Orders placed by 3-00 pm have same working day dispatch and prompt delivery, normally next working day delivery, on selected models only.

Currently we are experiencing issues in achieving next working day delivery in some areas due to HGV driver shortages.

Product Information

Saferise Double Orifice Air Valve

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.
