No cavities in the flow passage, easy to clean and disinfect for potable water system, etc.
Linear creates seal with mating flanges so no media is in contact with the valve body
Integral ISO 5211 top flange for easy fitting of actuators
Low operating torques results in easy operation and economical actuator sizing
One-piece resilient seat with integral O-ring seal eliminates the need for additional flange gasket
Extended neck design in consideration of construction method and operability
