Hattersley's range of WRAS Approved static balancing valves includes Double Regulating Valves and Fixed Orifice Double Regulating Valves. The integral fixed orifice design offers greater accuracy than the variable orifice design valves, makes set-up easier and involves fewer connections resulting in lower installation costs.

Available in medium and low flow versions, Hattersley's static balancing valves offer positive flow control at all handwheel settings.
