Pressure regulator pilot-operated »SYNTESI«, size 2, G 1/2 - Riegler 146087

Pressure regulator pilot-operated »SYNTESI«, size 2, G 1/2, p1 = max. 13 bar, T = -10 … 50 °C, without pressure gauge The pilot operated regulator can adjust pressure remotely via a pneumatic command. The two rolling diaphragms offer several advantages: - Increased stroke, which allows greater opening of the valve and hence increased flow rate. - Reduced dynamic and pickup friction, which results in increased response speed and high sensitivity. - High precision in maintaining the set pressure, both with variable flow rates and different inlet pressures. The design features the same construction characteristics as those used for a standard regulator, so the advantages are the same, namely: - Compensation of the regulated pressure varies with the upstream pressure. - Presence of a relieving valve and downstream pressure quick relieving.

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
