Anderson Greenwood (AGCO) H1 Instrumentation Hand Valve – Large
The TESCOM™ AGI – Anderson Greenwood (AGCO) H1 large instrumentation hand valve has a large bore, 3/8″ (9.5mm) diameter orifice, and is suitable for instrument isolation duties providing repeated reliable bubble-tight shutoff. The H1 large valve features an optional metal-seated bonnet assembly which has a rotating stem, and non-rotating plug. The stem threads are rolled and lubricated to prevent galling, and reduce operating torque. This needle valve is available with a PTFE or graphite packing which is adjustable in service. All bonnets are assembled with a bonnet locking pin to prevent accidental removal while in service.
Features
- 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
- 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 for added 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 breakage, and gives a reliable seal point
