Noshok orifices and snubbers

Click2Contact

Noshok offers a variety of cost-effective orifices and snubbers to protect valuable instrumentation from pulsation and pressure spikes by restricting the flow of rapidly increasing and decreasing pressures.

The press-fit brass orifices or threaded 316 stainless steel orifices are standard with a .012″ ID or .032″ ID, depending on the model. These orifices don’t take up space, as they are inserted inside the NPT.

Piston type and sintered snubbers are also available. The piston type snubbers resist clogging and are self cleaning. They are supplied with five different-sized pistons to ensure the correct amount of snubbing for many applications. They are available in brass and 316 stainless steel in 1/4″ NPT, 1/2″ NPT or 7/16-20 SAE-4.

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 using a corrosion-resistant 316 stainless steel sintered disc, which is held in place by way of a 316 stainless steel set screw. The sintered snubbers allow easy cleaning or replacement of the sintered disc by simply removing the set screw, replacing the disc and then reinserting the set screw, eliminating the need to replace the entire unit if a new disc is required.

Five basic discs are available for each sintered snubber to accommodate specific application needs. Exotic materials or intermediate disc grades are also available on a per order basis.
