Technical Data Summary for Air Pulse Valve System

1. Timing and Electrical Characteristics
- Maximum Air Pulse Creation Time ranges from 1.00 ms to 1.90 ms depending on conditions.
- Time to Start Flow varies between 1.25 ms and 1.85 ms.
- Time to Start Exhaust ranges from 1.40 ms to 1.90 ms.
- Peak Current values are consistently 40 or 80 amps.

2. Valve Model and Grease Specifications
- Valve models are identified with codes such as 31A-XXX-TFAX-XXX, 31A-XXX-TFBX-XXX, and 31A-XXX-TFCX-XXX.
- Grease types include Food Grade Grease and Standard Grease.
- Food Grade Grease models include S041, S042, S043, S044, S045, and S046.
- Standard Grease models include S041, S042, S043, and S044.

3. Flow and Pressure Parameters
- Flow coefficient (Cv) values range from 0.03 to 0.06.
- Differential Air Assist pressures are typically 24 psi, with some values at 6.5 psi.
- Inlet pressure is consistently 24 psi.

4. Electrical Parameters
- Voltage is 24 VDC.
- Resistance values vary between 0.25 Ohms and 0.70 Ohms.

5. Summary of Key Parameters
| Parameter | Range/Value |
|---------------------------|----------------------|
| Maximum Pulse Time (ms) | 1.00 - 1.90 |
| Time to Start Flow (ms) | 1.25 - 1.85 |
| Time to Start Exhaust (ms)| 1.40 - 1.90 |
| Peak Current (Amp) | 40 or 80 |
| Flow Coefficient (Cv) | 0.03 - 0.06 |
| Differential Air Assist (psi) | 6.5 or 24 |
| Inlet Pressure (psi) | 24 |
| Voltage (VDC) | 24 |
| Resistance (Ohms) | 0.25 - 0.70 |

6. Observations and Recommendations
- The data indicates precise timing control for air pulse generation is critical.
- Selection of grease type (food grade vs standard) depends on application requirements.
- Electrical parameters must be matched to valve model for optimal performance.
- Maintaining inlet pressure at 24 psi is essential for consistent operation.

This summary consolidates the key technical specifications and operational parameters for the air pulse valve system, facilitating informed decision-making for design, maintenance, and application.
