    COVNA CV-E11 dc24v high temperature electric entilation valve/actuators                 Media: air, oil, steam, fluid, corrosive liquid, fuel etc. Medium Temperature: -20°C~300°C Fluid pressure: 0.1~0.6Mpa Material: stainless steel Port size: 2″~12" Orifice: DN50~300 Valve seat material: PTFE Please mark clearly the fluid when you are ordering if the fluid is very special  ( e.g. steam, gas, vacuum, diesel oil, heavy oil). Company Information         COVNA Automation Industry Co. Ltd. was founded in 1999, specializing in the   productions of Solenoid Valve and Pneumatic Valve on pipeline fluid. COVNA,   original brand, runs its business around the world and its quality awards ratification   through competing with European countries, the United State, Japan and Other major   industrial countries in the international market.       By far, export production ranks first in the country with its sale throughout the   country in the field of two position Two Way Solenoid Valve. Since the general manager   has enter into the industry of valve, pipeline fluid automation and labor saving, he has   hold the Three First business philosophies those are quality coming first, service first,   and credit first all the time. It makes the quality and output of our products advance   at an equal pace with the products’ quality and output from Europe, the United State   and Japan in the international market. With its reasonable price, even the medical device   industry in France, Spain and other countries install our products, COVNA solenoid   valves, in their medical devices, which it approves COVNA get acceptable by other   companies.       The valves of COVNA are suitable for most fluid, and our company will satisfy   every customer only if he offers correct fluid and the working pressure. In the aspects   ofCquality control, research and development, our solenoid valves are comparable to   advanced-industrial countries. The sound after-sales service is Covna’s purpose.   The dimensions of connection of solenoid valves are from 1/8″ to 4″, as well as the   specification contains thread, flange, normally closed, normally open, and type of   preventing explosion. The material of valve body contains forged copper, casting copper,   cast iron, stainless steel#304, PVC and PTFE, as well as our products are suitable for   the media which are steam, water, air, gas, vacuum, light oil, heavy oil, acid and   alkaline fluid.       The solenoid valve and other valves of our company are widely used in many   devices of mechanical automation, such as water level control, temperature control,   refrigeration and air condition, automatic filling equipment, fire water, irrigation,   SPA, steam path, solar hot water projects, water treatment, environmental    protection equipment, chemical and food machinery industry etc.
