Solenoid Valve

Solenoid valves are electrically activated valves, typically used to control the flow of water in cultYvate IoT systems. It serves the purpose of removing the need for an engineer to operate a valve manually.

Solenoids operate using an electromagnetic solenoid coil to change the state of a valve from open to closed, or vice-versa.

Built robustly to handle the rigours of commercial sites, these valves are virtually indestructible. This model features durable high-grade construction and a rugged diaphragm with support to prevent stress failure.

Features

  • Heavy-Duty: PGVs are built to handle well over 150 GPM
  • Reliable: High-grade construction and rugged diaphragm provide unmatched performance
  • Dynamic: Maximize efficiency and prolong system life by the fine-tuning flow.
  • External and internal manual bleed allows quick and easy “at the valve” activation
  • A double-beaded diaphragm seal design for superior leak-free performance
  • Optional DC latching solenoids enable battery-powered controllers
  • Captive bonnet bolts provide hassle-free valve maintenance
  • Encapsulated 24 VAC solenoid with captive plunger for hassle-free service
