APV UFHP4 High-Pressure Relief Valve

Reliable Protection for Process Equipment

The APV UFHP4 High-Pressure Relief Valve, part of the UF Series, is expertly designed to protect pumps and process equipment from damaging pressure spikes, extending the capabilities of the UF4 line with relief pressures exceeding 10 bar compared to UF4's 0-10 bar range.

Integrated Monitoring and Cleanability

Featuring an integrated Control Unit for monitoring relief events and valve actuation during CIP cleaning, the UFHP4 ensures optimal process efficiency. Engineered to EHEDG guidelines, it maximizes cleaning cross-section for superior hygiene and reliability. Built with durable AISI 316L stainless steel, its ball-shaped valve body, maintenance-free actuator, and advanced feedback capabilities deliver robust performance while minimizing downtime and maintenance costs.

Key Benefits

Optimum Cleanability

• No dead spaces in the valve body
• No stroke limitation by seat lift actuator; the full opening cross section is available during cleaning
• Designed to EHEDG guidelines
• All product-contact parts are made of AISI 316L / DIN EN 1.4404 stainless steel.

Minimize Downtime

• Enhanced control for improved response to pressure relief events (through proximity switches or through control unit feedback)
• All valves features a seat lifting function to open the valve during CIP cleaning operation which helps in reducing downtime.

Optimize Your Process

• Protect your pump with an external over-pressure relief valve. If pump discharge pressure exceeds the set cracking-pressure, the valve will open to a relief path
• Leverage the breadth of options to standardize your operations: can be supplied in nominal diameters from DN25 to DN100 and ISO 1" to 4"

Engineering & Performance Highlights

• Ball shaped valve body with smooth passages, i.e., no sump and dome, making CIP-cleaning more efficient and more reliable.
• Seat lift actuator as a standard offering with feedback switches on top of the actuator.
• Wide range of pressure settings can be achieved using two different actuators.
• UFHP4 maintenance free actuator minimizes maintenance costs and downtime
• The metal stop ensures defined compression of the seat seal, reducing material stress.
• The UFHP4 valves can be delivered with a comprehensive range of CU4, CU4plus control units.
