Pneumatic loading system 714

Product description
Electric-pneumatic supplementary loading system designed for safe operation up to 97% of the maximum permissible operating pressure (PB). Type 714 enables precise control of safety valve loading to minimize leakage, noise and wear while maintaining full tightness up to the set pressure. Suitable for industrial process installations requiring accurate overpressure protection and improved operational availability.

Key benefits

• Allows operation closer to set pressure (up to 97% PB), increasing process productivity
• Reduces media loss through shorter opening and closing times of safety valves
• Lowers noise emissions due to faster valve actuation
• Ensures complete tightness up to set pressure, maintaining seal during pressure peaks below set point
• Decreases wear on the safety valve by preventing simmering prior to actuation

Applications & Industries

• Chemical industry
• Energy and power plants
• Pulp and paper industry
• Urea and fertilizer production

The optimal solution for

• Operation up to 97% of set pressure
• Maintaining complete tightness to set pressure
• Systems with back pressure greater than 50%
