Features

• Compact design minimizes space requirements; low weight improves connection strength and reduces gauge whip.
• Minimal instrument installation components reduce costs and decrease possible leak points.
• Easy instrument check calibration using ¼" FNPT vent/test port.
• Ball end stem eliminates seat galling, provides bubble-tight shutoff and long life. Hardened, non-rotating ball ensures perfect alignment closure.
• Packing below threads 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 accidental removal and provides a metal-to-metal secondary stem seal while in the fully open position.
• Dust cover prevents lubricant washout and protects bonnet assembly from contaminants.
• 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.
• Metal-to-metal body-to-bonnet seal in constant compression prevents bonnet thread corrosion, eliminates possible tensile breakage and gives a reliable seal point.
