OPERATION (BMS)

The pressure of the network to be protected pushes the dia-

phragm, piston or bellows.

The force resulting from this opposes the force (adjustable)

stage trigger

Releasing by min. pressure

Releasing by max. pressure

coming from the set-point spring.

When pressure varies, the detection rod moves and provokes

releasing by max. or min. pressure.

CONNECTIONS (BMS)

On the mechanism box : 2 H M6x16 screws (code 402018)

BM sealing : Flat O-ring and tight shut O-rings

On the manometric box : 1/4" NPT screwed

Recommended tube: 8/10 mm

The sensing line must be connected downstream of the regulator.
