Industrial self closing metered taps
Self closing or metered taps are designed for washing hands or showers. The mechanism relies on a spring and negative pressure inside the cartridge to delay water flow. These mechanisms are sensitive to sediment in borehole water and calcium deposits, which is found in all water supplies in Africa. All these valves should be used with potable municipal water only. Warranty of the valves do not cover lime scale buildup inside the valve and damage from wiring due to fine sediment.
metered basin hot & cold mixer tap - DZR brass
The Calderoni metered hot and cold basin pillar tap has the longest flow time of any metered tap we have. Flow time is adjustable between 2-50 seconds depending on water supply pressure. The flow rate can also be adjusted to suit the basin depth and hand washing requirements. The M-100M is manufactured from DZR brass which is essential for South African water characteristics, and specified for all government projects. Temperature can be adjusted with the small lever on the side of the tap. Water temperature is therefore set mechanically and not thermostatically. Maximum hot water must not exceed 70°C. The recommended operating pressure is 0.5-6.0 bar, 2-4 bar being optimal. Low water pressures may prevent the valve’s closing. Standard 15mm male BSP inlet. Dimensions 126 x 126mm. Water reach from center of the base of the tap, 150mm.
