Valve seriesfor the beverage and food industryand for aseptic processes

Who is Evoguard?

EVOGUARD is a specialist for components: Our comprehensive valve programme offers the appropriate solution for all process technology tasks. All valves meet the highest safety standards and work absolutely reliably in continuous operation.

The excellent functionality of our valves is based on the fact that we have implemented all demands for hygienic design in our completely re-engi-neered modular valve system. Moreover, we are using modern configura-tion and representation methods to design our valves and optimise their performance. Not least, our manufacturing department with its modern machining centres provides ideal conditions to guarantee the high qual-ity of our valves.

Valves are the basis for a safe, automated process.EVOGUARD valves and components.

Why EVOGUARD?

TYPE EL - CLASS IJANUARY 2011

Highest quality in the manufacturing process ■ Manufacturing of the valve housings by chipping solid stainless steel

material ■ Accurate traceability and identification of parts by means of Matrix Code ■ Use of tested materials with acceptance test certifications

Process safety ■ Optimised sealing geometry, certified by the EHEDG ■ Housings without dead space and optimally designed installation

areas for the sealing for hygienic production conditions ■ Sealing materials according to the specifications of FDA 21 CFR regula-

tion and the EU decree no. 1935/2004

Energy savings included ■ Actuator variants in modular concept, adapted to systems with

a product pressure of 6 bar, 10 bar and 22.7 bar ■ Low control air consumption for double seat mixproof valves with fast

lifting movements for leakage chamber cleaning ■ Free cross-sectional areas in relation to the pipe diameter

Safe handling during daily operation ■ Easy assembly and disassembly without special tools ■ Maintenance-free actuators in welded design ■ Safe and quick spare parts replacement without risk of accident

and confusion of seals

Consequence when it comes to safety demands ■ Design according to the requirements of EU Machinery Directive

2006/42/EG and Pressure Equipment Directive 2014/68/EU ■ Design inspected by the Technical Inspection Agency TÜV Süd (pressure

test, safety test, strength test, etc.) ■ Pressure-resistant design of the housings of seat valves for PN 25

pressure rating

Valves for shutting off pipe systems

Seat valvesTo particularly suit the process conditions

■ Valve disk with balancer: – Reduces pressure surges when closing in the direction of flow – The cone-shaped valve disk ensures a gentle transfer of the product

■ Metal stop for the valve disk to protect the seal ■ Two-piece threaded valve disk with

– Defined space for the sealing ring – Easy assembly without risk of twisting – Seal resistant to seepage and rip-out

■ Design of the shaft seal: – Wiping function protects against contamination ingress – Geometry protects the seal against being torn out

■ High product pressure of up to 22.7 bar ■ Avoidance of pressure surges when closing

Hygienic valves

Butterfly valvesInexpensive shut-off fitting for product and CIP

■ Solidly designed valve disk ■ Safe guidance of the disk thanks to bushes in the housing ■ Seal with a small volume and extension gaps for compensating tem-

perature expansion ■ Seal flush against the housing, bevelled seat ensures that the disk

opens and closes securely with minimal wear ■ Reliable sealing over the entire temperature range ■ Innovative seal design and composition of the elastomer according to

the latest research findings ■ Easy installation with different connection variants

ESL membrane technology

Seat valvesFor sensitive beverages without preservatives and beverages distributed outside of the cold chain

■ Cost-attractive design, suitable for ESL applications ■ Rotational decoupling on linkage between valve shaft and actuator

for torsion-free lift motion of the valve disk ■ Suitable for all products and cleaning agents

(sealant material: PTFE compound) ■ Optimum cleaning conditions ■ Free cross-sectional areas in relation to the pipe diameter ■ Designed for up to 500,000 switching cycles

Aseptic metal bellows

Seat valvesFor aseptic and sterile processes

■ Hermetic separation of the valve interior by means of metal bellows ■ Bellows with supporting element for:

– Reducing vibrations in the process – Increasing the lifetime of the bellows

■ Two-piece screwed-on valve disk optionally available: – Sealant material: EPDM/FKM/HNBR – Defined space for the sealing ring – Easy assembly without risk of twisting – Seal resistant to seepage and rip-out

■ One-piece valve disk with sealing ring (PTFE compound) optionally available ■ Connections for leakage drain/bellows monitoring ■ Rotational decoupling on linkage between valve shaft and actuator for

torsion-free lift motion of the valve disk ■ Housing design for optimum cleaning and gentle product transfer

Hygienic valves

Double seal valvesSeparation of media such as CIP, water or gasses

■ Economical alternative to double seat mixproof valves ■ Valve disk with two seals between the pipe systems when in

a closed position ■ Leakage chamber equipped with two rinsing valves for leakage display ■ Cleaning with a tangential rinsing-medium inflow ■ Avoidance of dead space thanks to the hygienic sealing of the rinsing

valves directly at the product area ■ Design of the shaft seal and seal on the valve disk similar to the

seat valve

Double seat mixproof valvesPressure-resistant separation

■ Two valve disks working independently from one another, used for sealing between the pipe systems when in a closed position:

– Leakage-free switching – Resistant to pressure blows up to min. 45 bar – Liftable and rinsable design for cleaning the leakage chamber

■ Screwed-on valve disk: – Defined space for the sealing rings – Easy assembly – Seal resistant to seepage and rip-out

■ Universally applicable seal for radial and axial sealing ■ Design of the shaft seals similar to that of the seat valve ■ The valve disks are sealed together directly in the product room

and without a gap in between ■ Actuator with integrated cycle function for fast cycle times and

low air consumption MLDouble seat
