Type 51 High-Performance Low-Cost Precision Air Regulator offers a high-performance in a compact, low-cost package, offering output pressure ranges to 100 psig; 6.9 BAR (120 psig; 8.3 BAR in T-51FR Corrosive Tec & T51FRWT). Maximum supply pressure is 250 psi (17.3 BAR). Materials of construction for standard Type 51 Series Regulators: Die cast aluminum for the body and dripwell; glass-reinforced thermoplastic polyester for the bonnet; acetal resin for the internals; BUNA-N for the diaphragm, gaskets and O-ring, fluorocarbon for the pintle seat, and aluminum for the drain valve (plated steel handle). Materials of construction for Corrosive Tec Type 51FRCT: Aluminum alloy bonnet, body, and filter bowl, 316 stainless steel internals, Inconel alloy range spring, nitrile diaphragm (fluorocarbon optional), 316 stainless steel valve assemblies, and finished with epoxy paint. All metallic parts for this unit conform to NACE material requirements #MR-01-75. These regulators are available standard (Type 51R) or as filter-regulators (Type 51FR, Type 51FRCT & Type 51FRWT) and are even available with an automatic drain, for automated flushing out of contaminants (Type 51 AFR). These versatile regulators provide excellent regulation for a wide range of applications, including pneumatic instruments, controllers, chucks, and actuators. They can be through-panel mounted
