Pressure Differential Reducing Control Valve (PDRCV) FP 42T-06


The BERMAD model 42T-06 is an elastomeric hydraulic line pressure driven differential reducing valve, specifically designed for advanced fire protection systems and the latest industry standards.

The 42T-06 is equipped with an adjustable differential pilot valve and is used to maintain a set pressure differential between two different points.

When the differential between the two sensed pressures approaches the pre-set maximum the pilot valve starts to close the main valve regulating the pressure and preventing the differential from rising further.

The 42T-06 is ideal for balanced foam proportioning systems, also as a safeguard for dosing pump flow overload.

As an option the 42T-06 can be fitted with a valve position indicator that can include a limit switch suitable for Fire & Gas monitoring systems.

System Installation

A typical installation of the BERMAD model 400Y 42T-06 features valve actuation via pilot control to regulate the 42T-06 in response to an increase in differential pressure between two points.

The 42T-06 is ideally suited for regulation in balanced pressure proportioning systems or foam dosing applications.
