The 754V-SS wetted components are constructed of 316L stainless steel and Teflon® with a smooth aseptic fluid path. [. . . ] Fill reservoir by pouring fluid directly into tank liner or manufacturer's bottle placed inside reservoir. Set reservoir pressure to low for thin fluids and higher for thick fluids. Set the stroke control starting with no more than 1/2 turn open from closed position. Place a cup under the dispensing tip and actuate the valve until fluid lines, valve and dispensing tip are free of air.

Refer to valve controller operating manual. How the Valve Operates Input air pressure at 70 psi (4. 8 bar) forces the internal piston to move. The piston rod pulls open the diaphragm seal, permitting fluid flow. When the input air pressure is relieved, the spring retracts the piston and the diaphragm closes. The amount of fluid dispensed will depend on the time the valve is open, the viscosity of the fluid, the air pressure in the fluid reservoir, the dispensing tip size and the diaphragm stroke. Flow rate is a function of reservoir pressure, tip size and fluid viscosity. 754V-SS Fluid Flow closed open The primary control of deposit size is the valve open time. ValveMate Concept The ValveMate 7000 provides easy adjustment of valve output for maximum end-user convenience and efficiency. Valve open time is the primary control of deposit. The 7000 puts push-button adjustment of valve open time where it needs to be ­ near the valve.
