Simplicity in design is what separates EVS valves from the rest. In severe services, the fewer parts, the fewer possible areas of failure. In addition, those parts must be built to withstand high temperatures, pressures and corrosive materials. For more information, contact EVS Valves.
We coincidently fix our centerlines. The large spring load continuously holds the ball in the integral seat preventing flotation. If centerlines are off set, floating results and side loads on the seat lead to seat damage and leakage. For more information, contact EVS
Our standard hard-faced coating technologies are HVOF and Spray and Fused. For more information, contact EVS.
Unique self energizing and pressure energizing gasket ensures against leakage during thermal transients
Generously spaced 4 bolt gland plate allows easy access to “live loaded” packing bolts.
Our integral seat design eliminates a potential leak-path.
Beefy one-piece blowout proof stem designed for safety, built to last
Contact proof stem adaptor design prevents the stem from being accidently “knocked” into the ball slot, causing misalignment and leakage
Integral 90 degree stop plate design prevents over rotation and maintains critical alignment on manual operated valves
Rugged side mounted mounting bracket with ISO top pad for ease of automation.
With centerlines controlled inherently by the integral seat design, the critical stem packing area is protected from stem side-load issues. Our compact stuffing box and “live loaded” spring washers ensures packing is continuously “energized”.
