Aseptic Pressure Relief Single Seat Valves

Aseptic Pressure Relief Single Seat Valves - UFMS4

The UFMS4 valve is an Aseptic Pressure Relief Valve, used to protect pumps and related equipment from pressure spikes downstream. It can relieve pressure from 0-10 bar and includes controls for monitoring pressure relief events and actuating the valve during clean in place. Vital for maintaining aseptic conditions and ensuring product quality and safety in processes where sterility is paramount and pressure relief is necessary.

UFMS4 Aseptic Pressure Relief Valve

Ensuring Sterile System Integrity

The UFMS4 aseptic pressure relief valve is essential for maintaining system sterility, particularly in environments where contamination poses significant risks. It is crucial in processes requiring a sterile environment, preventing contamination while relieving excess pressure.

Key Benefits

Optimum Cleanability

No limitation on stroke due to seat lift actuator; full opening cross-section is available during cleaning
3-A approved and designed to EHEDG guidelines for hygienic operation

Minimize Operational Downtime

Enhance control for improved response to pressure relief events; facilitated by proximity switches or control unit feedback
All valves feature a seat lifting function to open the valve during cleaning operation reducing downtime

Optimize Process Efficiency

Protects pumps with an external over pressure relief valve. If the pump discharge pressure exceeds the preset cracking pressure, the valve will open to provide a relief path.
Choose from a range of options to standardize operations, available in nominal diameters from DN25 to DN100 and ISO 1” to 4

Housing / Body Configurations:

A comprehensive range of valve housings and body configurations are available to accommodate various requests.

Control Units:

The APV UFMS4 valves can be equipped with a wide array of CU4 and CU4plus control units. These units are electrically designed for direct connection (DC) to a PLC system (CU4, CU4plus Direct Connect) and to fieldbus protocols like AS-i. Additionally, CU4plus also supports fieldbus protocols such as IO-Link.

Proximity Switches:

Proximity switches detect valve full open or close conditions during any necessary CIP cleaning.
