The Power of Control: Geyser Related Products
A pressure control valve (PCV) is a type of safety valve used to control or balance the water pressure of the hot and cold water supply to baths, showers and basins. It reduces the pressure from the incoming cold water supply to the same pressure of the hot water coming from the geyser.
Advanced Valves’ pressure control and pressure relief valves are proudly designed and manufactured in South Africa, and offer the best value for money. The AD-S 400 is a patented 400kPa Pressure Control Valve, with a metal replacement polymer. The PCV body is moulded in WRAS approved Nylon PA 66 polymer. Each unit is tested and calibrated to ensure individual quality control with a two-year guarantee. There is no better value for money pressure control geyser valve on the market. Our product range is designed to withstand 10 000 kPa water pressure & 180 degrees Celsius temperature, and our PRV, TP, VB and DC products are SABS and SACPS approved. Our advanced geyser valve technology is leading the future of the plumbing industry.
Installation of a Pressure Control and Pressure Relief Valve
When installed inside a dwelling the valve must be attached to a beam with the fastener provided. Hot and cold water must be supplied at equal pressure to mixers and appliances. This is achieved by supplying a dwelling with cold water that is T’ed off after the pressure control valve and not before.
A drip tray is required to be installed. All components, including the pressure control valve, are to be installed above the drip tray. Due to expansion of water during the heating cycle the relief valve will release excess pressure. Normal overflow is between 2 to 4 litres per day.
The expansion overflow pipe is to be secured and insulated to guard against movement and freezing. Expansion valve overflow is to be piped to the exterior of the building and piped at a decline. Carefull consideration should be given to its positioning. Hot water has safety implications and excess overflow can cause damage to property.
Vacuum breakers are to be installed as per diagram.
Cyril Ramaphosa speaks indirectly about the Value of Advanced Valves
“Proudly South African must be a reality. We need to demonstrate that buying local is about investing in quality and sustaining local business and investing in our people by keeping the jobs here at home.”
