Description
Butterfly valves DNOVA al-316l-epdm are designed for use as shut-off or regulating valves for flow control in heat and water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries. Butterfly valves should be installed only between collar flanges.
Pneumatic double-acting rotary actuators and pneumatic rotary actuators with return springs are designed to automate the process of controlling industrial shut-off valves - gates, ball valves. DNOVA pneumatic actuators are designed for operation both indoors and outdoors. All internal and external parts are anticorrosive coated.
Pneumatic valves are used for control in pneumatic systems with NAMUR docking surface, to install the valves through holes in the housing.
