A High-purity regulator designed for analytical applications. Use with non-corrosive gases.

Applications

• Supply of carrier gas / detector support gas for a variety of gas chromatography applications
• Supply of calibration standards to on-line process analyzers, emission monitoring systems, etc.

Design Features

• High-purity nickel plated brass barstock body
• High-purity 316 stainless steel diaphragm
• Metal to metal seals minimize diffusion of contaminants
• 2-1/2” inlet and delivery pressure gauges
• Equipped with outlet diaphragm valve
• Bonnet ported and threaded to pipe gases away from work area
• 1/4” compression tube outlet connection
• 10 micron metal filter protects seat from contamination
• Panel mountable, front bonnet thread and back (10-32UNF)
• Bonnet vent hole size: 1/8” NPTF

*Note: where CGA is replaced by the actual CGA number. Some CGA limitations may apply. (NI) for 1/4" FNPT inlet

	Mounting Options
	Mounting Bracket for Single Stage & Line Regulators Two 10-32 screws are needed to mount the back of the regulator to this bracket.
	Mounting Bracket for Regulators PMK-2N Mounting Nuts are also needed (see below). The regulator knob will have to be removed in order to mount on this bracket.
	PMK-2N Mounting Nuts These nuts can be used either with the above bracket or for mounting in a panel.
	53 Series Protocol Station This brass manifold is designed to provide a safe, reliable way of wall-mounting a cylinder regulator. Manifolds are provided a durable stainless steel bracket, stainless steel flex hose (3 ft std.), and a CGA connection with integral check valve.
