7021514 754V-SS Valve
Wetted components are made of 316L stainless
steel and PTFE, to conform to biopharmaceutical
regulations. Internal threads have been removed to
provide a smooth, easily cleaned fluid flow path, free
of entrapped areas. Fluid body is electro-polished to
increase corrosion resistance.
754V valve includes 1.5 m (5 ft) input air hose
with male quick-connect, barbed fluid inlet fitting,
polypropylene tip adapter, and dispensing tip kit.
754V Series
Aseptic Valve
The 754V aseptic valve features a smooth uid ow path that is free of any entrapment
areas. FDA-compliant wetted parts are made of 316L stainless steel and PTFE, making
the valve suitable for CIP (Clean-In-Place) and SIP (Sterilize-In-Place) processes.

The 725D Series valve systems consistently dispense a wide range of medium to thick
uids, including greases and silicones.
The 725DA-SS provides stroke adjustment for both uid ow and snuff-back control.
The 725D-SS version is non-adjustable and provides xed stroke travel.
