A Double Block & Bleed Ball-Needle-Ball Valve Manifold with pressures rated up to 10,000 psi / 690 bar. 

Manufactured from forged barstock, the two inline balls provide unrestricted flow with a roddable facility and are the primary and secondary isolating valves with a needle type valve for the vent facility. 

The ball valve is designed to give bubble tight shut off through a 90° operation across the full operating temperature range of the valve.  
Features
  • Anti-blow out stem internally loaded
  • Bi-directional
  • Precision machined stainless steel balls
  • Lever type handles as standard
  • Tamperproof lockable handle is available on both isolates and vents (option available)
  • Compact design to save space and weight
  • Full material traceability and individual serial number stamped on the valve
  • In compliance with NACE MR-0l-75 / ISO l5l56 as standard
  • RTFE stem seal and O-ring body seals
  • Stem seal design prevents galling and contamination
  • Panel mount as standard
  • Thread milled connections for improved sealing
  • Bubble tight shut-off
  • Low operating torque
  • Pressure energized stem sealing
