Weiss Pressure Snubber | PSNS-50 | 1/2″ NPT | 303 Stainless Steel

Product Description

The PSNS-50 acts as a precision dampener between the process line and the pressure gauge. The “PSNS” designation identifies this as a Stainless Steel snubber, while the “50” denotes the robust 1/2″ NPT connection size.

In the UAE’s industrial and mechanical sectors, equipment like high-pressure booster pumps and rapid-acting solenoid valves can create massive pressure spikes (fluid hammer). These spikes cause the gauge needle to vibrate (pointer flutter) and can lead to permanent internal damage. The PSNS-50 utilizes a micro-porous sintered metal filter to restrict the flow of fluid, “smoothing” the pressure wave so the gauge provides a steady, accurate reading. The use of 303 Stainless Steel ensures the snubber can handle corrosive fluids and high-temperature environments where brass models would fail.

Key Features

• 303 Stainless Steel Construction: Provides superior strength and excellent resistance to corrosion, making it suitable for treated water, steam, and industrial chemicals.
• Precision Pulsation Dampening: Eliminates pointer flutter and protects the internal Bourdon tube from mechanical fatigue and shock.
• Micro-Porous Filter Element: Features a high-quality sintered metal disc that restricts rapid pressure changes while allowing accurate static pressure monitoring.
• 1/2″ NPT Industrial Connection: Features a male-to-female configuration (1/2″ MNPT x 1/2″ FNPT) for direct installation on main piping headers and heavy-duty gauges.
• Extreme Durability: Designed to handle significantly higher pressure and temperature limits than standard brass snubbers.

Frequently Asked Questions

• Q: Why use a 1/2″ Stainless Snubber (PSNS-50) over a 1/4″ Brass model?
  • A: The 1/2″ connection is required for larger industrial gauges and main process headers. Stainless steel (303SS) is necessary when the fluid is corrosive, the temperature is high (e.g., steam), or the pressure exceeds the limits of brass.
• Q: Can this be used on steam lines?
  • A: Yes, the PSNS-50 is excellent for steam, but it should ideally be installed after a syphon (between the syphon and the gauge) to provide the best possible protection for the instrument.
• Q: Does it require maintenance?
  • A: In very clean systems (like chilled water), it is maintenance-free. In dirty systems, the internal porous element can eventually clog; however, the stainless steel construction allows for cleaning with solvents if necessary.
