The overflow valve is a crucial safety component used to perform pressure bypasses in various systems, ensuring the protection of lines, pumps, accessories, storage tanks, and other essential equipment. By effectively managing excess pressure, the overflow valve plays a vital role in preventing potential damage and ensuring the safe operation of industrial processes. Its primary function is to provide a controlled outlet for excess fluid, thereby safeguarding against pressure surges that could lead to catastrophic failures or unsafe conditions within the facility.

Designed with safety as a top priority, the overflow valve features a sanitary design that minimizes the risk of contamination, making it particularly suitable for applications in sensitive environments. This thoughtful design helps to uphold the integrity of the process, especially in industries where hygiene is paramount. The valve is fully manufactured from high-quality stainless steel, ensuring durability, corrosion resistance, and compliance with stringent hygiene standards. This robust construction not only enhances the valve’s longevity but also makes it easy to clean and maintain, further contributing to its reliability in demanding applications.

The 74700 valve, specifically, is regarded as the most suitable option for protecting facilities in the dairies, food, beverages, pharmaceuticals, and fine chemicals industries. Its sanitary design ensures that it meets the strict regulatory requirements for cleanliness and safety in these sectors, making it a trusted choice for operators who prioritize product integrity and system reliability. With its ability to mitigate risks associated with pressure surges and its adaptability to various applications, the overflow valve stands as an indispensable element in modern industrial operations, providing peace of mind to facility managers and operators.

• Normally closed valve.
• Easy manual adjustment.
• Under normal operating conditions, the valve remains closed.
• The valve is calibrated to a specific pressure by regulating the spring with the pressure nut.The calibrated pressure is a Max. safety pressure defined to avoid damage of the plant.
• When the pressure in the circuit exceeds the calibrated pressure, the valve opens letting the flow pass and reducing the pressure of the pipe system.
• The valve can incorporate a handle designed to partially open the valve. When the handleis kept in the open position during the CIP process, the cleaning products can pass through the valve.

Materials

• Parts in contact with the product: 1.4404 (AISI 316L).
• Other stainless steel parts: 1.4307 (AISI 304L).
• Gaskets: EPDM.

Options

• Seat seals in FPM and PTFE .
• Several operating ranges by changing the spring.
• The assembly of the handle allows to partially open the valve in order to allow the passage of fluid for CIP cleaning (for use with positive displacement pump bypass).
• Safety seal to identify the factory calibration.
