Vacuum Break Valves for Drip Lines in Sabah

Draining a line or stopping a pump can produce negative pressure. A suitably selected vacuum-break device admits air to reduce vacuum-related pipe and emitter problems.

How it applies to the water system

High points and sections that drain quickly deserve particular attention. Valve position and air-admission capacity should follow the pipeline profile and the manufacturer installation drawing.

Selection and operating considerations

An air-management valve is not a substitute for an approved backflow-protection arrangement. Review each function separately when the irrigation supply connects to another water system.

Planning the requirement in Sabah

For a Kota Kinabalu building, plant room or water-transfer installation elsewhere in Sabah, send the valve nameplate and photographs of its pipework. Include the intended function, operating records and the connection standard so a replacement or new component can be reviewed properly.

Information to prepare

What should I send SWFI for this requirement in Sabah?

Send the site location, source-water information, operating flow and pressure, and the equipment model or photographs where available. SWFI is based in Kota Kinabalu and can review the requested supply or service scope against the site duty.

Discuss your water-system requirement with SWFI

Sabah Water Filter Industries (SWFI) is based in Kota Kinabalu, Sabah. Share your site details for equipment selection, sourcing or maintenance enquiries. The proposed model and scope depend on the actual water conditions and installation requirements.
