- A large conical stem hole going all the way through the wedge ensures circulation and prevents stagnant water
- Triple safety stem seal with an NBR wiper ring outermost to protect against contamination from outside, in the middle two O-rings around the replaceable radial bearing, and innermost an O-ring is the main seal to the system pressure
- Wedge shoes in PA and guide rails on the body make the wedge slide easily up and down regardless of differential pressure
- Stem in duplex 1-4462 stainless steel with wedge stop and rolled threads for high strength
- Bonnet gasket in EPDM with a circular cross-section, fixed in a recess to avoid blow-out
