Pressure Relief Valve Applications in Different Industries

1. Water Treatment Industry

Applications: Wastewater treatment plants, industrial water treatment, boiler feed systems.

Role: Prevents pipeline overpressure, protects metering pumps and system components, and ensures precise chemical dosing.

2. Chemical Industry

Applications: Acid and alkali transfer, corrosive liquid dosing, reaction vessel flow control.

Role: Maintains system stability when handling highly corrosive chemicals and prevents pressure-induced damage to pipes and equipment.

3. Oil & Gas Industry

Applications: Injection of corrosion inhibitors, defoamers, desulfurization and decarbonization systems.

Role: Ensures stable chemical injection under high-pressure conditions, preventing sudden pressure fluctuations that affect dosing accuracy.

4. Pharmaceutical & Biotechnology Industry

Applications: Liquid drug delivery, sterile water systems, laboratory precision metering pumps.

Role: Prevents pressure fluctuations that could impact formulation accuracy, ensuring stable and precise chemical dosing.

5. Food & Beverage Industry

Applications: Food additive dosing, syrup transfer, disinfectant injection systems.

Role: Maintains stable pressure during food-grade fluid transfer, ensuring accurate ingredient mixing and preventing overpressure issues.

6. Pulp & Paper Industry

Applications: Chemical additive dosing for paper pulp, coating agent transfer, ink supply systems.

Role: Regulates the uniform addition of chemicals, preventing product quality fluctuations due to unstable pressure.

7. Power & Energy Industry

Applications: Boiler water treatment, coolant dosing, coal-fired power plant desulfurization and denitrification systems.

Role: Prevents overpressure in high-temperature and high-pressure environments, prolonging the lifespan of metering pump systems.


Pressure relief valves play a critical role in different industries by regulating system pressure and protecting metering pump systems from overpressure damage. Choosing the right pressure relief valve based on industry requirements (material, pressure range, chemical resistance) is essential for ensuring system efficiency and longevity.
