Drastar 077 Series

Back Pressure Reducing Regulator

The 077 series from Drastar is a back pressure reducing regulator or a pressure relief regulator, designed for use within the water or chemical industry as well as general liquid and gas applications.

The body is all 316L stainless steel, with controlled pressure ranges being 2, 5, 10 or 20 bar (30, 72, 145, 290 PSI).

077 series is available with either 2, 3 or 4 ports and an optional Hastelloy C22 diaphragm.

Drastar’s patented “push and lock type handle” allows easy and stable operation of the low pressure, high flow pressure reducing regulator. “Locking” the pressure is easily done by pushing down the handle and this will prevent any slight change of the pre-set pressure value, typically from vibration on the gas line or ambient changes. Unlocking by pulling back the handle allows the user to make adjustments to the pressure set point.

Drastar’s regulators are oil-free, with all pressure regulators being assembled, cleaned, inspected, and packed in clean-rooms equipped with clean bench, helium detector, particle counter, ultrasonic cleaner, ultrapure water system, vacuum packaging machine.
