DESIGN PARAMETERS

Arflu Plug valves are designed to resist efforts as severe as process water treatment by reverse osmosis process. For this, Arflu Engineering Department has developed a valve which design is based on traditional analytical calculation and using international standards ANSI B16.34 and UNE EN 12516.

We use the latest technology (3D Design and Finite Element Analysis) to optimize the design, comparing stresses and strains, calculate allowable flow in the valve and the pressure distribution in the reduction step to avoid turbulence and cavitation.

We have improve service and reliability of our product and we have also reduced to the lowest possible maintenance costs. One example is the Q-Ch System or “Quick Change Sleeve” for a simple, quick and economical replacement of PTFE / Teflon sleeves. (*) See Doc. Download Q-Ch in “TECHNICAL DATA”.

Arflu Plug valves are made of stainless materials, Duplex and Super Duplex according to requirement of our customers and are usually installed in the High Pressure lines or final process of Reverse Osmosis.

We have designed our Plug valves 3 core services within Reverse Osmosis:

1. CIP / Cleaning Membranes. (*) See Doc. Download CIP Sketch in “TECHNICAL DATA”.

2. Isolation Valves or ON / OFF Service.

3. Regulating Valves for Pump High Pressure Discharge.
