Overview of WSAA

The Water Services Association of Australia (WSAA) is the peak industry body representing

the urban water industry. Our members provide water and sewerage services to over 20

million customers in Australia and New Zealand and many of Australia's largest industrial

and commercial enterprises.

Based around our vision of 'customer driven, enriching life', WSAA facilitates collaboration,

knowledge sharing, networking and cooperation within the urban water industry. We are

proud of the collegiate attitude of our members which has led to industry-wide approaches

to national water issues.

WSAA can demonstrate success in the standardisation of industry performance monitoring

and benchmarking, as well as many research outcomes of national significance. The WSAA

Executive retains strong links with policy makers and legislative bodies and their influencers,

to monitor emerging issues of importance to the urban water industry.

WSAA was formed in 1995 as a non-profit organisation to foster the exchange of information

between industry, government and the community, and to promote sustainable water

resource management.

The urban water industry is committed to anchoring its services to customers' values, and

to enrich communities where water services have broad economic, environmental and social

values. In line with this our main activities focus on four areas:

1. influencing national and state policies on the provision of urban water services and

sustainable water resource management

2. promoting debate on environmentally sustainable development and management of

water resources and the community health requirements of public water supplies

3. improving industry performance and establishing benchmarks and industry leading

practices for water service processes; and

4. fostering the exchange of information on education, training, research, water and

wastewater management and treatment and other matters of common interest.

1 EXECUTIVE SUMMARY

CMW-BVA Valves Pty Ltd trading as Challenger Valves and Actuators, located in

Shepparton, Victoria, was established in 1984. The company is a distributor of valves and

actuators, providing products including butterfly, gate, knife gate, ball and check valves, in

various materials, for a wide range of industrial processes and applications. The Shepparton

site is ISO 9001 certified. Challenger has additional warehouses in Perth, Brisbane and

Newcastle.

The range of Karon Resilient Seated Swing Check (RSSC) valves is manufactured in China

for Challenger and is product certified for compliance with AS 4794:2001 – Non-return valves

for waterworks purposes – Swing check and tilting disc.

The ductile iron polymeric coated flanged valves submitted for appraisal are rated as PN16

in sizes from DN 80 to DN 375 and are operated by a lever arm and counterweight. A free

acting version is also available. Flanges are to AS/NZS 4087 Figure B5.

Karon RSSC valves are utilised for the prevention of flow reversal in pipeline systems. The

valves incorporate an EPDM encapsulated flap and are suitable for use in potable and

recycled water supply and pressure sewer networks. The operation of the valve is fully

automatic and the flow is unidirectional.

The RSSC’s are not suitable for high unbalanced heads. The valves can be serviced or

rehabilitated in-situ subject to access.

The Karon resilient seated swing check valves included in this appraisal meets the

requirements of WSA PS-264 – Non-Return (Reflux) Valves for Pressure Applications –

Water Supply and Sewerage and are therefore considered as ‘fit-for-purpose’.

1.1 Recommendations

It is recommended that WSAA members, subject to any specific requirements of the member,

accept or authorise the Karon RSSC, as detailed in this report, for use in potable and

recycled water supply or pressure sewer networks subject to relevant pipeline design,

installation, acceptance testing and commissioning are in accordance with the

manufacturer’s recommendations and the relevant WSAA Codes.

2 THE APPLICANT

COPYRIGHT

2.1 The Manufacturer

This product is manufactured exclusively for Challenger by Shanghai Karon Valves

Machinery Co. Ltd. which is located at No. 88, Lianxing Road, Lianxing Village, Anting Town,

Jiading District, Shanghai, 201802, P. R. China. The site has a Quality Management System

certified for compliance with ISO 9001:2008.

The Karon RSSCs are assembled and tested at the above facility and components are

sourced locally in accordance with Karon specifications. Polymeric coatings are applied in-

house to the ductile iron components, utilising the fluidised bed method.

Shanghai Karon Valves Machinery Co., Ltd. was established at Shanghai in 1991, primarily

to manufacture valves for the water and sewage industry. The Taiwanese Company has

more than 40 years’ experience in the manufacture of a wide range of valves for the water,

wastewater, petrochemical and power industries. The company operates four manufacturing

plants, three based in the Shanghai area and the original factory based in Taiwan.

The company produces a wide range of industrial valves for the water industry up to and

including 3 metres in diameter. The company exports globally with major markets in USA,

South America, Europe and the Middle East.

For more information see: www.karon-valve.com.

3 THE PRODUCT

The Challenger resilient seated swing check (RSSC) valve range carries the trade name

“Karon” and has been certified by SAI Global as complying with AS 4794:2001 – Non return

valves – Swing check and tilting disc.

RSSC valves are utilised for the prevention of flow reversal in pipeline systems.

The RSSC valves submitted for appraisal are in sizes from DN 80 to DN 375 and are

operated by a lever arm and counterweight. A free acting version is also available.

Flanges are to AS/NZS 4087 Figure B5.

The ductile iron components are polymeric coated in accordance with AS/NZS 4158.

The RSSC valves incorporate an EPDM encapsulated flap and are suitable for use in potable

and recycled water supply or pressure sewer networks. The operation of the valve is fully

automatic and flow is unidirectional. The EPDM encapsulated disc prevents corrosion,

ensures drip tight closure and ensures a long life.

The RSSC valve uses positive pressure to hold the disc open to avoid fluctuations. The full

bore non-clogging design restricts debris accumulation and reduces head loss. An extended

shaft design allows for installation of limit switches. The bonnet access allows for cleaning

and maintenance without having to remove the valve from the pipeline.

The Karon RSSC valves incorporate lifting lugs and support feet. An option to provide ‘no

flow proximity sensors is available. See the Challenger brochure in Appendix A or visit

www.challengervalves.com.au for details.
