The Mercer 8100 Series Threaded Pressure Relief Valve is “State of the Art” in soft seat, high flow rate, pressure relieving devices. The 8100 Series spring operated pressure relief valve incorporates Mercer’s patented “Auto Seat Technology”® into its design. This design incorporates a fully guided disk, and a low rated guided spring to reduce stress on the spring, giving you a consistent, repeatable set pressure, which will continually outlast the competition. The soft seated 8100 Series has a field-proven lip seal design, which allows for a tighter seal up to set pressure. The non-rising stem allows for a shorter bonnet, which is lighter and more compact.

Features
