Baker‑Hughes Masoneilan™ 174‑Series are spring‑loaded, direct‑acting regulators built for pressure‑reducing or pressure‑relief duties across a wide spectrum of industrial services. Its large‑area diaphragm delivers enhanced control accuracy under low‑pressure set‑point conditions, while the lever‑drive mechanism achieves exceptional tight shut‑off performance. These regulators are available in body sizes from ½” up to 1‑½” (DN15‑DN40), with a maximum allowable inlet pressure of 145 psig (10 barg). Featuring a streamlined, simple‑built configuration, the valve offers high application flexibility, straightforward installation and convenient routine maintenance.
