- Lower maintenance costs due to design that utilizes two adjuster fasteners that permit in-line seal adjustments under pressure within seconds
- Low fugitive emissions through fluoropolymer reverse-lip diaphragm that provides a pressure-activated, self-energizing dynamic and static stem seal
- Compatibility with a range of Automax actuators and other instrumentation
- Options for lethal, toxic and sub-zero fluid services plus process control and high flow requirements
