Large Pressure Relief Valve
Mechanical device for rapid relief of excessive pressure in large volumes of gas or liquid.
Equipped with a patented dual-sealing system that ensures immediate response to overpressure and automatic tight closure once pressure returns to normal. Additional options include local operation indication, built-in contacts for activation signaling, and a discharge shield for the safe diversion of hot oil and gases.
Features
- World-leading pressure relief device that first introduced automatic resealing
- Robust design and materials ensure consistent protection and long service life
- Dual-sealing system creates enhanced pressure, enabling fast and reliable valve operation
- Patented secondary sealing gasket provides superior sealing reliability
- Operating valve, mounting hardware, and components are made of stainless steel
- Flange and ring are made of aluminum with chromate conversion coating, and visible aluminum components feature an additional epoxy coating
- Switches can be configured as latching or momentary (SPDT or DPDT types), supporting high DC or low current, with gold contacts and connection options via plug, terminal box, or cable connection
- Universal mounting: horizontal top installation (recommended) or vertical side installation
- 100% factory-tested to ensure quality
- Test results feature unique serial numbering for full traceability and quality control
- Visual and remote indication of valve operation
- Standard units support up to two alarm switches, which can be mounted directly on the device or on the discharge shield
Options
- Operating pressure, sealing material and type, housing material, indicator type and color
- Up to two latching or momentary switches (single-pole or double-pole Form C, high DC or low current with gold contacts)
- Type of electrical connection
- Gas release system
- Optional discharge shield can be connected to a pipeline, providing maximum protection for equipment, personnel, and the environment by redirecting the flow of hot oil and gases
- Optional semaphore (flag) for visual activation indication, available in various colors and materials
- Main housing available in zinc-coated steel or stainless steel for enhanced strength and corrosion resistance
Applications
Designed for overpressure protection in oil-filled transformers, on-load tap changers, and other electrical equipment. It can be integrated into intelligent transformer monitoring systems to enhance automation and safety levels.
