Soft seat replaceable valve operates in dirty service with repetitive bubble-tight shutoff.
Packing below threads prevents lubricant washout, thread corrosion, process contamination and eliminates galling.
Easily adjustable PTFE packing decreases replacement downtime and increases valve life.
Dust cover protects stem from lubricant contamination.
Safety back seating prevents stem blowout or accidental removal and provides a metal-to-metal secondary stem seal while in the fully open position.
ENC plated 316 SS stem prevents galling or freezing of stem threads. CS valves use a 303 SS stem for 'hard-to-soft' contact, to prevent galling.
Rolled stem and bonnet threads provide additional strength.
Mirror stem finish in the packing area provides smooth operation and extends packing life.
Straight-through flow path means high flow capacity, bi-directional flow and rodding capabilities.
Metal-to-metal body-to-bonnet seal in constant compression prevents bonnet thread corrosion, eliminates possible tensile
