CAUTION
The stackable control head (P/N 82-486500-010) cannot be used with 3 in
valve cylinders (P/Ns 90-100600-100, 90-100601-100, 90-100900-001 and
90-100901-001). The stackable control head does not have sufficient force to
activate the 3 in valve (P/N 90-17000-000) and may result in a system failure.
The electric/manual control heads (P/Ns WK-890181-000, 81-890149-000,
and WK-890165-000) may be used with the 3 in valve.
