General Description
2-Way Manual Poppet Valve. The DL081 Series Valves
are suited for emergency lowering applications and on-
off flow applications.
Operation
The DL081 Series Valves are mechanically operated
check valves. Hydraulic force on the poppet is bal-
anced by having equal area between the poppet seat
and the valve stem, allowing the poppet to be manually
pulled off the seat. When released, the bias spring will
return the valve poppet to its closed position. Back
pressure of more than 5.5 Bar (80 PSI) will prevent the
bias spring from closing the poppet and must be
avoided.
