VR6 Series High Pressure Regulator Valves
VR6 Series Pressure Rating up to 413bar (6,000 psig)
Features
Technical Data
• The High Pressure Regulator valve is featured by controlling the pressure toward
downstream from zero to 1,000 psig (68.9 barg) precisely and keeping the downstream
pressure constantly after adjusting, though the upstream pressure may be fluctuated
unexpectedly.
• The diaphragm made of thin plate of stainless steel is positioned between the body and
housing to make sure of stable sealing characteristics and keep the control volume.
