• Tubular valve and sleeve construction
for high fluid flow with low pressure
drop
Danfoss Hansen FD49 Series meets NFPA standard
T3.20.15 and was developed in conjunction with HTMA
(Hydraulic Tool Manufacturer’s Association). Danfoss’
Twin-Guard™ sealing system prevents weepage at low
pressures and allows connection and disconnection
against pressure up to 500 psi.
