Description Piston-operated regulator with balanced valve design and high-relief flow. Features include a transparent, pressure-calibrated, non-rising adjusting dial, which can be mounted in any position to ensure the dial face is always visible. Pressure setting in steps is possible. Media Compressed air Supply pressure Max. 21 bar, minimum 1 bar above outlet pressure Air consumption R21/R31/R41: Max. 1.4 l/min depending on outlet pressure Adjustment The full secondary pressure range can be adjusted with less than a 270° turn, proportional to the handwheel, with a scale in bar or psi. This is advantageous when frequent changes in secondary pressure are required. Relieving function Relieving Gauge port G1/4 on both sides of the body Mounting position Any Temperature range 0°C to 65°C / 32°F to 149°F Material Body: Zinc die-cast Piston: Acetal O-ring: NBR/Buna-N Valve seat: Acetal, brass, and NBR/Buna-N
