Supported Applications
The Dwyer Series A-169/A-170 Instrumentation Siphons protect pressure instruments in high temperature applications. Water held in the 180° coil prevents steam from contacting the instrument, making them suitable for use with pressure gages and instrumentation where the process media temperature exceeds the rating of the instrument.
These siphons are designed for service with compatible liquids and gases.
Operating Conditions & Performance
The series supports specific pressure limits tied to material construction, schedule thickness, and operating temperature. According to the model chart:
- A-169-C (Carbon steel SCH 80): 500 psi @ 680°F
- A-169-D (Carbon steel SCH 80): 500 psi @ 680°F
- A-170* (316 SS SCH 80): 2307 psi @ 200°F
- A-170-A (316 SS SCH 40): 500 psi @ 680°F
- A-170-B (316 SS SCH 40): 500 psi @ 680°F
Note: Model A-170 is not RoHS certified.
Configuration Options
The series offers configurable options across materials, process connections, and dimensions to accommodate different installation requirements.
Materials of Construction
- Carbon steel: Available in SCH 80 (Models A-169-C, A-169-D).
- 316 SS: Available in SCH 80 and SCH 40 wall thicknesses (Models A-170 series).
Process Connections
- Male NPT connection: Offered in 1/4" or 1/2" sizes.
Dimensions and Weight
Detailed dimensional data is provided for specific models. For example, Model A-169-C features a coil diameter of 1-13/64 [30.39], coil width of 2-7/16 [61.87], and straight length of 5-3/32 [129.54].
- Weight: 1/4" NPT models weigh 8 oz (226.8g); 1/2" NPT models weigh 25.6 oz (725.75 g).
Key Product Differences
The Series A-169 and A-170 differ primarily in wetted material composition, which dictates the pressure rating at specific temperatures.
- Series A-169: Constructed from Carbon steel SCH 80. Rated for 500 psi @ 680°F across both 1/4" and 1/2" NPT male connections (Models A-169-C, A-169-D).
- Series A-170: Constructed from 316 SS. Offers higher pressure capability at lower temperatures or standard high-temp ratings depending on schedule thickness.
