PT | Kele | Pressure

The 47B, 47S, 747B, 747S, PT snubbers and pigtail snubbers from Kele will stop shocks and pulsations that damage pressure instruments. These reduce maintenance expense, calibration costs and repair costs. They will also assure accuracy of the instruments and the readings, increase life of instruments, and prevent false operation of control equipment. Kele offers two types of pressure snubbers; piston and porous. The Model 47 Snubber incorporates a piston that moves up and down inside of an internal tube within the snubber. This piston movement, caused by the shocks and pulsations of the fluid, dampens the effect of these pulsations. It is available in three piston sizes: #02, #2, and #3. Piston #2 is installed in the factory in the snubber. It is used for most applications, such as water, air, and steam. The #3 piston is used for a greater snubbing effect, while the #02 piston is used for relatively thick fluids or low pressure water applications. The Model 747 Snubber is a porous snubber and a low-cost alternative to piston snubbers. There are no moving parts. It uses a porous material to dampen the effect of shocks and pulsations. The Model 747 is available in stainless steel and brass, and it is ordered based on the application, gases or liquids. In steam applications, the temperature of the steam is higher than the maximum operating temperature of most pressure transmitters, which is why the Model PT is ideal for steam pressure monitoring. The Model PT steam pigtail syphon will protect a pressure transmitter applied to steam systems. See the 'Technical Reference' section in the Kele catalog for more detailed information. The Model PT is constructed of steel and is suitable for steam pressure to 250 psig (1724 kPa) 400 degrees F (204 degrees C).
