The high-velocity relief valve ( pressure/vacuum valve for cargo oil tank ) generally uses by the relief system of the oil tanker and chemical tanker.
The opening pressure of the vacuum valves are -3.5kPa; The opening pressure of the pressure valves on the oil tank is 14kPa, on the chemical tank is 18-20kPa. The opening pressure of the pressure may be different, but the differences of opening pressure and flow range is inapparent if the pressure valves have the same diameter.
