The perfect solution for effective control of service line pressure

Ratio valves are manufactured from high grade materials to provide reliable operation and a high level of corrosion resistance. Not only are spare parts available but these valves are backed by a full maintenance service. Philmac’s range of ratio valves are designed to handle situations where reliable, controlled high pressure operationis essential.

  • 1

    Maintained Pressure

    Under no flow conditions the downstream pressure is maintained because the valve remains closed and it will not open until the downstream pressure drops when installed in a fixed head system.

  • 2

    Simple Sealing Action

    Because the valve relies on only one moving part it means the valve has high reliability and shuts off when required. There are no internal ports which can become blocked or springs that can become corroded.

  • 3

    Connection Flexibility

    To make installation easy Philmac offer both threaded (up to 2”) and flanged connections (up to 6”). Flanged connections are available in almost any flange pattern including DIN, ANSI, BS or AS standards.

  • 4

    Tamperproof

    There are no external regulators or pilot tubes which can be tampered with so once the valve is installed it will continue to operate at its pre set ratio.

  • 5

    Quality Materials

    The screwed ratio valves are made from DZR brass meaning the valves have a high resistance to corrosion in solid and water environments. The flanged ratio valves are manufactured from gunmetal which again provides a high degree of corrosion resistance and strength. Please note different materials can be used if specific application requirements require it.

  • 6

    Multi-position Installation

    The valves have been designed to work in either vertical or horizontal position for flexible installation.

  • 7

    High Pressure Shut off

    The ratio pressure reducing valves are rated to 35 bar at 20 degrees centigrade. However they can be rated to 50 bar if required by specific application.

  • 8

    High Flow Rates

    Due to the internal design when the valve is fully open it allows full flow of water.

  • 9

    Serviceable

    The valves have been designed to be fully serviced and repair kits containing all the seals, o-rings and instructions are readily available.
