SS304 Sanitary Adjustable Pressure Relief Valve (1.5" - 2" Tri-Clamp, 0.3-2.5 Bar)

Technical Specifications

Why must this adjustable pressure relief valve be installed vertically?

• Gravity and Spring Alignment

• Due to the internal mechanical structure of the PRV, installing it perfectly vertical ensures that gravity acts evenly on the internal spring and sealing disc. If installed horizontally or at an angle, the internal components can experience uneven friction and wear. Vertical installation guarantees that the valve will pop off exactly at your set pressure (e.g., 1.5 Bar) and reseat uniformly, preventing premature leakage or pressure inaccuracies.

How is an adjustable PRV used in beer brewing and fermentation?

1. Spunding / Natural Carbonation: Brewers use this adjustable valve on fermenters to trap naturally produced CO2 toward the end of fermentation. By setting it to a specific pressure (e.g., 1 Bar), excess gas vents out, while the exact amount needed to perfectly carbonate the beer remains inside.

2. Tank Safety: It acts as a primary safety mechanism, ensuring that if a regulator fails or fermentation is more vigorous than expected, the stainless steel tank will not exceed its maximum pressure rating and rupture.

Adjustable Pressure Relief Valve (Sanitary Safety Valve): Application and Use Cases

Adjustable pressure relief valves, particularly in sanitary applications, are designed to protect equipment and systems from excessive pressure, ensuring operational safety and system reliability. These valves are widely used in industries where hygiene, cleanliness, and precision control are critical.

Key Applications

1. Food and Beverage Industry

• Breweries and Distilleries:

• Maintain consistent pressure in brewing tanks and fermenters.

• Prevent over-pressurization during carbonation and fermentation processes.

• Dairy Processing:

• Protect milk pasteurization equipment from pressure surges.

• Maintain hygiene and ensure no contamination during pressure adjustments.

• Bottling Plants:

• Control pressure in filling lines to avoid overflows or bottle bursts.

2. Pharmaceutical Industry

• Sterile Production Lines:

• Ensure pressure control in bioreactors and fermentation tanks.

• Maintain sterile environments by preventing backflow or leaks.

• API Manufacturing:

• Protect against excessive pressure in reactors and filtration units.

3. Cosmetics and Personal Care

• Cream and Lotion Production:

• Control pressure in mixing tanks and homogenizers.

• Perfume Manufacturing:

• Prevent over-pressurization in volatile liquid storage or transport lines.

4. Water Treatment Systems

• Reverse Osmosis (RO) Systems:

• Release pressure build-up in filter and membrane units.

• Sanitary Filter Protection:

• Prevent damage to sensitive filters from sudden pressure surges.

Features Beneficial to Sanitary Applications

1. Adjustability: Allows precise pressure setting based on the system's operational needs.

2. Hygienic Design: Typically made of stainless steel (e.g., SS304, SS316L) with smooth, polished surfaces to prevent contamination and bacterial growth.

3. Ease of Cleaning: Compatible with CIP (Clean-in-Place) systems, ensuring seamless cleaning without disassembly.

4. Compliance: Adheres to strict sanitary standards (e.g., 3-A, FDA, EHEDG).

5. Durability: Resistant to corrosion and chemicals used in cleaning or production processes.

Why Choose a Sanitary Adjustable Pressure Relief Valve?

Sanitary valves are specifically designed for environments where maintaining cleanliness and sterility is crucial, ensuring both safety and compliance with industry regulations. The adjustable feature makes them versatile, capable of adapting to different system pressures as needed.
