PHILMAC

With over  40 years of proven usage, Philmac ratio pressure reducing valves accurately control service line pressure in fixed head water systems. Pressure is reduced by ratio to protect appliances from damage caused by excess pressure. The valves also protect pipework by reducing surge and water hammer.

Since those early days Philmac has developed a worldwide reputation for innovative manufacturing. A reputation built on decades of experience and investment in cutting-edge technology – as evidenced by our recent $10 million machinery upgrade. Our products are manufactured in our state-of-the-art plant in Adelaide, South Australia. This award-winning facility features some of the most advanced injection moulding and robotic assembly equipment available.
