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 TFE or metal seats because of the temperature requirements.
- Buna-N, Viton and EPR seats are limited to 500 psig.
