Electromagnetic pressure relief valve

Valv Technologies (VTI), a U.S.-based company, was founded in 1987 and is headquartered in Houston, Texas.

Core Position: A global leader in designing and manufacturing metal valve seats, zero-leakage solutions, and valves for extreme operating conditions, and the world's largest integrated manufacturer of metal-seat ball valves.

Core advantage: Featuring the 'zero-leakage under extreme conditions' technology, the product withstands extreme environments including high temperatures (up to 982°C), high pressure (up to 138MPa), ultra-low temperatures, and high particulate wear.

The main products include metal-seat ball valves, electromagnetic pressure relief valves, and isolation valves, with the latter being widely used in thermal power plants.

Certification: The product has obtained authoritative international certifications including API, ANSI, and IBR, meeting stringent safety standards for nuclear and thermal power applications.

Industry applications and partner clients

Key industries: thermal power, nuclear power, oil and gas extraction, mining, papermaking, etc.

Key applications include boiler/turbine drain systems, main steam isolation, and safety relief systems, where electromagnetic pressure relief valves are the standard configuration for units of 300MW and above.

The electromagnetic pressure relief valve features a compact design, with the main body constructed from forged alloy steel and coated with high-temperature corrosion-resistant material. Key specifications: The valve incorporates an integrated electronic actuator at the top, equipped with a pressure sensor and control module, along with flange connection interfaces on the side.

When the pressure in equipment such as boilers or pressure vessels exceeds the specified value, excessive pressure may lead to catastrophic failures. Therefore, pressure relief devices are referred to as the "last line of defense" for pressure-bearing equipment.

The standard parameters for electromagnetic pressure relief valves in 300MW thermal power plants are:

Pneumatic ball valve Model: 2.5×4 E0L121N7BWRA5P1

Set pressure: 18.11MPa; return seat pressure differential: 2%; connection method: butt welding;

Isolation Valve Specifications: 2.5×2.5 B0L1-21-ISO-BW2.5

The electronic safety valve (ERV) is designed with safety ratings, productivity values, and cost efficiency in mind, featuring standard discharge and set pressures with an accuracy of 0.1% of 1 psi. ValvTechnologies 'ERV combines a zero-leakage isolation valve with electronic control for monitoring and regulating system pressure in safety valve environments, meeting the ASME Section 1' V 'Seal requirement where critical overpressure protection is essential. ValvTechnologies' ERV serves as the industry benchmark.
