Industry Applications

• Car Wash: Controls water and chemical delivery with normally open flow.
• Laundry Equipment: Maintains open water/steam flow when de-energized, ideal for rinse cycles.
• Air Compressors: Keeps air lines open when not powered, suitable for venting and bypass.
• Industrial Water Control: Reliable for fail-open designs in process lines.
• Pumps: Supports open flow control in pump discharge circuits.

Compliance and Approvals

• UL Listed (where applicable)
• CSA Certified
• CE Compliant (RedHat II versions)

Installation and Operational Notes

• Install in any direction; vertical mounting improves performance and service life.
• Check system voltage and coil type for proper matching before energizing.
• Explosionproof models require approved enclosures where hazardous locations are involved.
• Always confirm system fluid, pressure, and temperature compatibility before installation.
• Regular maintenance is recommended to keep sealing surfaces clean and ensure valve reliability.
