Nickel-Plated Brass Pilot-Operated Check Valve/
Blocking Valve
NPTF/Inch Series VBU, VBO
Swivel Design : 5/32” OD Push-In Fitting Pilot
Thread Type : 1/8”, 1/4”, 3/8” NPTF with Pro-Fit Reusable PTFE/Teflon Thread Seal
These unidirectional and bidirectional
blocking valves have been realised in
order to enable mounting directly on
cylinders.
The inner design of the blocking valves
Series VBO and VBU allows a very high
flow rate and reliable operation.
These valves can be mounted directly
also on distribution and fluid control
blocks.
