High-velocity relief valve (pressure vacuum valve) is the controlled venting system the safest production for oil tanker and chemical tanker.
He series of CF-type P/V valve is a new generation production without vibration and anti-collision. It is installed on the vent pipe of oil tanker and chemicals tanker. It is the only entry and exit for liquid cargo tank. 1. When loading the liquid cargo or ballasting, the pressure valve in the high velocity relief will open, then jet out combustible liquid cargo vapour/air-mixture in liquid cargo tank with the rate of more than 30m/s, and dilute in the air so that it will never drop on the deck. 2. When unloading the liquid cargo, the vacuum valve in the high velocity relief valve will open, then supply air to cabin safely so as to avoid the cabin is over-vacuumed. 3. When the tank navigate on sea, the high velocity valve can automatically adjust the pressure oscillation in the cabin which caused by temperature changes

The company specially manufactures the marine safety equipments and fire protection equipments which was built in 90s.
Recently, the high velocity relief valve (pressure/vacuum valve) which---was researched and manufactured by itself, has got the technology innovation fund for medium or small enterprise, and filled the domestic gap. It also was built by our company firstly in China.
Marine series high-velocity relief valve and laboratory for the high velocity relief valve was ratified by the China Classification Society and some foreign classification societies.
The series high velocity relief valve, which was manufactured by our company that has became the essentials in oil tank and chemical tanker both at home and abroad.
Our tenet is to contribute in the marine safety industry, create the A-class products and serve for all the customers. We also insist on Quality comes first, safeguard our credit.
