Kolling Self-Regulating Valve is designed and constructed to conform fully to BS5041:pt1 1987 which does not require a return pipe. Valve shall be of the rising stem inside screw type having the actuating thread within the bonnet. The hand wheel has a minimum clearance of 40mm between any parts of the valve vertically below. The valve body is able to withstand a hydrostatic pressure of 30 bars and the seat for 22 bars. The flow rate is 8.5 +/- 0.5 L/Second at the inlet pressure of 7.5 bars and up to 20 bars. The mechanism for outlet pressure adjustment is fitted with a locking/clamping device to maintain the initial setting.

Valve fully complies with all the operational requirements of the standards without alteration of initial setting. (e.g Inlet pressure from 5 bars up to 20bars but outlet pressure shall remain at a constant pressure without further adjustment). Material for valve shall be LG2 or LG4 gunmetal for body and copper alloy for bonnet and stem.
