The Frank’s International BRUTE® Circulating Valves, including the BRUTE® Force and BRUTE® Unloader, are the industry’s first to be tested to ISO 14310, API 11D1, and API 19AC V3 Annex A/D standards. When paired with our BRUTE® Retrievable Service Packer, the BRUTE® Force or BRUTE® Unloader Circulating Valves form the BRUTE® Test System to provide safe and efficient negative and positive tests by serving as both a circulating and fluid bypass valve.
