SCHROEDER SHP – A VALVE FOR HIGH PRESSURES AND ALL LOAD CONDITIONS

Schroeder Valves presented their latest innovation at ACHEMA: the Schroeder High Pressure Valve SHP. This automatic re-circulation valve was developed for high and extremely high pressures and also works reliably under highly fluctuating load conditions and long periods of operation under partial load conditions. This is achieved using a special fully automatic minimum flow control system that ensures that flow never falls below the required minimum specified by the pump. With this innovation, t…

Arca Series 190 – Forged Steel for your Safety

ARCA Regler completes the product range of control and shut-off valves for the steam turbine periphery and other applications with the new 190 series. Especially designed to meet high pressure and extreme temperature demands. Due to the rapidly increasing technology requirements especially in power plants with higher steam or condensate temperatures as well as an increasing number of regular temperature changes, valves in such service normally suffer high stress. Inappropriate design or incorrec…

Richter KNR 200

Richter, a leader in PFA lined pump and valve solutions, is introducing a new size control ball for its KNR and KNAR control ball valve series. Increasing production quantities require larger diameters of pipelines and thus also larger valves. In today’s world-scale plants, everything is optimised to the maximum possible capacity for best economic results. Richer anticipated these changing requirements with the launch of the world’s largest PFA-lined control ball for the KNR/F DN200and the K…

ARCA – 6H Rotary Gate Valve

ARCA – 6H Rotary Gate Control Valve A New Approach for a Severe-Duty Microflow Valve ARCA 6H Rotary Gate Control valves are used in a wide range of capacity, from butterfly valves with a rated flow coefficient Kvs of more than 50.000 m³/h (enough capacity to fill an Olympic swimming pool within 3 minutes) down to microflow valves with less than 10-5 m³/h rated flow capacity. Such a microflow valve would need more than 20 hours to fill a glass of water. Microflow Control Valves Typically…

Zwick Triple Offset Sealed Bearings Eliminate Common Failures

1. The Problem Bearing failures are among the highest root causes of failure in triple offset valves (TOV) for tight shutoff applications. This issue is directly attributed to the need to have metal bearings with very tight tolerances when accepting the shaft diameter. Properly designed triple offset valves are metal to metal torque seated type valves. Therefore, very little shaft deflection can be tolerated in order to torque the seal ring into the seat. Additionally, properly designed TOV’s …
