Product Description:
The Norgren B38P series is a range of high flow stainless steel filter regulators designed for use in corrosive environments, combining filtration and precision pressure regulation in a single integrated unit. These filter regulators are specifically engineered for applications where standard materials are not suitable, including marine environments, oil and gas production, chemical and food processing, and medical analysis equipment. The metallic parts meet NACE Standard MR-01-75, the recognised oil-field recommendation for resistance to sulphide stress cracking common in well-head and other corrosive environments.
The B38P series features a 316 stainless steel body, bowl, bonnet, and adjusting screw, providing excellent resistance to salt spray, acids, alkalis, and petrochemical corrosion. The filter regulator operates with a maximum inlet pressure of 31 bar (449 psi) for manual drain versions and 17 bar (246 psi) for automatic drain versions, with an outlet pressure range of 0.5 to 10 bar or 0.5 to 7 bar depending on the selected model. The integrated 5 µm, 25 µm, or 40 µm filter element removes solid particles and condensate from the compressed air supply, protecting downstream equipment and ensuring reliable operation.
The B38P-244-B1MA model features 1/4" ports with a flow rate of 40 dm³/s, while the B38P-344-B1MA features 3/8" ports with the same flow rate. Both models include manual drain and relieving design, with a panel mounting nut for convenient installation. The FKM (FPM) or NBR elastomer options allow for operating temperature ranges of -20°C to +80°C (FKM) or -40°C to +80°C (NBR), making these units suitable for demanding industrial and offshore environments.
The filter regulator is also available with ATEX certification for use in hazardous areas, and the design meets certain requirements of Heavy‑Duty Specifications MIL-S-901C (Navy) for shock resistance and MIL-STD-167-1 for mechanical vibrations of shipboard equipment.
