Features:
- Designed with "Auto Seat Technology"®
- A low rated and fully guided spring allows for more consistent Set Pressures from pop to pop.
- Consistent Set Pressures allows for repeatable use without the need for excessive repairs or resetting.
- Open, Close, Seat and Seal™
- Fully guided disk for the proper alignment, opening and closing, and reseating of the valve.
- Mechanical Stop prevents wear on parts and controls valve lift.
- Pop Action relief allows the valve to go to full lift at Set Pressure. This helps with DOT regulated applications.

- Sour Service Trim available.
- Additional options available to meet NACE MR0175 requirements.
- Canadian Registration Number (CRN)
- Additional options available to meet Conformité Européenne (CE) to PED Directive 2014/68/EU and/or ATEX Directive 2014/34/EU
