Description

Series 800 Pressure Only vent valves are designed to relieve pressure only through the vent line. By omitting the vacuum side of the valve they
eliminate the possibility of a two way flow. These are designed the same as the “SO” pressure/vacuum series except they eliminate the vacuum side of the valve. All valves are lined and trimmed with plastic where moving parts or surfaces may become fouled by crude gasses or materials.

 

Features & Benefits

• All intemal working parts are made from a “PPS” (Polyphenylene Sulfide) plastic material for superior corrosion resistance which resists freezing and sticking with operating ranges from -45° C to 260° C.
• Multiple setting options by adding additional pressure weights

• Viton gaskets for “Sour Gas” and corrosive service applications
• Non-Corrosive coating option for extremely harsh environments
• Certified flow capacities in accordance with API

  • Sizes Available: 2″ through 4”
