East Providence, RI, The new 754V-SS is a precision dispense valve with an aseptic design that reduces the risk of contamination in sterile fluid filling processes. Typical uses include filling contact lens packages with saline, dispensing monomers into lens molds, filling vials with drugs, and small-volume food and beverage applications.

The 754V-SS uses a unique, low-maintenance diaphragm design to provide fast, precise dispensing of most low- to medium-viscosity fluids. It can be cycled up to 500 times per minute, with shot size ranging from 0.5 microliters to a continuous flow rate of 60 microliters per second. A fast, clean cutoff after each shot prevents drips and waste.

To ensure sterility and simplify cleaning, the valve’s fluid path is smooth and free of areas where contaminants or bacteria could collect. Wetted parts are made of FDA-compliant 316L stainless steel and PTFE (PolyTetraFluoroEthylene) suitable for Clean in Place or Sterilize in Place processes. Instead of seals or O-rings that could wear out and leak, the 754V-SS uses an inert PTFE (PolyTetraFluoroEthylene) diaphragm, conservatively rated at 108 cycles, to isolate the fluid from the valve’s internal parts.

The amount of fluid dispensed is determined by a combination of fluid pressure, flow rate and valve open time, with open time regulated with a microprocessor-based ValveMate™ controller. Mounted near the valve, the controller simplifies system setup and allows open time to be adjusted in increments as small as 0.001 seconds, for exceptionally precise and consistent shots.

Compact, lightweight, and simple to install, the 754V-SS valve is ideal for automated assembly machines, XYZ tables, and retrofits on current production lines.
