Description
A stainless steel ball valve is a reliable and versatile device for controlling the flow of liquids and gases in various industrial sectors. Made from corrosion-resistant stainless steel, it possesses high strength and can withstand both high temperatures and pressures. Ball valves are easy to operate, provide secure sealing, and minimize the risk of leaks, making them an ideal choice for use in the oil and gas industry, water treatment plants, the food industry, and other areas where a reliable and durable valve is needed to regulate the flow of substances.
Double-acting pneumatic rotary actuators and pneumatic rotary actuators with return springs are designed for automation of control process of 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 actuators are used for control in pneumatic systems having NAMUR docking surface, for installation of actuators through through holes in the body.
The DNOVA HDM Disengageable Clutch Manual Doubler allows manual adjustment of the required positioning of valves, dampers and other quarter-turn devices when replacing pneumatic, electric or hydraulic quarter-turn actuators. Suitable for both indoor and outdoor installation. The modular design of the manual override is designed to provide the most efficient and effective solution to the full range of manual override applications.
The AFC2000 DNOVA air treatment unit is designed to clean compressed air from moisture and solid particles, remove condensate, automatically maintain the pressure at a preset level, supply lubricant from a reservoir in the compressed air flow to the pneumatic system elements with a large capacity range from 500 litres/minute to 10,000 litres/minute. The lubricator (oil atomiser) adds oil with a viscosity of 32 mm²/s (=cSt) at 40°C to the pneumatic system for further lubrication of control components - pneumatic cylinders and pneumatic valves.
