BALL VALVES

 

 

** Trunnion Ball Valve - Side Entry Bolted Body Sizes: ½"-60"

API classes 150 to 4500  pressure 2,000 psi to 10,000 psi also available

Type: 
Double Block and Bleed, Side entry, Split body design, Fire Safe, Full / Reduced Port, Antistatic device, Blowout proof stem, Lever operated, Gear Operated or Actuated.

Ends:
Flanged RF / RTJ ; Butt Weld Ends; Hub Ends
Materials of Construction:
Carbon Steel, Stainless Steel, Low Temp Carbon Steel, Duplex, Super Duplex, Super Austenitic Stainless Steel, and exotics like Inconel, Monel, Hastelloy etc.
Features:

  • Double Body Sealing ensures positive body joint sealing against pipeline stresses. Also beneficial in fugitive emission and vacuum applications.

  • Multiple Sealing Stem with O-rings enhances stem sealing capabilities to atmosphere assisting in fugitive emission and vacuum applications.

  • ISO-5211 Top flange is available on all valves, enabling on-site actuator mounting and use of standard mounting hardware.

  • Blow out proof stem using a machined shoulder which ensures stem cannot “blow out” under pressure.

  • Antistatic design using spring loaded balls in stem which ensures constant contact between ball & stem and stem & body dissipating any static charge generated.

  • Fire Safe design valves are Virgo’s standard offering conforming to API 607 and API 6FA. Valves are tested and Fire Safe certified by Lloyds Register.

  • Double Block and Bleed Design.

  • Self Relieving seats for body cavity pressure relief.

  • Emergency Seat and Stem sealant injection systems available.

  • Specially designed seats and seals in a variety of materials to suit specific applications.

  • Valves with Double Piston Effect Seats, Valves with extended stems, valves for underground applications
