KREBS Ball-Check Valves, Isolate the duty and standby pumps in your mineral processing circuit with our two-way, floating ball-check KREBS Tech-Taylor Valve (TT). Requiring no air or electricity to operate, the Tech-Taylor Ball-check valve is the most cost-effective and efficient answer for pump isolation when you have two pumps in parallel.The Tech-Taylor Valve performs these functions automatically, operating in any position, without any external energy source. It prevents the need for multiple knife gate valves and expensive rubber-lined piping components. The body of the TT Valve replaces the Y fitting formerly required for standby pumps and is designed for maximum abrasion resistance and minimal pressure drop making it a trouble-free addition to your piping system. Designed for installation in equipment where there are two pumps operating in parallel, it allows either of the pumps to work individually, as well as simultaneously during the changeover.

• TT Valves are available in sizes from 80 mm (3-in) to 250 mm (10-in) in cast bodies and 80 mm (3-in) to 750 mm (30-in) in fabricated bodies, with flanged or Victaulic connections, and pressure ratings of 150, 300, 450 and 600 psi. Lining materials can include pure gum rubber, chlorobutyl, neoprene and EPDM
• The T2 series is designed for one operating pump and one standby pump. All connected pumps may be operated simultaneously during changeovers
