The NABIC Fig 542L has been designed primarily for use where high tightness is required on the discharge side, having a sealed spring cover to prevent the possibility of back pressure leakage through the top of the valve.

The lift is progressively proportional to flow. All wetted parts are manufactured from dezincification resistance materials. Designed and tested to BS EN ISO 4126 -1.
