Advantage
of NGT's Balanced Poppet
NGT's patented balanced design reduces the force
required to open the valve.
The
traditional ball and poppet
pilot check valve require large pilot pistons in order
to open the main seat. The pilot piston force must
overcome the force resulting from pressure trapped
behind the main seat. Large pilot pistons cause high
operating forces that decrease the life of the valve.
Longer
Life
A
typical ball type or poppet type check valve with the
same flow area as the balanced check will have 16 times
the force required to open the valve. Opening a valve
seat with 44 lbf for 10 million cycles would cause
significant wear, as opposed to 2.7 lbf for 10 million
cycles. The air cushions on both ends of the pistons also
help to reduce wear due to impact forces when the
balanced piston shifts.
Smaller
Size
The
absence of a large pilot piston translates into a small
design package. Compare our 3/8 nptf Midget Model with
the competitions for size and flow.
Easy
to Repair
To
repair, remove the endcap, insert a new cartridge and
replace the endcap. This can be accomplished in a few
seconds without removing the plumbing.
