Danfoss Hansen FD72 Series coupling incorporates special
valving allowing connection to a FD76 Series male half
under pressure. The maximum operating pressure is 3,000
psi. Contains an over travel, selfsealing poppet valve
construction for connecting to a pressurized male tip.
Applications require that the tractor control valve be
actuated to open the flow path and to equalize the
pressure.
