Orbit 1" Electric Straight Inline Valve. It features a 1" NPT connection, no flow control, a manual on/off bypass lever, and works with standard residential 24V sprinkler systems. Made of durable acrylonitrile butadiene styrene (ABS), this valve withstands maximum pressure of 150 psi. Installed below ground, it is compatible with PVC pipe material. Its soft-close design reduces water hammer and wear on the system, while the reverse flow fail-safe design prevents flooding. Captured lid screws, solenoid plunger, and attached diaphragm spring ensure easy maintenance. Replaces all major brands of sprinkler valves. For use with outdoor cold water irrigation systems.
