Throttle Valve
Introduction
The types BLE and BLX throttle valves
function as a by-pass on transmission
stations reducing pressure.
The type BLX version is equipped with a
type OS2 release relay to cut off the gas
flow in case of outlet over pressure.
The types BLE and BLX are in conformity
with the Pressure Equipment Directive
PED 97/23/CE and are classified under
Category IV.
