Product Description
Product Details
Designed for oil-immersed power transformers and reactors, the valve is installed on the transformer tank wall. When internal pressure exceeds the set value due to fault, it opens instantly to release pressure; after pressure recovery, it automatically resets and seals tightly to prevent oil leakage and moisture intrusion. Optional signal output realizes remote monitoring and fault alarm, meeting the safety requirements of power distribution and power transmission projects.
Product Features
1. Fast pressure relief: High-sensitivity sensing structure, rapid response to overpressure, efficient pressure release
2. Precise control: Stable opening/closing pressure, no misoperation, long-term performance consistency
3. Reliable sealing: High-grade sealing material, oil-resistant and aging-resistant, zero leakage in normal operation
4. Auto reset: Automatic reset after pressure relief, maintenance-free, easy installation
5. Signal output: Optional electrical signal contact, supporting remote monitoring and intelligent management
