Masoneilan 525-526 Series Pressure Reducing, Back Pressure & Differential Pressure Regulators
The Model 525 and 526 pressure regulators are engineered for pairing with the 10900‑Series spring‑diaphragm actuators, covering pressure‑reducing, back‑pressure and differential‑pressure control duties.
Masoneilan 535H-536H Pressure Regulator for Reducing, Back Pressure and Differential Service
Baker‑Hughes Masoneilan 535H and 536H pressure regulators provide accurate pressure reduction for air, liquids, saturated and superheated steam. Available in sizes ¾” through 2”, with full‑area or reduced trim, they are suited for small‑to‑medium flow applications requiring Class IV or VI shut‑off per IEC 60534‑4 / ANSI/FCI 70.2. For service temperatures above the diaphragm temperature limit, fit the actuator beneath the valve‑body centre‑line. A condensate barrier in the sensing line and actuator case protects the diaphragm. Alternative mounting requires an independent condensate‑barrier assembly. Contact the factory for additional information.
Masoneilan 172 Series Spring loaded, Direct Operated, Pressure Reducing Regulator
The Masoneilan 172‑Series spring‑loaded direct‑operated pressure‑reducing regulators provide reliable outlet‑pressure control. Available in ½”‑2” (DN15‑DN50), the valves support a wide variety of end connections. The bolted‑flange configuration enables custom face‑to‑face dimensions for easy replacement of legacy equipment. Compact and rugged, they perform well under severe service and feature simple installation and maintenance.
Masoneilan 173 Series Spring Loaded, Direct-Operated Back-Pressure Regulator
Masoneilan 173 Series direct‑acting spring regulators serve steam, gas and liquid applications for pressure relief and back‑pressure control. Available in ½”–2” (DN15–DN50), they ensure durable, continuous industrial service.
Masoneilan 174 Series Spring Loaded, Direct-Operated Reducing or Back-Pressure Regulator
The Masoneilan 174‑Series spring‑loaded direct‑operated regulators perform pressure‑reducing or pressure‑relief control for diverse industrial applications. Equipped with a large‑size diaphragm for precise low‑pressure regulation and a lever‑type mechanism for reliable tight shut‑off, they are offered in ½”‑1‑½” (DN15‑DN40) with a maximum inlet pressure of 145 psig (10 barg). Its simple‑design construction ensures flexible deployment, easy installation and maintenance.
