These high quality valves have many design advantages. One of these is the 2 piece body design that allows for easy maintenance and repair. Also, the Chem-Flow Series contains a pure PTFE-covered stainless steel disc for high corrosion resistance and purity. Another measure that prevents corrosion in these butterfly valves is the epoxy coated body. They also have low operating torque which allows for ease of automation. The wide, chamfered sealing surface prevents radial cold flow of liner under flange bolting forces; this eliminates the need for any additional gaskets.

Max-Seal’s Chem-Flo Series valves are pressure tested according to DIN 3230 Part 3, EN 12266, and API 598. All materials and test certificates are maintained according to EN 10204-3.1B. Spark testing of disc encapsulations and liners is carried out according to DIN IEC 243T2 standards.

Max-Seal has designed the operator mounting top plate to ISO 5211 specifications for direct mounting of manual operators and actuators. The square stem connection is designed to recognized industrial standards. This stem provides a secure connection with almost all actuators without requiring any brackets. Max-Seal’s range of automation products is extensive and includes handles, gear operators, pneumatic actuators, electric actuators, pneumatic positioners, and more.
