The EPO-2 valve features
our world renowned UNI-Valve (RPV mechanism), as well as a second
check valve. This ingenious system enables the user to fill the cylinder
with the handwheel in the closed position. This system is not only a cost
saving for the company, but is user friendly in as far
as it can greatly reduce the risk of Carpal Tunnel Syndrome
which can afflict the filling operations personnel.
