25 Tons Goggle Valve for India
An environment-friendly goggle valve DN 1800 was manufactured in the production plant of ARMATURY Group a.s. in Dolní Benešov.
This goggle valve, weighing 25 tons is intended for a metallurgical plant in India.
The production stages and assembly took place according to a pre-planned schedule, followed by successful acceptance by the customer, painting to the required colour, thorough overseas packing and then transport to the port in Hamburg. From there the goggle valve will be transported to India by ship. This seemingly simple process involves a series of operations that result in a perfect ecological product made up of thousands of parts.
The use of a goggle valve
The goggle valve is used as a safety stop valve in gas pipelines for transporting blast furnace, converter, coke oven or mixed gas. The environment-friendly goggle valve consists of a closed body, two side covers, a frame with flow and shut-off plates, a hydraulic motor system with plate release accessories, an actuator to reposition the frame with the plates, and many other parts.
In the closed position this valve must 100 % prevent the penetration of toxic gases into the enclosed part of the pipe for maintenance, repair or inspection. The environment-friendly (closed) design of the valve has the advantage over the open design in that no gas leaks into the surrounding environment during the repositioning phase of the frame and plates (opening/closing of the valve) and the gas remains in the body and covers. This prevents contamination of the surrounding environment.
