ABYC H33.9.2 states that fuel system valves must have an independent means of support. That’s why regular in-line valves are not appropriate for fuel systems applications. These Groco full-flow valves include cast mounting feet that accept #10 fasteners to secure the valve to a bracket or bulkhead. A patented selectable handle rotation allows uses to clock handle swing to match application space restrictions. Stainless steel handles and hardware with PTFE seals and seats are ideal for fuel or water applications and stand up to marine for a long service life.
