Check valves with hydraulic brake
In cooperation with Konrad GmBh. we supply double eccentric check valves with hydraulic brake system for cooling water, seawater, coke gas and other demanding conditions. Konrad's patented Exentromat® check valves feature a double eccentric valve blade and a welded body made of forged steel or stainless steel. Because of this high-quality design, Konrad valves can be seen as rock-solid valves that achieve very long service lives. The braking system can be designed as desired to set the ideal closing time.
The Konrad check valve with hydraulic brake is available as a check valve or as a combined check valve/butterfly valve and is 100% gas tight -two-sided if desired. Through worm gearbox, the valve can be locked in open or closed position in case of calamities or maintenance. Because each individual component can be manufactured from multiple materials, this valve is perfectly adaptable to different circumstances.

Application
The robust design and double eccentric seal make this valve suitable for the most severe conditions. For this reason, this valve is often used for shutting off cooling water, seawater, coke gas, steam and other mediums that require a long stand time without maintenance. The version with hydraulic brake is recommended for any application where fast closure is undesirable to prevent water hammer.
