Rubber lined butterfly valve with pneumatic actuator
GMK has a rubber-lined butterfly valve with pneumatic actuator that utilizes a structure that is rubber-lined throughout the central line cavity. To effectively prevent corrosion of the valve caused by media, the body and disc are lined with synthetic rubber, or the body is lined with rubber such as EPDM, NBR, and the disc is made of high-quality alloy steel, Stainless steel, or UB6 904l, amongst other materials. This valve has a characteristic called bubble-tight that assures a great seal by limiting linear movement and providing exceptional reliability over thousands of cycles. This feature also gives excellent durability. This valve has a working temperature range that goes from -30 degrees Celsius to 180 degrees Celsius.
