TA-956 DFOL

The Tormene TA 956 DFOL is a Fail Open type pressure regulator, this means that the main valve will move to the fully open position in the event of a diaphragm rupture of the main valve, rupture of pilot diaphragm or supply pressure to pilot is not available.

This pressure regulator is based on a special diaphragm that acts as the control medium/valve itself.
