CODING OF UNIDIRECTIONAL AND BIDIRECTIONAL VALVES
UNIDIRECTIONAL AND BIDIRECTIONAL BLOCKING VALVES
pilot pressure
flow rate
The diagram below shows the relation between working pressure and
pilot pressure required in order to operate the valve.
The opening pressure of the unidirectional valve is 0,3 bar (4.35 psi).
Flow Q (Nl/min.) [SCFM]
N.B.:
Q is determined with an inlet pressure of 6 bar (87 psi).
