Built‑in function

B0123HE pneumatic precision pressure regulator reduces high‑pressure compressed‑air source and delivers stable constant‑pressure air supply for field pneumatic positioners and actuators. Built‑in filter element removes impurities from compressed‑air,reducing internal component wear. Manual knob completes convenient on‑site pressure setting. Automatic over‑pressure exhaust protects downstream pneumatic equipment,widely applied for petrochemical,chemical and pulp‑paper plant pneumatic control valve air‑supply loops.

Product Brief

B0123HE belongs to Foxboro legacy pneumatic‑instrument spare‑part family,obsolete original field pressure‑regulating device. Requires clean dry compressed‑air source for normal operation. Widely used for original Foxboro pneumatic‑control‑equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation
