PRO-50 Series regulators are designed to be a compact, lightweight option for providing controlled pressures to instrumentation. Generally used to constantly control supply pressure to pneumatic and electro-pneumatic instrumentation, these direct-operated regulators are rugged enough to be used in most air or gas applications.
Engineered to provide clean supply pressure to meet the accuracy, repeatability and hysteresis demands of digital instrumentation, the PRO-50 is also well suited to supply local pneumatic instrumentation.
