Dry-Pipe Control Valve | FP 400Y-DP

Dry-Pipe Control Valve FP 400Y-DP


The BERMAD model 400Y-DP utilizes an elastomeric deluge valve, designed specifically for advanced fire
protection systems and the latest industry standards.

Dry-pipe systems include automatic sprinklers attached to pressurized dry sprinkler piping with supplementary electric monitoring and a Supervised Pneumatic system installed in the same area.

The 400Y-DP admits water into the sprinkler system piping when there is a drop in pressure in the piping due to the opening of one or more fusible head sprinklers.

As an option the 400Y-DP features a rotating valve position indicator available with limit switches for remote valve position monitoring.

System Installation


A typical installation of the BERMAD model 400Y-DP features a pressurized dry sprinkler pipeline with a Supervised Pneumatic System installed in the same area.

Deluge valve actuation is in response to the activation of one or more of the fusible sprinkler heads causing a drop in the dry sprinkler pipeline pressure, triggering the URV relay valve to open the 400Y-DP deluge valve.

When fitted with a limit switch the main valve can send a feedback signal to a remote valve status monitoring system.
