Example) 90-AR30K-03B-1NR . With the backflow function it incorporates a mechanism to exhaust the air pressure in the outlet side reliably and quickly. Example 2) When the air supply is cut off and releasing the inlet pressure to the atmosphere, the residual pressure release of the outlet side can be ensured for a safety purpose. Example 1) When the pressure in the rear and the front of the cylinder differs: 90 Regulator 90-AR30/90-AR40 Regulator with Backflow Function 90-AR25K to 90-AR60K Note 1) Assembly of a bracket and set nuts.
