077 Series is the back pressure type regulator suitable for water, chemical,liquid, gas,etc. and uses NPT 1/4” pipe exclusively. Regulator body is made of brass or stainless steel 316L and has the wide range of working pressure of 0.3 ~ 20 bar (290 psig) by model. 

Drastar regulators are designed and manufactured for easier operation by equipping with the DRASTAR’s own developed “push and lock” type(patent number 1086199) handle that completely prevents the slight change of pre-set value that can be caused by the vibration from outside or minute vibration at the gas pipeline. you can prevent the slight-changing of pre-set value just by pushing the handle and reset the value freely by drawing the handle. This push and lock system has been created and applied patent for DRASTAR regulators. 

*Caution : Filtering (Gas 7㎛ ~ 15㎛, water 15㎛ ~ 80㎛ ) is a Must for General gas application such as Non-high purity gas. Otherwise, it may cause a breakdown to the regulator. It is strongly recommended to install filter for prolong product life time and enable saving maintenance expense.
