Surge Arrestor Valve 

CLA-VAL Model Vent-A-Riser Surge Arrestor (formerly Vent-O-Mat RBXb) incorporates as standard:

Automatic Surge Protection - The “always on” controlled air release function prevents hammer and surges in the line when filling or refilling pipes.

Vacuum Protection - The large orifice admits air in the riser to prevent vacuum and damage to pipes and fittings from occurring when the booster set is down (powered off).

Effective Air Release - The small orifice functionality allows air to be removed from the system while the system is pressurised, preventing the formation of air locks in the system and keeping the system running efficiently.

Guaranteed performance - Every valve is pressure tested to ensure trouble free operation.
