Foxboro 69TA-2RH Pneumatic Filter Pressure Reducing Valve

1. Brand and Model Interpretation

Foxboro (now part of Schneider Electric) 69TA-2RH series integrated pneumatic filter pressure reducing valve (air source pressure regulating filter), mainly used to provide clean and stable air source for valve positioners and pneumatic actuators:
Segmented code meaning:

1. 2: Output pressure regulating range 0~6 bar (0~90 psi/0~600 kPa);
2. S: Equipped with an integrated filter structure, featuring both air filtration and pressure regulation functions;
3. K: Standard DN50 three-scale pressure gauge (with intuitive readings in kPa/bar/psi units)

3. Core Functions

1. Dual Air Source Processing**: Filters dust and condensate water impurities in compressed air, stabilizes output pressure, and avoids damage to downstream valve positioners and pneumatic actuators due to pressure fluctuations;
2. On-site Direct Pressure Adjustment**: Equipped with multiple unit pressure gauges, allowing for on-site adjustment of output air pressure without the need for external instruments;
3. Easy Maintenance**: The filter cup at the bottom supports manual discharge, and the filter element can be replaced separately, reducing maintenance costs;
4. Strong Adaptability to Working Conditions**: Wide temperature design is suitable for high-temperature and dusty industrial sites such as petrochemicals, power plants, and metallurgy. 4. Typical Application Scenarios

In the self-control loops of petrochemicals and power plants, it serves as a pre-treatment air source for Foxboro/SRP series valve positioners, pneumatic regulating valves, and pneumatic interlock actuators; it is often used in conjunction with previously queried ICS Triplex safety system and ABB RTU measurement and control cabinets to build a complete process control link.
