Bulk Materials - Feed and Discharge Valves 
 

Kiln Feed Valves 
 
When a leading soda ash manufacturer decided to automate its kiln feeding system it turned to European Gate Valves for a valve to satisfy the unique and challenging operating conditions. 
 
The new system required a valve capable of receiving a 3 tonne charge of up to 100mm rocks from a height of 3 metres, holding this charge above the kiln, releasing it in less than 0.5 seconds to ensure a parallel drop onto the dispersion cone and then closing again as quickly to minimise the escape of carbon dioxide. This cycle was to be repeated every 3 minutes. 
 
The valve had to be tough enough for the duty and able to operate 365 days per year with at least 2 years between shutdowns. Initially life expectancy of the unit was 10 years though with experience this has been revised to 20 years. 
 
The valve is designed so that all components can be removed without taking the body of the valve out of line. This philosophy is used on most of European Gate Valves products. 
 
This customer is not unique in its search for a suitable UK manufactured heavy duty valve where the manufacturer has the flexibility, experience and resource to respond to special conditions seen by thermal processes.

Silo Discharge Valves 
Light Duty 
 
Total product shut off when discharging from hoppers, bins and silos is an important process requirement. Whether for flow control or equipment isolation the need for reliable, maintainable valves is one which European Gate Valves addresses with a wide range of valve configurations and drives. For light powders and free flowing products European Gate Valves produce a range of slide gate valves which are cost effective whilst being robust enough to give long trouble free life. 
 
Heavy Duty 
 
For heavy duty applications as defined by the presence of either high loads, abrasive products, high temperatures or standing columns of dense material European Gate Valves valves again meet the challenge. A range of valves utilising double rack and pinion drives where the drive is out of the material flow have been utilised. As with nearly all European Gate Valves products the valves have been developed with ease of maintenance in mind and provide for full replacement of internals without removing the valve body from the line.
