INOXPA 74700 Overflow Valve

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.

Specification

• 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
