UF4/UFR4 Pressure Relief Valve

The UF4/UFR4 Pressure Relief Valve offers enhanced performance, reliability, and ease of maintenance, making it an ideal choice for various industrial applications.

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​
• 3-A approved designs available / Designed to EHEDG guidelines​
• All product-contact parts are made of AISI 316L / DIN EN 1.4404 stainless steel.

Minimise Downtime​

• Enhanced control for improved response to pressure relief events (through proximity switches or through control unit feedback)​
• All valves come with a seal lifting function to open the valve during cleaning operation which helps minimize downtime​
• Clamps allow for a service friendly design ​

Optimise 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​
• The modulating cone of the UFR4 valve provides for slower, smoother closing of the valve when low flow is expected and prevent pressure hammers​
• Leverage the breadth of options to standardize your operations: can be supplied in nominal diameters from DN25 to DN100 and ISO 1" to 4"​

Feature:​

• 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. 
• UF4/UFR4 replacement insert fits into existing UF3/UFR3 housing making an easy upgrades to next generation with improved features. 
• Wide range of pressure settings can be achieved using four different actuators. 
• UF4 maintenance free actuator minimizes maintenance costs and downtime 
• The metal stop ensures defined compression of the seat seal, reducing material stress.  
• The UF4/UFR4 valves can be delivered with a comprehensive range of CU4, CU4plus control units.
