Varem's Dual-Acting Rupture Disc: A Smart Safety Solution for Industries

Posted on: July-11-2025

Varem's dual-acting rupture disc is a game-changer for process industry safety. It provides robust, two-way protection, fast delivery, and streamlined installation.

Many industries, like petrochemicals, pharmaceuticals, and food processing, need to protect their equipment from overpressure and vacuum conditions. Traditionally, this required two separate safety devices or custom-made solutions. But now, there's a simpler and smarter way.

The Problem

Industrial systems need to operate safely under both positive and negative pressures. Until now, many plants used two separate solutions, which added complexity, installation time, and spare part management.

Varem's Solution

Varem developed a dual-acting rupture disc that protects against both overpressure and vacuum conditions in just one device. This innovative solution was developed in just five weeks.

Key Features:

• 1. Two-way Protection:
  • One device protects against both pressure extremes.
• 2. Forward-Loaded Design:
  • Ruptures cleanly and minimizes fragmentation.
• 3. High Operating Thresholds:
  • Operates at up to 60% of burst pressure (positive) and 50% (vacuum).
• 4. Suitable for Liquids and Gases:
  • Works in various process industry applications.

Benefits:

• 1. Simplified Installation: One device reduces complexity and engineering time.
• 2. Increased Reliability: Fewer parts mean fewer failure points and easier maintenance.
• 3. Faster Delivery: Delivered ready-to-use in weeks, not months.
• 4. Versatile Application: Effective in multiple processing environments.
