Model HP 750 series is a ultra high pressure, ultra high flow dome loaded regulator. The key to the performance of this regulator is the servo-dome load technology where the pilot light and dome regulator are integrated into one body with no external tubing. The servo-dome load features allow the regulator to supply ultra high flow rates with straight line pressure regulation. Automatically adjusts the regulator as the cylinder pressure declines providing steady outlet pressure and flow rate without user adjustment. Typical applications include ultra high flow laser assist gases, pressure transfer, blanketing and ultra high flow manifolds and lasers. Features include brass barstck body, bonnet and dual scale gauges, a one-piece encapsulated seat design with 10 micron filtration and PTFE Teflon® seat and tamper proof, self-reseating internal safety valve.
