Heavy-duty pressure regulators

	Heavy-duty pressure regulators
	Diaphragm pressure regulators, independent of inlet pressure, with internal pilot control and self-relieving design for very high flow rates. Separate indication of input and working pressure on two pressure gauges. The pressure setting can be locked by pushing the knob down. We recommend always using these controllers in conjunction with our 650 G/M and 650 H/M filters.
	Input pressure:		Max. 25 bar
	Medium temperature:		Max. 60 °C
	Ambient temperature:		Max. 60 °C
	Body:		Aluminium, painted silver
	Sealant:		NBR
	Flow rate measurement:		At P₁ = 8 bar, P₂ = 6 bar and pressure drop Δ_p = 1 bar
	More information:		Data sheet 2-30
