• Advanced seat and disc design provide bubble-tight shutoff while maintaining a low seating torque

• Standard rotary actuators, or industrial grade NEMA 4 actuators for a variety of application requirements

• Internal valve body five bushing design isolates the valve body from the shaft resulting in better control

• Standard stainless steel disc and shaft for strength, durability and long-lasting operation
