The high-velocity relief valve (pressure/vacuum valve for cargo oil tank) generally uses High-velocity relief valve (pressure vacuum valve) is the controlled venting system which is necessary for oil tanker and chemical tanker. The series of DF-type P/V valve is a new generation production without vibration and anti-collision...The pressure/vacuum valve 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 experiment of pressure/vacuum valve for cargo ships is done in the lab that is approved by the state organs. It is ratified by China Classification Society and some other classification societies through the following tests according to the above standards: 1. Fire Resistant Test 2. Re-burning Test 3. Frozen Test 4. Corrosion Resistant Test 5. Flowing Test

Our Company, Taixing Lanjie Shipping Safety Equipment is located in the south of the taixing city. By the changjiang River near Nanjing-Nantong Expressway and Jiangyin Bridge.
The company specially manufactures the marine safety equipment and fire extinguisher which was built in 90s.
Recently, The high velocity relief Valve which was researched and manufactured by itself. And filled the domestic gap. It was also 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.
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.
