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.

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 serviceproviders only.

CAUTION:The pressure control valve must be compatible with the pressure rating of thehot water cylinder and the temperature and pressure relief valve (safety valve)

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 thedownstream side of the pressure valve.

A. Balanced Pressure

B. Valve Identification

100kPa valve (Blue cap)200kPa valve (Black cap)400kPa valve (Red cap)600kPa valve (Green cap)

C. Expansion Relief Drain Pipe

Be piped in such a manner to drain downwardsNot be interconnected with the safety valve (T&P) drain pipeNot to discharge in the hot water cylinder drip trayDischarge where flow is visibleBe protected against frostHave 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 whenremoving the cartridge. Allow a minimum distance of ±100mm for cartridge removal.Do not install a stop-cock or non-return valve between the hot water cylinder and the pressurecontrol valve.Do not install a stop-cock between the hot water cylinder and the vacuum breakers on the hotand 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 witha 400kPa rated hot water cylinder and a 600kPa PCV with a 600kPa rated hot water cylinder.
