Rotork Fairchild, a member of the Rotork group of flow control companies, 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 413barand 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 1.66bar. It is available with the standard polymer valve seat for media temperatures up to 80°C and supply pressures up to 241bar. Optional higher performance valve seats are fitted for temperatures up to 260°C and a maximum supply pressure of 413bar. The all-stainless steel HPP piston design models will also handle temperatures up to 260°C and increase the supply pressure capability to 689bar.
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.
