FOX DR Series Rupture Disc
The FOX DR Series Rupture Disc represents an outstanding engineering solution for the safety of hydraulic systems. This technical component is specifically designed to safeguard the integrity of the accumulator, preventing structural damage in the event of abnormal system operating conditions.
Operating Principle and Safety
The operation of the FOX DR Series Rupture Disc is based on an instantaneous mechanical response to critical variations in system parameters. Its primary function is to intervene safely and permanently in the event of overpressure or overtemperature conditions. When one of these limit conditions occurs, the valve structurally fails in a controlled manner, releasing the nitrogen contained inside the accumulator. This immediate depressurization isolates the hazard, protecting the accumulator body from the risk of explosion and ensuring the safety of both the system and operators. The rupture point accuracy is guaranteed with a tight tolerance of ±10%.
Construction Features and Materials
The strength and reliability of the FOX DR Series Rupture Disc derive from the exclusive use of high-quality stainless steels, capable of withstanding severe industrial environments. The entire functional assembly is homogeneous in terms of materials to avoid galvanic reactions and ensure perfect sealing. Material specifications include:
-
Body material: ASTM A240 316L.
-
Disc material: ASTM A240 316L.
-
Seal material: ASTM A240 316L.
The component design also allows engineers to choose the discharge orientation, which can be radial or frontal, depending on the available space and the architecture of the hydraulic system.
Hydraulic Connections and Operating Parameters
Installation flexibility is a key feature of the FOX DR Series Rupture Disc. The standard hydraulic connections supplied are 1/4″ NPT-M and 1/2″ NPT-M, covering most traditional system requirements. However, special hydraulic connections can also be requested and manufactured according to drawings or specific technical requirements. Unlike standard valves, the operating limits of this component are fully customizable: rupture pressure and rupture temperature are defined and calibrated strictly according to customer requirements.
Regulatory Compliance
As a primary safety device for pressure equipment, the FOX DR Series Rupture Disc has been designed and tested to meet the strictest European directives. The component is fully compliant with CE/PED regulations, guaranteeing the highest legal and quality standards for integration into modern industrial hydraulic systems.
