backseat facing

English to Spanish Tech/Engineering Mechanics / Mech Engineering valvulas
Hi there,

This is a functioning and maintenance manual for gate valves.

Here is one sentence:

During operation, the shut-off valves should be completely opened up to the position of the backseat facing.

Another:

The xxx bolted bonnet valves come with integral backseat facing, therefore, when in the all-open and backseat facing position they do not cause any leaks towards the outside during any type of operation

cheers!

Carlos

Back seating the valve and attempting to repack under pressure is
hazardous and is not recommended. Rather than attempting to repack
under pressure, it is preferable to use the backseat to control the stem
leakage until a shutdown provides safe repacking conditions.
