Introduction
The 725HF Series is simple to use and will operate many
millions of cycles without maintenance.
The unique design of the 725HF Series valve provides a
clean fluid cutoff with pullback for precise fluid application
at high cycle rates.
Each 725HF-SS and 725HF-A valve is shipped with a
dispensing tip adapter, fluid inlet fitting and 5-foot actuating
air hose installed. For high-flow applications, the dispensing
tip adapter can be removed for installation of 1/4 NPT
metal or plastic nozzles.
The 725HF-A is identical to the 725HF-SS, except the
fluid body and cap are acetal copolymer, and the shaft
and the sealing-head screw are Teflon
steel.
