The PRD3 pressure regulator is an excellent choice for gas and pneumatic pressure regulation applications and is particularly useful when space and weight are critical.  Ideal for fluctuating inlet pressures and controls outlet pressures as low as (0 to 30) psig (0 to 2.07) bar. Maintains a stable outlet pressure despite wide swings in the inlet pressure.  The maximum inlet supply pressure is 500 psig. (34.5 bar). Both the inlet and outlet ports are tapped 10-32 UNF. Applications include hydrogen fuel cells, medical equipment, instruments, laboratory equipment, ink jet print engines, and semiconductor manufacturing equipment.
