Applications :
These are used as gastight closing valves of air ducts in Civil Defense and military shelters and industrial facilities. EEP gastight closing valves are primarily designed to separate contaminated and toxic-free spaces and to control the airflow between them.
Specification :
Manufacturer of gastight closing valve is European EMC Products, UK. It comprises a light metal alloy body with neoprene gaskets installed between two counter flanges. The closing part is an aluminum alloy or stainless steel flap installed within the body on a spindle with bearings. The flap can be locked in any position. All parts are effectively corrosion proofed: the valve body epoxy powder coated, the flap made of stainless steel or epoxy powder coated and other components galvanized.Gastight Shut Off Valve dimensions
Design Criteria :
The gastight closing valve complies with all known UK, NATO and international security and performance standards. The valve is designed to function within the operating temperature range of -20 …+55oC.
Leakage rate :
The leakage through the gastight closing valves does not exceed 5 x 10-4 l/s corresponding to a pressure differential of 1000 Pa across the valve. By pressurizing the void between the double flap of the KS-250-K valve with clean air, the leakage flow across the valve can be completely eliminated
These valves are available provided with electric, electric fail-safe and pneumatic actuators.
Typical Installations of valves Valves can be installed between ducts, into flanged wall sleeves, etc.
