Features

• Packing below threads (O-ring bonnet) prevents lubricant washout, thread corrosion, process contamination and eliminates galling.
• Easily adjustable packing decreases replacement downtime and increases valve life.
• Safety back seating prevents stem blowout or removal during operation and provides a metal-to-metal secondary stem seal while in the fully open position.
• ENC plated 316 SS prevents galling or freezing of stem threads.
• Rolled stem, bonnet and male NPT threads provide additional strength.
• Mirror stem finish in the packing area enables smooth operation and extends packing life.
• One-piece handle design prevents loss due to vibration or during maintenance.
• Soft or metal seat for bubble-tight shutoff is field-replaceable for easy maintenance.
• Extended valve life: damaged soft seat can be removed, leaving a metal seated valve.
