Rotork Fairchild: Compact Leak-Free High Pressure Regulators
Sept. 13, 2012
The new range features improved valve seat sealing that eliminates the risk of media leakage often associated with conventional high pressure regulators.
In addition, new 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 diaphragm 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 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 diaphragm and piston designs are available with 6 mm (1/4-in.) ports in either two- or four-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. Regulators can be mounted at the ports, the bottom surface or in panel mounted configurations.
