Rubber Bladder NXQA-10 31.5-L-EH & YSF9-55 130DSKJTHB

Rubber Bladder NXQA-10/31.5-L-EH & YSF9-55/130DSKJTHB Valve Safety Measures
Product Introduction
The Rubber Bladder NXQA-10/31.5-L-EH is a core component for transformer pressure stabilization systems, coordinating with the pressure relief valve YSF9-55/130DSKJTHB to prevent false activation. Produced by YOYIK, it integrates reliable sealing and pressure resistance, laying a foundation for transformer safe operation.

Key Measures to Avoid False Activation of YSF9-55/130DSKJTHB
- Accurate Pressure Setting: Base settings on the transformer’s rated pressure (e.g., 130 kPa relief pressure). Slowly increase pressure during commissioning; ensure activation only at 130 kPa, not below 120 kPa, to avoid false triggers from oil temperature fluctuations.
- Enhance Vibration Resistance: Utilize the valve disc’s damping device. Fix the valve body firmly, lock the bracket with double nuts to prevent shaking caused by transformer vibration.
- Reliable Reset & Regular Testing: The valve resets automatically via spring force, achieving zero leakage with its spherical sealing surface. Wipe impurities off the sealing surface after reset. Conduct annual pressure tests to verify timely operation and reset, then apply anti-rust oil to the valve stem.
