Pressure Sensors Accessories
For part listing and specifications, go to Shop Now
Adjustable Pressure Snubbers
Adjustable pressure snubbers meet a wide variety of media viscosity applications by providing an adjustable snubbing element to suppress pressure surges, improve readability, and prevent wear or damage to delicate instruments.
- Brass or stainless steel bodies available, depending upon pressure media
- ¼" male NPT x ¼" female NPT process connections
- Maximum operating pressure up to 6000 psi
- ASME B40.100 compliant
Manual Block and Bleed Needle Valves
Manual block and bleed needle valves isolate pressure instruments such as gauges, transmitters, transducers, and switches from the sensed media pressure, allowing for easy removal and maintenance of these instruments without shutting down the process. The needle valve allows for precise manual flow rate regulation, while the bleed port relieves downstream pressure without disturbing the permanent piping installation.
- Available in soft seat (6000 psi) and hard seat (10,000 psi) versions
- All stems are 316 stainless steel
- ¼" male NPT inlets, ¼" female NPT outlets
- Maximum operating pressure up to 10,000 psi
Manual Isolation and Throttling Needle Valves
Newest Additions!
- WIKA needle valves for drinking water applications
Manual isolation and throttling valves isolate pressure instruments from the sensed media, allowing quick removal of equipment without shutting down the process. Throttling needle valves provide precise manual flow rate regulation.
- "Slow opening" prevents sudden pressure surges and protects instruments
- 1/4" or 1/2" NPT process connections
- Materials include carbon steel and stainless steel; 316L models are suitable for drinking water and food and beverage applications
- Maximum operating pressure up to 10,000 psi
- ASME B1.20.1 compliant
- Select models are assembled in the USA
Pressure Sensor Installation Accessories
Pressure sensor installation accessories include:
- Mounting brackets
- Protective covers for select models
- M12 cables with pigtails in axial and right-angle designs
- M12 extension cables (connectors on both ends)
- QPS replacement cables
Pressure Snubbers
Pressure snubbers protect sensitive instruments by suppressing pressure spikes commonly found in harsh applications involving reciprocating pumps, compressors, hydraulic presses, or fluid power systems.
- Available in the three standard viscosity classifications: heavy oil, water, and air
- Brass or stainless steel bodies available, depending on pressure media and operating pressure
- Maximum operating pressure up to 20,000 psi
- ¼" male NPT x ¼" female NPT process connections
- ASME B40.100 compliant
Siphons
Siphons protect pressure gauges, transmitters, transducers, and switches from the effect of high-temperature pressure media such as steam.
- Available in brass, carbon steel, or stainless steel for compatibility with different media
- ¼" male NPT process connections
- Maximum operating pressure up to 1650 psi
- Maximum operating temperature up to 680°F (360°C)
