UNIDIRECTIONAL AND BIDIRECTIONAL BLOCKING VALVES
The diagram below shows the relation between working pressure and pilot
pressure required in order to operate the valve.
VBU - 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).
VBU
Pilot-operated check

VBO
Blocking valve
- (Pilots are 5/32” OD)
VBO-VBU 3/8
Diagram for valves VBU and VBO with G1/2 ports.
Q is the flow measured in Nl/min and determined with an inlet
pressure of 6 bar.
