In this case, it is recommended to check bonnet bolt torque,prior to installation(See the table below). 　Rubber Diaphragm 25.0 {255} 25.0 {255} 25.0 {255} 25.0 {255} 　PTFE Diaphragm 200 （8） 250 （10） Nominal Size Material mm(inch) ▼ Tightening Torque for Diaphragm Valve Bonnet for TYPE 72 Unit:N・m{kgf・cm} DIMENSIONS TABLE ※……Standard dimensions based on PVC material JIS Unit:mm Nominal Size d JIS 10K D1 D2 .
