Specifications / Parameters Below are the key specifications and operating parameters for the 67CFR-225 version: Body material: Aluminum (alloy) Body size & end connections: ¼ inch NPT (inlet & outlet) Maximum inlet pressure (body rating): 250 psig (≈17.2 bar) Maximum emergency outlet pressure: 50 psig (≈3.4 bar) over the set outlet pressure Outlet (regulated) pressure range: 0-60 psig (≈0-4.1 bar) for this version (0-60 psi spring range) Filter: Integral filter (e.g., ~5 micron polyethylene standard) Internal relief: Yes — soft-seat internal relief valve integrated Temperature capabilities (depending on elastomer material): Nitrile (NBR): –40 °F to 180 °F (≈ –40 °C to 82 °C) Fluorocarbon (FKM): 0 °F to 300 °F (≈ –18 °C to 149 °C) Silicone (VMQ) with low temperature bolting: –60 °F to 180 °F (≈ –51 °C to 82 °C) Approximate weight: ~1 lb (~0.5 kg) for standard 67C/67CFR body Media: Air or compatible gases (depending on materials of construction) Typical applications: Instrument supply regulators for pneumatic/electropneumatic controllers, valve positioners, etc. Construction notes: With filter and relief means particulates are removed and downstream over-pressure can be relieved automatically when downstream exceeds the setpoint plus relief margin.
