1 TECHNICAL RANGE Pressure Control Valves Fast, Secure, Inexpensive

2 Pressure Cotrol Valves (PCV) The pressure control valves effectively reduce high mains pressure, resulting in less water delivery at taps. The expansion relief pressure control functions are all situated on one spindle, so there is no chance of conflicting settings causing the valve to unnecessarily relieve pressure and thereby waste water L/Min Flow Pressure MF1 20mm 400KPA PA3.132 MF3 22mm 400KPA PA6.342 MF3 15mm 400KPA PA6.341 MF2 15mm 400KPA PA4.331 Closy 20mm 400KPA PA1.1 Flow Pressure MF1 20mm 400KPA PA3.132 MF3 22mm 400KPA PA6.342 MF3 15mm 400KPA PA6.341 MF2 15mm PA KPA Closy 20mm PA KPA

9 PRESSURE CONTROL VALVES - BASIC INSTALLATION REQUIREMENTS CAUTION / WARNING: All installations of products and systems must be in accordance with the applicable SANS regulations, specifications and standards. Installations, servicing and maintenance should be done by accredited service providers only. A. Balanced Pressure Hot and Cold water pressure must be balanced (equal pressure) to all mixers, mixing points, showers and hand showers. This is achieved by taking the cold water supply from the downstream side of the pressure valve. B. Valve Identification kpa valve (Blue cap) 200kPa valve (Black cap) 400kPa valve (Red cap) 600kPa valve (Green cap) CAUTION: The pressure control valve must be compatible with the pressure rating of the hot water cylinder and the temperature and pressure relief valve (safety valve) C. Expansion Relief Drain Pipe Be piped in such a manner to drain downwards Not be interconnected with the safety valve (T&P) drain pipe Not to discharge in the hot water cylinder drip tray Discharge where flow is visible Be protected against frost Have minimal bends/ fittings D. General Requirements All pipes must be flushed clean before putting the system into operation. Waterflow must be in the direction of the arrow marked on the valve body. The valve must be easily accessible for maintenance/ servicing. The relief drain connection must allow for the relief drain pipe to be pulled to one side when removing the cartridge. Allow a minimum distance of ±mm for cartridge removal. Do not install a stop-cock or non-return valve between the hot water cylinder and the pressure control valve. Do not install a stop-cock between the hot water cylinder and the vacuum breakers on the hot and cold sides. Supply pipes adequately sized. Please ensure to make use of copper tube with the installation. Max inlet pressure 2,500kPa. System pressure according to the rating of the hot water cylinder, i.e. only use a 400kPa PCV with a 400kPa rated hot water cylinder and a 600kPa PCV with a 600kPa rated hot water cylinder.

10 PRESSURE CONTROL VALVES - BASIC INSTALLATION REQUIREMENTS E. Valve Valve is pre-set by the factory and does not require any additional adjustments and settings Integral expansion relief valve Integral stainless steel strainer Non-corrosive valve seat F. Connection Types Please take note that PCV ranges consist of a variety of connection types and sizes: 15mm Copper to Copper 22mm Copper to Copper 3/4"BSP Female connection end INSTALLATION OF VALVE AT THE INLET OF THE HOUSE CLEANING AND MAINTENANCE Q. When to service? Insufficient flow rate Continuous drip through the expansion drain Flush the cartridge if any dirt or particles are stuck Replace the cartridge if required Tighten with your hands or a suitable plumbing tool - DO NOT OVERTIGHTEN THE CAP
