2.2 VALVES

  1. An ABS ball valves with metric sizes DN 15 - 100 mm, shall be Georg Fischer Piping Systems Type 546 with true double union design manufactured by Georg Fischer Piping Systems in accordance with EN ISO 16135. Incorporated into its design shall be a safety stem with a predetermined breaking point above the bottom O-ring, preventing any media leaking in the event of damage. The valve nut threads shall be buttress type to allow fast and safe radial mounting and dismounting of the valve during installation or maintenance work. Seats shall be PTFE with backing rings creating self-adjusting seals and constant operating torque. Backing rings and seals shall be EPDM or FPM. The handle shall include in its design an integrated tool for removal of the union bush. Union bush shall have left-hand threads to prevent possible unscrewing when threaded end connectors are removed from pipe.

  2. All ABS diaphragm valves, metric sized, shall be either:

    • Type 314 (true double union design, DN 15-50), or
    • Type 315 (spigot design, DN 15-50) or

PART 3 - EXECUTION

3.1 TESTING

The system shall be tested in accordance with the manufacturers’ recommendations.

Following is a general test procedure for Georg Fischer plastic piping. It applies to most applications. Certain applications may require additional consideration. For further questions regarding your application, please contact your local GF representativeAll piping systems should be pressure tested prior to being placed into operational service.

  1. All pressure tests should be conducted in accordance with the appropriate building, plumbing, mechanical and safety codes for the area where the piping is being installed.

  2. When testing plastic piping systems, all tests should be conducted hydrostatically and should not exceed the pressure rating of the lowest rated component in the piping system (often a valve). Test the system at 150% of the designed operational pressure, i.e.: If the system is designed to operate at 80PSI, then the test will be conducted at 120PSI.

  3. When hydrostatic pressure is introduced to the system, it should be done gradually through a low point in the piping system with care taken to eliminate any entrapped air by bleeding at high points within the system. This should be done in four stages, waiting ten minutes at each stage (adding ¼ the total desired pressure at each stage).

  4. Allow one hour for system to stabilize after reaching desired pressure. After the hour, in case of pressure drop, increase pressure back to desired amount and hold for 30 minutes. If pressure drops by more than 6%, check system for leaks.

    Note: If ambient temperature changes by more than 10°F during the test, a retest may be necessary.
