Shut-off Gastight Valves for Shelters and Industrial Applications
GK gastight valves with double eccentric axle design, are airflow regulation valves designed for installation on the air ducts of ventilation systems of shelters and protective structures. The valves are commonly used as shut-off devices to stop or control the airflow and protect the inner space. The special design allow high pressure loads and long-life of the valve with minimal maintenance.
Advantages of Atmas Shut-off Gastigh Valves
-
GK gastight shut-off valves have special design with double eccentric axle.
-
GK valves can be delivered with manual and motorized drive.
-
The valves are designed to hold a high static pressure loads and can be used in ventilation systems of shelters and protected facilities.
-
The valves have a welded steel body or optionally can be made from stainless steel for very corrosive environments.
-
The valve can be installed at any direction on the air duct.
-
Minimal effort to operate the valve;
-
When opening / closing, there is no friction of the sealing ring on the seat;
-
Long service life of the sealing elements;
-
Replacing the seal is a simple procedure that does not require special tools;
-
Continuous sealing surface (360 degrees) provides the highest class of tightness.
