PHR

Precision pressure regulator

single stage for mbar applications

The excellent gas control characteristics of PHR - even in the mbar area starting with 10 mbar is based on the wide and flexible diaphragm construction.

As an option the PHR regulator can be deli- vered with in- and outlet pressure indicators or with a wall mounting bracket.

To identify the correct order code for your PHR

Start with "PHR-", then add the appropriate number options from columns A, B, C & D in the table below followed by the gas to be used.

PHR-1-2-1-03-03-Argon specifies a PHR model in brass with 50mbar outlet pressure ranges, without guages, 3mm inlet & 3mm outlet for use with Argon gas.

A	B		C	D
Material	Outlet pressure ranges		Gauge	Options for in- and outlet
1 = brass	1 = 30 mbar	7 = 500 mbar	1 = without	00 = G 1/4“ f
2 = stainless steel electropolished	2 = 50 mbar	8 = 700 mbar	2 = with working pressure indicator	03 = compression fitting 3 mm
	3 = 70 mbar	9 = 1000 mbar	3 = in- and outlet pressure gauges	06 = compression fitting 6 mm
	4 = 100 mbar	10 = 1500 mbar		08 = compression fitting 8 mm
	5 = 200 mbar	11 = 2000 mbar		10 = compression fitting 10 mm
	6 = 300 mbar			12 = compression fitting 12 mm
