The ETI Dual Valve can be used in a system to obtain the advantages from both ROP and LOP to create the markets best solution. The dual valve uses the LOP detection in the critical fire risk area for fast detection and constant system supervision, and the positive and reliable pneumatic pulse of ROP from the manual actuators thereby greatly reducing the risk of system leaks and prohibitive unscheduled downtime.
