  • All bonnets are assembled with a locking pin to prevent accidental removal while in service.
  • The stem threads are rolled and lubricated to prevent galling and reduce operating torque.
  • 100% factory test. Every valve is tested with nitrogen for leak-tight performance at its maximum working pressure.
  • Panel mounting options available.
  • For soft seat 6,000 psi pressure rating (@ 100°F maximum)
  • For hard seat 10,000 psi pressure rating (@ 100°F maximum)
  • Orifice Size : 0.138" (3.5mm) to 0.250" (6.4mm)

Testing

Standard Test Each valve is factory tested with nitrogen at 1000 psig (69 bar) for leakage at the seat and packing, the maximum allowable leak rate of 0.1 sccm.
Optional Hydrostatic test This test is performed with de ionised water at 1.5 time the working pressure. Other tests like vibration, temperatures, helium etc are available upon requests.

Packaging

All exposed threads of the product s are Protected with plastic caps to prevent damage and each assembly is packed in sealed and clear polyethylene bag for cleanliness and carefully packed in cardboard boxes to prevent transit damage. Each and every package is labelled for proper and easy identification.
