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.
Featuring patent pending improved valve seat sealing that eliminates the risk of media leakage often associated with conventional high pressure regulators, the new Rotork Fairchild range incorporates innovative diaphragm designs that deliver superior accuracy and higher performance pressure regulation, especially with fluctuating supply pressures.
Rotork Fairchild high pressure pneumatic regulators come in 316 stainless steel construction, and a choice of two designs for varying pressures: the HPD diaphragm design suits pressures up to 413 Bar (6000 psi) while the HPP piston design supports even higher supply pressures.
The HPD design pneumatic regulators feature 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 model will also handle temperatures up to 260°C and increase the supply pressure capability to 689 Bar (10,000 psi).
Common features of the HPD and HPP pneumatic regulators:
- Available with 6mm (¼”) ports in 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
- Can be mounted at the ports, the bottom surface or in panel mounted configurations
