Rotork Fairchild pressure regulators selected for high accuracy

13/08/2013

 

Rotork Australia has supplied Fairchild Model 10 pressure regulators for research applications demanding highly accurate pressure control at the TRI Australasia facility near to Queensland’s Gold Coast.

TRI Australasia offers highly specialised services including a range of geo-synthetic testing and quality assurance programmes for a multitude of industries. The Fairchild Model 10 regulators have been installed on two processes where compressed air is used to check for the content of water retention within clay. Both processes demand highly accurate set point pressure supplies in order for the tests to maintain reliable results.

Fairchild Model 10 regulators are designed for applications where high performance and reliable set point accuracy are essential. Suitable for system pressures up to 34 bar (500 psi) and flow capacities up to 63 cubic metres/hour (40 SCFM), the Model 10 offers nine set point pressure ranges and is easily able to achieve the +/- 0.5% accuracy required for the TRI application.

Commenting on the Fairchild product, TRI Australasia’s Divisional Director Warren Hornsey said “We chose the Fairchild product due to the accuracy required and the strong name within the industry. It was also important for us to have the support that Rotork Australia can offer from their local Brisbane office.”

Low emission natural gas I/P transducers meet new environmental regulations

13/10/2015

 

Rotork Fairchild has refined its proven I/P (electric current to pressure) transducer technology to develop new models which exceed recently released government requirements for allowable natural gas emissions.

Rotork Fairchild TXI7850 explosion proof I/P transducers have long been approved for and utilised in natural gas operated instrumentation systems. The explosion proof evaluation of these units by underwriting agencies such as FM, ATEX and CSA, using standards covering a constant fuel gas presence, ensures safe and reliable operation in the field with compressed natural gas as the supply medium.

In the USA new government regulations require all pneumatic controllers at the wellhead to have a maximum consumption of 6 SCFH (Standard Cubic Feet per Hour). In Canada and other countries, carbon credits can provide economic incentives to utilise low emission products, so the challenge is to provide controllers which reduce or eliminate these fugitive emissions.

The new Rotork Fairchild TXI7850 series maximum consumption levels are 3.6 SCFH for the 3-15 psi output range unit and 5.5 SCFH for the 6-30 psi range unit. These rates are for natural gas as a media and applicable all the way to the highest pressure in each range (i.e. 15 psi and 30 psi respectively).

As part of Rotork Instruments, Fairchild provides a complete range of regulators, boosters, I/P transducers and other products. Rotork Instruments can also provide fully approved switchboxes, positioners, solenoid valves and other actuation and severe service components to complete the automated flow control package.

Fairchild I/P transducers deliver high accuracy at very low pressures

11/01/2016

 

Rotork Fairchild has launched a new range of compact low pressure I/P (electro-pneumatic) transducers for instrument, analytical and scientific control applications.

Precise pressure control, where output pressures must be accurately held at low pressures down to 70 mBar (1 psi), has traditionally been a difficult task for industrial instrumentation. The new Rotork Fairchild T7500 range of transducers is specifically designed for these low pressure control systems with set point accuracy of 0.1%, even at pressures of less than 100 mBar.

T7500 transducers accept supply pressures between 1.3 and 2 Bar (20 and 30 psi) with mA or VDC control signals to deliver critical high accuracy output ranges of 0-350 mBar (0-5 psi) and 0-1 Bar (0-15 psi). Flow configurations of 85 l/m or 200 l/m suit a wide range of application requirements. In addition, the T7500 can be ordered with DIN plug, NPT conduit or terminal block electrical connections styles to suit assembly requirements.

Applications in test and medical equipment, leak detection equipment and other precise scientific areas are ideal for the T7500 transducers. The rugged cast aluminium construction and vibration resistant internal componentry is designed to withstand the rigors of both portable and stationary mounted equipment often found in medical and test situations.

As part of Rotork Instruments, Fairchild provides a complete range of regulators, boosters, I/P transducers and other products. Rotork Instruments can also provide fully approved switchboxes, positioners, solenoid valves and other actuation and severe service components to complete the automated flow control package.

New range of compact leak-free high pressure regulators

07/08/2012

 

Rotork Fairchild has launched a new range of compact high pressure pneumatic regulators for instrument and industrial control applications.

The new Rotork Fairchild range features patent pending improved valve seat sealing that eliminates the risk of media leakage often associated with conventional high pressure regulators. In addition, innovative diaphragm designs deliver superior accuracy and higher performance pressure regulation, especially with fluctuating supply pressures.

Constructed with 316 stainless steel bodies, the units are available as the HPD diaphragm design for pressures up to 413 Bar (6000 psi) and as the HPP piston design for even higher supply pressures.

 

The HPD design features high strength Inconel diaphragms as standard and will accurately regulate output pressures down to 1.66 Bar (25 psi).  It is available with the standard polymer valve seat for media temperatures up to 80°C and supply pressures up to 241 Bar (3500 psi). Optional higher performance valve seats are fitted for temperatures up to 260°C and a maximum supply pressure of 413 Bar (6000 psi). The all-stainless steel HPP piston design models will also handle temperatures up to 260°C and increase the supply pressure capability to 689 Bar (10,000 psi).

 

Both the HPD and HPP designs are available with 6mm (¼”) ports in either 2 or 4 port configurations and in multiple output pressure ranges.  Standard knobs can be replaced with tamper proof caps for high temperature and/or non-adjustment applications. Rotork Fairchild regulators can be mounted at the ports, the bottom surface or in panel mounted configurations.
