The single biggest plus of a twin seal valve system is both upstream and downstream pressure is maintained against the valve. In addition the amount of undesired leakage is significantly reduced. In turn this means that when valves are closed that flow meters are more easily calibrated because they accurately measure the rate of flow of material in the system. Clearly, if inaccurate readings are being produced the potential for accidents and financial loss becomes much more likely. A well maintained general twin seal valve system shows that each valve is leak tight and therefore the system as a whole will be accurately calibrated.
Use in the fuel distribution industry
The twin seal valve was first developed in the fuel distribution industry. Any high school chemistry book will tell you crude oil is broken down in to its constituent parts by the action of heat in fractional distillation tower. Each component of crude, from the light gases to bitumen is collected at its boiling point and stored for later use. If you are operating a busy fuel distribution center for a number of clients who have different fuel requirements at different times, you are going to need to be able to access you kerosene or your diesel promptly and safely. In such an environment you need valves that will drop tight shut so that fuels do not get mixed up and effectively contaminated and cost you huge sums of money, not to mention the potential for accidents! Twin seal valves are proven to easily facilitate the separation of different constituents of crude oil within the piping network.
Use in loading and uploading
Twin seal valves have general utility across a wide range of industries. In any situation where a liquid or gaseous material is loaded or unloaded a general twin valve system of some kind will be in operation. The general advantages of such systems are:
1. They can be opened and closed very quickly and easily
2. If monitored accurately they are very low maintenance
3. They hold back unwanted fluids with zero leakage
4. They have an industry recognized bubble tight seal
5. They are easy to test because you can readily see if an unwanted material has been isolated.
