ring. 
How it's done: 
The outer or actuating ring contains plastic seal 
buttons that are located immediately adjacent to the 
ports and are flush with the outside surface of the 
inner porting ring. The seal buttons ride against a 
plastic coated surface of the inner ring, and are main-
tained by steel spring washers and the fuel flow pres-
sure acting from behind them.
Actuator 
outer ring determine the amount of flow through the 
valve. 
The outer ring is hydraulically actuated by the gas 
or liquid of the operating medium and is controlled by 
a small solenoid valve. 
Notes: 
1. Under test to pressures of 1,000 psi, this valve de-
livered up to 371 gpm with no leakage in any posi-
tion through 275 cycles.
