FISHER 67CFR-235
Parameters / Specifications
Model: 67CFR-235
Series: Fisher 67C Series (Instrument Supply Regulators)
Construction: Filtered regulator with internal relief (i.e., integral filter and soft-seat internal relief valve)
Body material: Aluminum (standard for 67C series non-CS version)
End connections: ¼ inch NPT (inlet & outlet)
Maximum inlet (body rating) pressure: 250 psig (≈17.2 bar) for standard models.
Maximum emergency outlet pressure (i.e., the relief valve will relieve when downstream exceeds setpoint by this margin): 50 psig (≈3.4 bar) above the outlet setting.
Typical outlet (regulated) pressure spring range for the “235” variant: likely 0–35 psig (≈0–2.4 bar) (many order-codes in the 200-series use 0-35 psig)
Filter: Integral, standard rating about 5 microns for polyethylene filter element
Temperature capability (depending on elastomer / diaphragm / filter media):
Nitrile (NBR): –40 °F to +180 °F (≈ –40 °C to +82 °C)
Fluoroelastomer (FKM): 0 °F to +300 °F (≈ –18 °C to +149 °C)
Silicone (VMQ diaphragm + low-temp bolting): –60 °F to +180 °F (≈ –51 °C to +82 °C)
Media: Air or compatible gases (must confirm elastomer/filter compatibility for specific gas)
Typical weight (for ¼ in NPT aluminum body version): about ~1 lb (≈0.5 kg)
Typical applications: Instrument air supply regulators for pneumatic controllers, actuators, panel mount regulators, air chucks, spray guns, etc.
