Efficiency, Innovation and
Reliability assured

At Unison, we understand that engineering and technologies are continually evolving in manufacturing environments and brands like Evoguard need to react to this changing landscape. In that context, Evoguard deploys innovative technology for valves, valve manifolds and Vessel Dome Fittings used in process and filling technology. Our valves perfectly illustrate first-class KRONES quality at component level.

Manufactured in accordance with the highest quality and hygienic design guidelines, Evoguard is a proven, market-leading brand. Demonstrating high efficiency standards, they also maintain a focus on easy and reliable operation in everyday production. The Evoguard range of cost-effective, modular valves has been developed with busy manufacturing environments in mind.

Highest quality manufacturing process

Evoguard Manufacture the valve housings with chipping solid stainless steel material and ensure accurate traceability and identification of parts by matrix code. Tested materials are also used with acceptance test certifications.

Energy savings included

With actuator variants in modular concept and adjusted to systems with a product pressure of 6, 10 or 22.7 bar, energy efficiency is a high priority. Economical control air consumption is deployed for double seat mixproof valves with fast stroke movements for cleaning the leakage space.

Process Safety

Evoguard valves are designed with optimised sealing geometry, certified by the EHEDG while seal installation areas are designed to facilitate hygienic production conditions.

Consistent when it comes to safety demands

Designed according to the requirements of European Machinery Directive 2006/42/EC and Pressure Equipment Directive 2014/68/EU, they have also passed design review by TÜV SÜD technical inspection authority (pressure, safety, strength testing, etc.)

Safe handling during daily production activities

Evoguard valves are easy to assemble and disassemble without special tools while actuators in welded design are maintenance-free. You cab also benefit from safe and quick spare parts replacement without risk of accident or confusion of seals.


In a time of rising material and energy prices, we understand the importance of supplying cost-effective equipment solutions, ensuring costs are controlled where possible.
