s.55 KFE cap & strap

Info request

full port 1/4″
hot forged brass ball valve

Many HVAC applications require a blowdown valve to drain water from the strainer.

RuB ‘s new s.55 cap & strap valve is designed with a full port for maximum flow.

Because of the O-ring stem seal design, no maintenance is ever required.
3/4″ thread gives the possibility to easily fit a hose holder available as option, for the connection of a waste water collection pipe.
