General Application Figure 990(wafer)and Figure 920(lug) are used when sanitary service or corrosion resistance is required.Heavy duty applications include chemical,food and beverage, pharmaceutical,pulp and paper, mining and power industries. Available with PTFE lining for light corrosive services and rubber lining Technical Data Flange Standard for light abrasive services.
