UHMW diaphragm and sealing head. Includes fluid inlet fittings #7021499 and #7007038. Piston Spring Diaphragm Mounting Hole 1/8 NPT Fluid Body Shaft Locking Screw Piston Stop Body Cap Fluid Outlet 1/4 NPT Shaft Sealing Head Tip Adapter Guide Pins Piston Air Cylinder Cap Air Cylinder Body Fluid Inlet 1/8 NPT Actuating Air Input 1/8 NPT The 725D Series valve systems consistently dispense a wide range of medium to thick fluids, including greases and silicones. The 725DA-SS provides stroke adjustment for both fluid flow and snuff-back control. The 725D-SS version is non-adjustable and provides fixed stroke travel. “Watching EFD valves is boring. And that's great. They just keep working and working.” – Peavey Electronics For use with • Braze Pastes • Epoxies • Greases • Paste Fluxes • RTV / Sealants • Solder Resists See ValveMate Controllers for system setup.
