SPECIFICATION

Scope

This specification outlines guaranteed features and performance of the valve. Due to ongoing improvements,

the manufacturer reserves the right to alter the specifications without prior notification.

Compliance to Standards:

SAA MP52 Spec 6.30

IEC 730-2-1 & IEC 730-2-8

AS4020

BS6920.1 & BS6290.2

AS C3169

AS1722

AS3169

ASTM B 117

UL94

IEC 695-2-1

Functional Requirements:

Standard piping configurations are made to the inlet of the valve by connecting via the ¾” BSP

male thread connection. The outlet of the valve is available in various configurations. These being

either 3/4" BSP male thread, 10.5mm barb, 1/2" barb or 3/4" barb. The barb outlets are intended to

be connected with a flexible hose. This product has been designed to meet all requirements

enabling it to be connected to a mains water supply provided it meets the Hydraulic Performance

Criteria stated in this specification.

For best performance especially at low pressures, the valve should be mounted in a horizontal

position with the solenoid standing in an upright position.

Standard electrical connections are made via the two 6.3mm tabs protruding from the valve. It is

advisable to ensure that the electrical receptacles connecting the tabs are insulated.

SPECIFICATION

Minimum static bursting pressure > 6.5 Mpa (65 bar), reached through a gradual pressure increase spread

over 20 seconds starting from atmospheric pressure.

Resistance to external pressure peaks (water hammer peaks)

The valve will withstand 100 cycles of 5.0 Mpa transient peaks (peak width of 200ms)

Resistance to pulling out

The coil on the appliance valve does not move or pull out from its original position when subjected to a

gradually applied force which is parallel to the plunger housing spindle of no less than 50N (5.1 Kg).

Strength of coupling thread

With a minimum of 5 full threads engaged, the inlet and outlet coupling threads do not strip or break

when subjected to a tightening torque of 30Nm.

Potable water contact

All non-metallic materials in contact with water have potable water certification to AS4020, and/or

BS6920 parts 1&2, and/or current approvals with FDA & WRC.

All metallic materials in contact with water, comply with AS4020, or contain not more than 4.5% lead

(0.1% lead for solders) and 0.05% cadmium.

Corrosion resistance of stainless steels

The stainless steels pass the salt spray fog test according to ASTM B 117 salt spray fog test. Stay time

100 hours. After having been dried in ambient temperatures, there are no rust spots present. A small

yellow discolouration is acceptable.

Solenoid resistance to fire

Solenoid coil former and encapsulant are rated to UL94 – V0 and/or Glow wire-

IEC 695-2-1, 960˚ C

Resistance to arc tracking / earth leakage

Solenoid assemblies are flash tested to 3.3 – 3.5kV ac, 50 Hz between earthed parts and live parts of

opposite polarity.

SPECIFICATION

The valve operates correctly between 20Kpa and 1250kPa (0.2 – 12.5 bar), at the inlet of the valve.

Opening pressure drop

The valve is designed to comply with IEC730-2-8 clause 18.101.3

Operating Pressure Rise (Water Hammer Peak)

Static Pressure ranges = 20 kPa to 1250kPa (0.7 bar – 12.5 bar)

Supply pipe velocity range =1.2 m/s to 6.5 m/s

Immediately after closure, the pressure peak is not to exceed 115% of the initial static pressure condition.

Opening Response Time

Flow established within 0.5 sec of power application

Closing Response Time

Within 0.5 sec after power is removed

Leaking under pressure

Max seepage admitted in the whole of the pressure range is 10ml/12 Hours

Dynamic Life

10 valves are sequentially cycled. One valve on for 3 seconds all valves off for 3 seconds, next valve on

for 3 seconds and so on.

1(one) cycle is complete after all 10 valves have been opened and closed.

The valves survive 25,000 cycles at a water temperature of 80˚ C and a static pressure of 1500 kPa (15

bar)

Static Life

As per Australian standard SAA MP52 Specification No. 030, clause 6.30.7, which is:

Plastic bodied valves shall be capable of withstanding a hydrostatic test pressure of 3.0 +0.5 Mpa for 60

+5 mins at the manufactures stated maximum operating temperature without leakage.

SPECIFICATION

In certain installations there is the possibility of trapped excess pressure in the line between the valve inlet

and supply inlet. This condition may arise when other valves or taps shut off and cause transient high

pressure peaks through out the plumbing system.

The valve will open in the following adverse condition:

Rated voltage - 10%

Coil temperature = 25 ± 5˚ C prior to power on

Trapped pressure released = up to 2000kPa (20 bar)
