The PRDB series regulator sets an industry standard for both miniaturization and light weight. It is similar to our PRD pressure regulator but with a patent pending valve mechanism, designed to provided high precision/high seal reliability at low flows and at low pressures. It is an excellent choice for low flow gas and pneumatic pressure regulation applications and is particularly useful when space and weight are critical. he PRDB weighs approx. 25 grams in brass and stainless steel.The PRDB non-relieving regulator controls output pressures from 0 to 30 psi and is especially suited to low flow/low pressure regulation such as 1/2 psi. Maximum inlet supply pressure is 500 psig. Both the inlet and outlet ports are tapped 10-32 UNF. Its lightweight design allows for convenient in-line mounting however the 10-32 threaded panel mount option is also offered. Applications include hydrogen fuel cells, medical quipment, instruments, laboratory equipment, ink jet print engines, and semiconductor manufacturing equipment.
