The 44-1100 Series regulators are piston-sensed pressure regulators designed for high outlet pressures and low flow rates with venting capability. With control pressure ranges from 414 to 690 bar (6,000–10,000 psig), low torque adjustment, and a large handwheel, they are available with several pressure range options. Ideal for use in Ground Support Equipment (GSE), back pressure panels, aircraft refueling carts, research and development laboratories, and calibration systems.
