9100 Series Flanged Pressure Relief Valve
Brand: Mercer ValveThe Mercer Valve 9100 Series Pressure Relief Valve is “State of the Art” in soft seat, high flow rate, pressure relieving devices.
The 9100 Series is a continuation of the 8100 Series incorporating our patented “Auto Seat Technology”® into its design.
Mercer Valve’s “Auto Seat Technology“® has made the 9100 Series an industry leader with its reliable, repeatable set pressures.
The patented soft seat design and fully guided disk allow the valve to continually outlast the competition.
The soft seat 9100 Series has a field-proven lip seal design, which allows for a tighter seal up to set pressure.
This tight seal reduces leaks and limits product loss.
The 9100 Series is manufactured in accordance with the requirements of ASME Boiler and Pressure Vessel Code, Section VIII, Division 1 for Air/Gas and Liquid service.
The 9100 Series is well suited for specialty gases, compressors, separators, transmission, gathering lines and other production processes.
Features- Designed with "Auto Seat Technology"®.
- Consistent Set Pressures allowing repeatable uses without repair or resetting.
- Open, Close, Seat and Seal™.
- Fully guided disk keeps the disk properly aligned, opening and closing, helping to reseat the valve.
- Mechanical Stop prevents wear on parts and controls valve lift.
- Low rated and fully guided spring allows for more consistent set pressures from pop to pop.
- Pop Action relief allows valve to go to full lift at set pressure. Helps with DOT regulated applications.
- Built in accordance with the requirements of ASME Boiler and Pressure Vessel Code. Sec. VIII Div 1.
- Non-rising stems allowing valves to be installed in small areas.
