Fluorocarbon Pintle: A special elastomeric pintle used where elements in the supply air, such as flame retardant synthetic lubricants, are particularly destructive to ordinary pintle material. Non Relieving: Used in applications where it is desirable to relieve pressure downstream of the regulator, for some constant flow applications, and where the gas flowing through the regulator must not escape at the regulator. Non-relieving regulators should not be used for low or no flow applications. Corrosive Resistant Epoxy finish: An epoxy paint applied to the body and bonnet of the regulator exterior surfaces to provide increased corrosion resistance. Mounting Bracket: Steel (dichromate finish) bracket for side mounting. P/N: 607-000-057 Knob: Option to replace the square head pressure adjusting screw. Tapped Vent: Allows installation of plumbing to capture exhaust air. Pressure Gauge: Dual scale 2 in. (50.8 mm) gauges. Ranges include 0-30 psig (0-200 kPa), 0-60 psig (0-400 kPa), 0-100 psig (0-700 kPa) and 0-160 psig (0-1100 kPa). When specified with regulator, the correct range will be supplied. For NPT versions only. Tamper Resistant Cover: An aluminum tubular cover placed over a slotted head adjusting screw and screwed onto the bonnet of the regulator with a wrench. Prevents ordinary hand adjustments. Soft Relief Seat: Used in applications where it is desirable to reduce the standard bleed rate from 6 SCFH [0.17 m3hr] to less than 0.1 SCFH [0.003 m3hr]. Fluorocarbon Diaphragm: Diaphragm as well as all seals are made of fluorocarbon elastomer to prevent deterioration from elements in the air supply, such as flame retardant synthetic lubricants normally destructive to standard Nitrile material.
