KPR1/4" Pressure Regulator
Classification: Pressure Regulators
Max. Working Pressure: Import160bar/Export0.2～35bar
Working Temperature:-80℃～+200℃
Body Material: 316L Stainless steel
Product details：
KPR Stainless Steel Diaphragm Pressure Regulator(-80℃~+200℃)
Uses: KPR series precision pressure regulators are intended for pressure reduction or accurate pressure setting and frequently used for gas cylinder or branch pressure control. They are applicable to filtered air, N2, CO2, water and other gases or low-viscosity liquids compatible with valve material (for use with O2, please contact us).
Features
● Corrosion-resistant 316L stainless steel diaphragm, highly sensitive
● 316L stainless steel body, no rubber, high temperature rating, corrosion-resistant
● 25 μm filter screen in the inlet
● Adjustable safety relief valve for protecting pressure gauge and other elements
Technical Data
● Max. inlet pressure: 160bar
● Outlet pressure control range: 0.2~35 bar
● Working temperature: see “Table of Seat Sealing Materials”
● Flow coefficient Cv: 0.2
● Openings: 1/4NPT female inlet/outlet, 1/4 NPT female pressure gauge connection, 1/4NPT female relief valve connection
Note: If it may be closed or have a low flow downstream, the outlet tube needs an exhaust branch in order for reducing outlet pressure.
