Model 725DA valve provides dispensing of medium- to high-viscosity fluids such as epoxies, lubricants, RTVs, solder masks, and brazing pastes. A piston stroke adjustment provides adjustable fluid-flow and snuff-back control. The valves can be used for tens of millions of cycles with minimal maintenance, and have no seals to wear out and leak. Instead an inert polyethylene diaphragm isolates the valve's actuator from its wetted components.
