The BERMAD model 43T-06 is an elastomeric hydraulic line pressure operated differential sustaining valve,
specifically designed for advanced fire protection systems and the latest industry standards.
The 43T-06 is equipped with an adjustable differential pilot valve and is used to sustain the differential
between two different points.
When the differential between the two sensed pressures rises above the pre-set value the pilot valve opens the main valve regulating the pressure and keeping the differential at the pre-set maximum.
The 43T-06 is ideal for balanced foam proportioning systems, also as a safeguard for dosing pump flow
As an option the 43T-06 can be fitted with a valve position indicator that can include a limit switch suitable for Fire & Gas monitoring systems.

A typical installation of the BERMAD model 43T-06 uses the automatic valve actuation via a pilot control to open the 43T-06 in response to an increase in differential pressure between two points.
The 43T-06 is ideally suited for regulation in balanced pressure proportioning systems or foam dosing applications.
