Norriseal Series 2220/2200 High Pressure Control Valve

Home | Products | Norriseal Series 2220/2200 High Pressure Control Valve

Proven, “industry-standard” high-pressure control valve. Used to control liquid or gas pressure in separators, scrubbers or other types of pressure vessels.

Both Series 2200 and 2220 valves can be furnished with a variety of trims and end connections.

The Series 2200 has an open yoke which allows mounting of positioners, limit switches and other devices. It is also used in applications that require an exposed stem for accurate travel indication. The yoke allows the valve to be used for higher temperature ranges.

The Series 2220 is the close-coupled or yokeless, space saving version of the Series 2200. This series is ideal for controlling liquids on compressor scrubbers and housed production separators where space is at a premium.

  • Close-coupled design conserves space

  • Variety of trims, seal materials, and end connections
