Details

Saferise® is a double-orifice air valve with integral engineered surge anticipation and alleviation mechanism. Designed to overcome potentially damaging effects of hydraulic surges associated with water boosting systems in high-rise buildings, vacuum prevention on pump failure and column separation. Saferise® allows the efficient intake of bulk air during the draining cycle while accurately controlling the discharge speed during the charging cycle.
