Bridgman Attenuator
Grace Precision Products offers high pressure (60KSI) and ultra-high pressure (90KSI) attenuator assemblies. While these are very mundane looking pieces of hardware, the amount of engineering required to produce a safe and long-lasting product is astonishing. And, while their mission is simple, which is to minimize pressure drop while the intensifier shifts, it is also critical in order to provide the quality of cut that waterjet is known for. The Extreme Safety
attenuators are GPP’s own patented design, while the Bridgeman attenuators are one of the oldest, and therefore most recognized designs in the waterjet industry.
Traditional Bridgman Seal Attenuators
Grace Precision Products offers traditional Bridgman seal attenuators that have been a staple in the waterjet industry since its inception. The pressure-energized seal has proven itself over decades of use to be a reliable (although, non-reparable) design.
Features:
- Attenuator body and head wetted bores are mechanically treated for long life
- Every assembly is pressure tested to 94,400 psi (6,509 bar) to seat the Bridgman seal and ensure the integrity of the components
- 66,000 psi (4.550 bar) operating pressure at 32°-140°F (0°-60°C)
- Assemblies are offered in 1.0 , 0.95 and 0.60 Liters capacities
- Components per the Pressure equipment directive (PED) press tested to 1.43x operating or 94,000psi
