TANKTECH -High Velocity Pressure/Vacuum Valve

U-ISO-H/V/G series high velocity pressure/vacuum valve is designed to prevent the flame passage into cargo tanks and to relieve excessive over pressure or under vacuum of cargo tanks during cargo loading, discharging, ballasting and thermal variation.
U-ISO-H/V/G series of high velocity pressure/vacuum valve, which provide Non-hammering, Non-accumulation condensate vapor and Non-corrosion for marine cargo tanks, are very simple and advanced models.
U-ISO-H/V/G series is designed to prevent the flame passage into cargo tank in compliance with IMO MSC/Circ. 677/1009, ISO 15364 and vapor control system of USCG  ( 46 CFR.39-20.11 & 162.017 )
