Options:
- Operating Pressure: additional (lower) operating pressure options are available, as shown above in the “How to Order” graphic
- Seat/Pilot/Seal Materials: additional seat/pilot/seal material options are available (such as EPR, PCTFE, metal), as shown above in the “How to Order” graphic
- Valve Modifications:
- Manual Throttling (“T” suffix): allows restriction of flow through the valve by reducing the area of the main valve orifice
- Manual Opening (“M” suffix): allows manual opening of the valve in the even of electrical failure
- Position Indicator (“P” suffix): electrical switches that show both the valve open and closed positions for connection to an external control system
Notes:
- Unless otherwise noted, all Atkomatic solenoid valves are designed for installation in a horizontal pipeline with the coil oriented vertically over the pipe center line.
- It is important to locate filters immediately upstream of the valves (with a maximum micron rating of 40 microns) to prevent contamination in the system from causing functional problems with the valves.
- When selecting the product options, if no results are returned the combination is invalid and other selections will need to be made. For example, Steam and Cryogenic applications require Class H coils and TFE or metal seats because of the temperature requirements.
- Contact the Sales Department for replacement coil part numbers and / or repair kit information.
