Inline pressure regulator for drinking water G 1/4, pre-set 6 bar - Riegler 150643

Inline pressure regulator for drinking water, without venting, G 1/4, AF 17, Working pressure (pre-set) 6 bar, PN max. 10 bar This potable water regulator reduces the inlet pressure to a fixed set output pressure, that is factory set and cannot be changed. This makes the regulator secure from manipulation. Due to the constant output pressure pressure fluctuations in the system are prevented and the down-stream equipment and components of the potable water line are protected. The pressure regulator complies with the FDA, EU and DIN 50930-6 potable water directives and can be used in the potable water area, in the food industry and in medical technology.

About Pressure regulators

Pressure regulators hold the outlet pressure steady even when inlet pressure varies or consumption changes. The range covers control ranges starting between 0 and 5 bar and ending between 1 and 200 bar, with inlet pressures up to 60 bar. Ports run from G 1/8 to G 2.

What matters when choosing

• Control range: lower limits sit between 0 and 5 bar, upper limits between 1 and 200 bar. Keep the working pressure inside the range rather than at its edge.
• Flow rate from 1000 to 50000 l/min: the regulator has to cover peak demand, otherwise secondary pressure drops away on every load peak.
• Medium: besides compressed air and neutral gases there are versions for drinking water, nitrogen and argon, plus variants for ultra-fine filtered oil-free air down to 0.01 µm.
• Body material: aluminium, aluminium die-cast, brass, zinc die-cast, technopolymer, PA66 GF60, stainless steel 1.4404 (AISI 316L) and gunmetal in the Rg5, CC499K and 2.1096.01 grades.
• Series: alongside the mechanical FUTURA, SYNTESI, multifix, variobloc, inline and Standard lines, the electronically controlled REGTRONIC 300 and 400 series handle setpoint-driven applications.

Typical applications

• Holding a steady working pressure at machines and air tools
• Reducing mains pressure to the level required by individual sub-circuits
• Setpoint-driven pressure control on test rigs using the electronic versions
• Pressure reduction in drinking water lines
• Feeding test and measuring rigs with nitrogen or argon

Sealing materials include NBR, FKM, FPM, EPDM, SBR, PU, HNBR and TPU depending on the series. 102 items are rated to protection class IP 65.
