Product Overview
This repair kit is specifically engineered for AUTEL AE1818B / AE1822B series pulse valves, serving as an essential replacement part to maintain the high efficiency of baghouse dust collector cleaning systems. As the core actuating element, the diaphragm’s response speed and sealing integrity directly impact system energy consumption and emission levels. This M/D20 diaphragm repair kit, manufactured with premium polymer compounds and precision vulcanization processes, ensures stable and reliable opening/closing actions under demanding operating conditions.
Operating Principle & Technical Background
In a pulse jet system, the solenoid pilot valve rapidly exhausts the air above the main diaphragm. The resulting pressure differential forces the main valve to open instantly, releasing a high-pressure air pulse for cleaning. Upon pilot valve de-energization, air re-enters the upper chamber through the bleed hole, balancing pressure and enabling a smooth, tight valve closure. This diaphragm’s optimized dynamic characteristics guarantee precise valve cycling under high-frequency and high-pressure operations, minimizing compressed air consumption.
Core Materials & Customization Options
To accommodate various media and temperature conditions, we offer flexible material combinations. The standard configuration and available options are detailed below:
| Component | Standard Material (Characteristics) | Customizable Options (Application Scenarios) |
|---|---|---|
| Diaphragm Body | TPE (Thermoplastic Elastomer) • Excellent flex-fatigue resistance • Good oil and sealing performance • Temperature Range: -20°C to +80°C |
• NBR: Superior oil resistance • EPDM: Outstanding weather, ozone, and steam resistance • FKM (Viton®): High-temperature resistance (up to 200°C) and chemical resistance |
| Seat Washer | Integrated with diaphragm body | Available in Nylon, PTFE, etc., for enhanced erosion or corrosion resistance as needed. |
