HP301

Line pressure regulator

dual stage max. 300 bar inlet pressure

HP 301 is a dual stage line pressure regulator and recommended for high purity gas applications.

Due to the dual stage construction the wor- king pressure of HP 301 is absolutely stable even if inlet pressure drops down.

To identify the correct order code for your HP301

Start with "HP301-", then add the appropriate number options from columns A, B, C & D in the table below followed by the gas to be used.

HP301-1-3-1-3-Argon specifies a HP301 model in stainless steel with 1-6 bar outlet pressure ranges, without guages & 3mm inlet and outlets, for use with Argon gas.

A	B	C	D
Material	Outlet pressure ranges	Gauges	Inlet and outlet option
1 = stainless steel electropolished	1 = 0.1 - 1 bar	1 = without gauge	0 = NPT 1/4“ f
2 = brass, nickel and matt chrome plated	2 = 0.1 - 3 bar	2 = outlet gauge (working pressure)	3 = compression fitting 3 mm
	3 = 1 - 6 bar	3 = in- and outlet gauges	6 = compression fitting 6 mm
	4 = 1 - 12 bar		8 = compression fitting 8 mm
			10 = compression fitting 10 mm
			12 = compression fitting 12 mm
