NOSHOK orifices and snubbers from AMS Instrumentation and Calibration are cost effective and protective valuable instrumentation from pulsation and pressure spikes by restricting the flow of rapidly increasing and decreasing pressures.
Both press-fit brass orifices and threaded 316 stainless steel orifices are available on all NOSHOK pressure gauges and most NOSHOK transducers. Depending on the model, they are standard with a .012" I.D or .032" I.D. Inserted inside the NPT, these orifices don’t take up space, and they are an economical solution for managing pressure fluctuations in dynamic applications.
The NOSHOK piston gauge snubbbers and sintered snubbers are supplied with five different sized pistons to ensure the correct amount of snubbing for virtually every application. They are available in brass and 316 stainless steel in 1/4" NPT, 1/2" NPT or 7/16-20 SAE-4.
The piston gauge snubbers resist clogging and are self cleaning, and the sintered snubbers increase gauge readability by smoothing out pressure surges, pulsations and spikes, and eliminate instrument failure due to pressure shock.
Snubbing action is achieved by utilizing a corrosion resistant 316 stainless steel sintered disc, which is held in place by way of a 316 stainless steel set screw. Unlike the competitor’s crimped method, NOSHOK sintered snubbers allow simple cleaning or replacement of the sintered disc by simply removing the set screw, replacing the disc and then re-inserting the set screw. This efficiency eliminates the need to replace the entire unit if a new disc is required, and this built-in versatility greatly increases the snubber’s longevity, durability and dependability.
Special materials or intermediate disc grades are also available on a per order basis and five basic discs are available for each sintered snubber to accommodate specific application needs. These snubbers provide long service life with no moving parts to wear out.
