Features

  • 316/316L stainless steel construction for superior corrosion resistance.
  • One-piece construction body provides strength.
  • 316 stainless steel pin prevents detachment of the bonnet from the body due to vibration.
  • Easy to assemble and replace packing.
  • Burr-free threads and internal surfaces reduce leaks, promoting accurate transmitter readings.
  • Compact design requires minimum space for operation and installation.
  • Dust caps are fitted to contain stem lubricant and prevent the ingress of contaminants.
  • Bonnet to body seals are metal to metal, No O-rings used.
  • Mounting holes provided for self-supporting application.
  • Combines isolating and venting in a single valve, eliminating the need for tubing and fittings.
  • Maximum standard pressure up to 6,000 psig @ 100°F (414 bar @ 38° C)
  • 100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance and reliability.
  • 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 times the working pressure. Other Tests like vibration, temperatures, helium etc are available upon requests.

Packaging

All exposed threads of the products 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.

Manifold Selection Information

The pressure-temperature ratings are taken for ANSI B16.34 for standard class valves and are based on class 2,500. Ratings for needle tip’s design are based on specific seat materials.
