Instrumentation valve TESCOM™M25

ballmanualisolation

Two-valve single outlet gauge valves that combine isolating, calibrating and venting facilities in a single compact unit 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.
