High Velocity P/V Valve

High Velocity P/V Valve

• Model : NEW ISO-HV Series

Applications

• Crude Oil Tankers
  
• Product Tankers
  
• Chemical /Oil Tankers
  
• Floating Production and Storage Offloading (FPSO)
  
• Shuttle Tankers
  
• Tank Farms
  

Benefits & Credentials

Besides preventing hull and tank stress due to over and under pressure during loading and unloading of liquid cargo, the ISO series is also designed to prevent the flame passage into cargo tanks. This complies to IMO MSC/Circ. 677/1009, ISO 15364 and vapor control system of USCG (46 CFR.39-20.11 & 162.017).

Principle

U-ISO-HV series of high velocity Tank Venting valves are non-hammering, non-oscillating, non-accumulating of condensate and non-corrosive for marine cargo tanks with simple operation and technically advanced designs.

Features

• Relieves excessive pressure during loading, discharging, ballasting and thermal variations.
  
• Prevents sea water from entering water ballast tanks.
  
• Gas-freeing cover.
  
• High velocity pressure.
