Pressure Relief Valve with Remote Status Indicator - Reliable Safety
Remote Monitoring Pressure Relief Valve for oil-immersed power transformers
This product is an intelligent valve integrating pressure protection and remote signal transmission, specifically designed for oil-immersed electrical equipment such as transformers and power capacitors. It rapidly releases excess pressure during abnormal internal pressure conditions while transmitting real-time electrical signals for remote alarm or control system activation, enabling continuous monitoring and smart management of equipment safety.
Product Paramenters
* Spray Port Options: Available in effective diameters of φ50, φ80, and φ130.
* Universal Mounting Flange: Compatible with existing installations, allowing direct replacement of conventional pressure relief valves.
* High Protection Rating: IP65-rated enclosure for dust and water resistance.
* Adjustable Oil Guide Flange:
* Constructed of stainless steel for durability.
* Supports telescopic adjustment of installation distance, free left/right swiveling, and 360° rotation for flexible and efficient installation.
* Dual-Layer Gasket Design:
