The ZETRIX range has impressed the market for some time now with its durability, reliability, and high performance plus new types, sizes and pressure ratings now add even more to the flexibility of this superior range. A version with butt weld ends is now available, in addition to the double flanged and fully lugged designs. 

Hospitals all over the UK are benefiting from the added safety and efficiency that the ZETRIX valve can provide. With the advantages of a metallic sealing process valve combined with a butterfly design, these valves can be used for isolation and control. Boasting zero leakage and emissions, the triple offset principle guarantees a permanently tight seal, conforming to leakage rate A as per DIN EN 12266-1. That’s because the valve fits precisely and closes without friction. 

The ZETRIX can be set up as a double block and bleed isolation which can offer many benefits. They include improved health and safety standards, reduced downtime for maintenance repairs, and savings in energy and cost. HSE guidance suggests that double block and bleed is the only proved isolation in line with HSE Guidance 253 (Safe Isolation of Plant and Equipment). This states that double block and bleed is greatest in the hierarchy of mechanical security for isolation methods. 

This solution for isolation means that a section of plant can be isolated without having to shut down entire systems, as would need to be done with single isolation valves in place, allowing for easy and safe upgrade or maintenance work.

The small face-to-face dimensions of the ZETRIX provides even more versatility. If a customer wishes to change from single isolation to double isolation with bleed, only small changes to pipe work are required. A typical double block and bleed, which incorporates two ZETRIX, is the equivalent face-to-face dimension to most of isolation valves (typically gate and parallel slide valves). Therefore, the ZETRIX can be used for modifying pipe work with single isolation to double block and bleed to meet Health & Safety guidance with little alteration to the pipe work, ultimately saving time and money. 

ARI-Armaturen can make the spool piece fit any gap so the system can therefore be customised to specific installation restrictions. Currently, other ranges on the market seem to have a costly, limited choice compared to the comprehensive range of pressure classes, materials, and sizes available with the ZETRIX. The ARI solution can also be supplied with all forms of actuation (electric, pneumatic, etc) if required.
