Principle : 
The design of the twinning valve  makes it possible to isolate one of the two safety valves while guaranteeing the continuity of service of the second valve. Thus, the dismantling of a valve for verification, control or replacement is permitted without emptying and degassing the tank.

The use of a dual valve prohibits the isolation of the two valves simultaneously.

Several models of twinning valve exist and several options are possible. Do not hesitate to contact us to tell us about your needs.
