Hydraulic Circulating Valve

Hydraulic Circulating Valve Hydraulic Circulating Valve is a FUL-FLO circulating tool. It can be connected above or below the tester. When connected below the tester, hydraulic circulating valve is used as a bypass of packer. This can reduce the tool from drilling and suction effect of descenting down hole. When connected above the tester, hydraulic circulating valve is used as a circulating valve. The valve plot column formation fluid in pipe string after testing, Hydraulic circulating valve consists of delay part and by-pass part. Delay part consists of vat, measuring set and other spare parts. By-pass part consists of circulating outer barrel and circulating set and other spare parts.
