44-1500 Series Pressure Regulator Pneumatic

44-1500 Series high flow/low pressure regulator controls outlet pressures up to 600 psig / 41 bar. Large area piston provides accurate pressure control and cycle life superior to diaphragm sensed regulators when applied to heavy duty cycling. Features a segregated / captured vent for hydraulic or pneumatic media and is available in two outlet spring ranges. Optional dome or air loaded versions for remote operation or for use with the ER5000 Electropneumatic Controller for automation. Ideal for use in hydraulic and pneumatic testing.
