FAQs
Install using the panel mounting options noted for 07 Series hardware. Utilize the 07 Series Neck Mounting Bracket and panel nut accessories to secure the regulator, ensuring the unit is upright and accessible for adjustment. Verify the 1/4 PTF inlet and 1/8 PTF gauge ports align with your manifold and monitoring lines.
The unit features a 1/4 PTF port, automatic drain, and a 5 μm filter element. Outlet pressure is adjustable from 0.3 to 8.5 bar (4 to 123 psi) with a maximum inlet pressure of 20 bar. It provides a relieving regulator configuration and a flow of approximately 7 dm3/sec (15 scfm).
Yes. The body is stainless steel (1.4104/316) with metallic parts meeting NACE recommendations, making it well suited for corrosion-prone environments such as marine and petro-chemical facilities, as well as medical and food-processing sectors where hygiene and reliability are critical.
The B05-233-A1LA includes an automatic drain to remove condensate without manual intervention. Regular inspection of the filter element (5 μm) and ensuring the drain remains clear are usually sufficient. If uptime is critical, pair the unit with the 3820-08 B05 service kit for periodic maintenance.
The model is specified as without a gauge, but it supports a 1/8 PTF gauge port for monitoring. Accessories listed include 5726-04 Filter Element and 3820-08 B05 Service Kits, which can support maintenance and element replacement as part of a preventive maintenance plan.
