Rotork Fairchild launches innovative high performance polymer pressure regulator

20/06/2013

 

Rotork Fairchild has introduced a new polymer pressure regulator with innovative features for high precision pressure control duties.

The Model 55 pressure regulator features a non-rising stem within a small footprint design, delivering high precision control in a lightweight and compact package.

Manufactured entirely from polymer and stainless steel, the Model 55 offers compatibility with medical and scientific gases such as nitrogen, helium and oxygen. Applications include precision pressure decay and leak testing, medical ventilators, respiratory diagnostic systems, balloon pumps and sterilisation equipment.

A patent-pending venturi design compensates for downstream pressure droop under flow and provides highly accurate pressure output control under all conditions. The separate control chamber isolates the control diaphragm from the main flow to eliminate hunting and buzzing.

With supply capacity up to 150 psi (10 Bar) and flow capacity up to 10 SCFM (283 litres/minute) the Model 55 controls output pressures up to 100 psi (7 Bar) to within +/- 0.2 psi (14 mBar) or better, even with fluctuating or rapidly decreasing supply pressure. This high pressure capability, combined with pinpoint accuracy at low control pressures of 7.5 psi (0.5 Bar) or less, sets the Model 55 apart from conventional regulators for demanding applications.

All–new low pressure regulator on two week delivery from Rotork Instruments

17/04/2013

 

Rotork Fairchild, a member of the Rotork Instruments Division, announces the introduction of the all-new Model 11 low pressure regulator. Available on a 1-to-2 week delivery, the Model 11 provides a reliable and highly accurate solution for very low pressure control applications.

Designed to handle the most challenging duties, typical applications include leak detection systems, tank blanketing, air and gas sampling systems, analytical equipment, soil sampling and test stands.

Available in a range of five sizes, the Model 11 features superior repeatability and sensitivity of 0.05 inches of water column (1.25mm WC) for ease of setting. Flow is critical for most applications and to meet this demand the Model 11 delivers a flow capacity of 24 SCFM (28 litres/second).

The Model 11 design incorporates a diaphragm diameter engineered for optimum performance within a compact package, offering an ideal solution when the overall envelope size must be minimised. Tamper-proof, screw or standard knob actuation alternatives provide versatility and ease of use. Nitrile or optional fluorocarbon elastomers enable the Model11 to work in any environment.
