Technical specifications and operating parameters for the Atlas Copco 2901021701 oil stop valve kit C106. This service kit is installed in the oil circuit of oil-injected rotary screw compressors to control oil flow to the compressor element and prevent unwanted oil migration during unloaded or stopped conditions. The kit functions as a check valve assembly engineered to prevent reverse oil flow during compressor unloading and shutdown cycles. Designed as an OEM replacement for Atlas Copco C106 and similar fixed-speed rotary screw compressor models including GA series. Constructed to meet strict OEM standards for durability and high resistance to pressure variations in demanding industrial compressed air applications.
