• Currently being used in the UHP system to lengthen the life of the high-pressure transducers.
• Gridpath’s pressure snubber units are used to protect against pressure surges, pulsation, and spikes.
• The general design is modelled after an excess flow check valve.
• Operation is similar, as when sudden flow is seen, the poppet will rise, blocking the pressure surge and a small bleed hole in the poppet will allow pressure to slowly equalize.
• When the pressure is equalized, the poppet will then drop back down, allowing normal flow to the gauge or instrument.
• A filter is also used to prevent the very small hole in the plug from clogging.
• Available with either male, female, or male/female ends up to 100,000 PSI.
  

PERFORMANCE
To accurately measure the amount by which a snubber will increase the life of a high-pressure transducer, measurements have to be taken over many months. These readings need to be taken from different transducers introduced into several H/P machine systems.

These tests are currently being carried out, however to date show that at least a 40% increase in transducer life has been achieved. This figure is still rising, as the transducers being tested have not yet failed, and are still working correctly.
