Features:

Designed with features of "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.
Non-rising stem allows valves to be installed in small spaces.
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
