Description
This DI Double Regulating Balancing Valve (Bolted Bonnet with Pressure Test Cock) from Leader covers 50 mm to 600 mm at PN 16. Used to commission chilled and hot water circuits so each terminal receives its design flow. Fitted with test points, they allow flow to be measured and locked at the commissioned setting. The bolted bonnet allows the gland to be repacked and the internals inspected without cutting the valve out of the line. Flanged connections allow the valve to come out for overhaul with the pipework left in place. Size-by-size catalogue numbers and pricing appear in the table above.
