Pressure regulator »SYNTESI«, size 2, G 3/8, 0…2 bar - Riegler 139683

Pressure regulator »SYNTESI«, size 2, G 3/8, p1 = max. 13 bar, p2 = 0 … 2 bar, T = -10 … 50 °C, without pressure gauge Pressure regulator with rolling diaphragm, which has a number of advantages compared to systems with flat diaphragms: - Larger stroke allows for wider valve aperture and therefore greater flow rate. - Decreased dynamic and pick-up friction and therefore quicker response and enhanced sensitivity. - Greater accuracy in maintaining the pressure setting, both with variable flow rates and different supply pressures. Thanks to a special compensation system, the regulators keep the pressure settings virtually constant, even when the upstream pressure changes. The adjustment knob is the push-lock type with the additional possibility to secure with padlocks. There is one connection each on the front and back (G 1/8 for size 1 and G 1/4 for size 2), which can be used for pressure gauges or pressure switches or as an additional air outlet. Pressure gauge not included in delivery! ATEX version on request!

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
