Cement - Double Flap Valves 

Clinker Coolers  
The use of Double Flap Gate Valves in the cement industry is well established. Some applications have found that the Double Flap Valve was the only solution which provided reliability and long life in an environment where temperature, abrasion and pressure are all factors. 
European Gate Valves offer proven operational reliability and improved maintenance performance through the facility to change wear components with the valves in situ. With a significant number of units providing for many years of service European Gate Valves ensures full support for its’ products and a spares service to meet the critical nature of the customer’s operation.

Alternative Fuel Kiln Feed Valves 
With the increasing reliance on alternative fuels for cement kiln operation European Gate Valves have supplied a number of valves to overcome the problems associated with these solid fuels. 
In the case of direct gravity feeding systems the valves also had to withstand the possibility of sustained high temperatures. With valves rated for up to 1,100°c the operators have felt confident that their upstream conveying systems are protected under all kiln operating conditions. 
Further protection was supplied in the form of emergency slam shut fire gates which, with their own air reservoirs, could isolate the kiln feed chute even if there was total power and mains air failure.

Maintenance Gate Valves 
Isolation of primary process equipment for maintenance purposes is often overlooked or considered an expensive luxury. European Gate Valves have worked with a number of companies to show the return on investment benefits through reduced downtime, improved Health and Safety environments and greater operational flexibility are real and tangible. 
With bespoke design and manufacture to suit the space constraints of existing equipment European Gate Valves can supply the solutions which will provide genuine returns.
