ABSTRACT:
A pneumatically controlled assembly for the no-bleed regulation of the pressure of a gas as it flows in a pressurized line and including two balance valves that are set to respond to variations in pressure in conjunction with a controller valve so as to effectively regulate and maintain the pressure of the gas in the pressurized line. The balance valves are adjusted to maintain a gas tight seal, to open only in the situation when the gas pressure in the line is over the set amount desired, and to automatically close when the pressure in the line has returned to the desired level. The balance valves act in the situation where the pressure in the line changes, either over or under the set pressure. This is accomplished through a sensor mechanism such as a diaphragm. The diaphragm is set to respond to the desired pressure changes and communicates the pressure changes in the line by means, for example, of deflecting a spring. The sensor communicates the pressure change to one or both balance valves.
