Pressure Relief Valves

Pressure Relief Valves

Our Pressure Relief Valves (PRVs) are precision-engineered borosilicate glass safety valves designed to automatically release excess pressure from reactors, vessels, and closed process systems. These valves play a critical role in protecting glass reactors, pipelines, and process equipment from over-pressure conditions, ensuring safe, controlled, and uninterrupted operations in chemical, pharmaceutical, and laboratory environments.

Manufactured from Borosilicate Glass 3.3, our pressure relief valves offer excellent chemical resistance, thermal stability, and visual flow monitoring, making them ideal for corrosive, high-purity, and pressure-sensitive applications.

How Pressure Relief Valves Work – Step-by-Step Process

1. Normal Operation – Valve remains closed under standard operating pressure
2. Pressure Build-Up – Internal system pressure increases beyond safe limits
3. Set Pressure Activation – Valve opens automatically at the preset pressure
4. Pressure Release – Excess gas or vapor is safely vented
5. Pressure Stabilization – System pressure returns to safe operating range
6. Automatic Reset – Valve reseats once pressure normalizes

• Fully automatic safety mechanism
• No external power required
• ontinuous system protection
