Orbit 57281 Inline Solenoid Valve 1 Inch 24V Irrigation

Product Description

The ORBIT 57281 is a 1-inch inline solenoid valve designed for irrigation and secondary water systems. Rated to 120 psi and operating on a 24-volt low-voltage solenoid, it controls water flow in landscape and agricultural irrigation lines. The body and lid are molded from heavy-duty, UV-protected PVC that meets NSF 14 standards. The diaphragm is a molded thermoplastic elastomer listed to NSF 61, making this valve suitable for culinary and potable secondary water applications. Installation and service are handled by licensed irrigation contractors or qualified plumbers.

The 57281 is intended for residential and light commercial irrigation systems where a reliable, low-voltage inline valve is required. Its internal bleed port allows manual operation without powering the solenoid, which is useful during system commissioning and troubleshooting. The balanced diaphragm design maintains consistent operation across a wide pressure range up to 120 psi. This valve is well-suited for drip systems, zone control manifolds, and secondary or culinary water distribution lines that require NSF-compliant wetted materials.

Compatibility

Designed as an OEM-style inline solenoid valve for 1-inch irrigation zone control and secondary water systems requiring 24-volt low-voltage actuation and NSF-compliant wetted materials.

Installation Notes

Installation should be performed by a licensed irrigator, plumber, or qualified technician in accordance with applicable local plumbing and irrigation codes. Shut off the main water supply and de-energize the irrigation controller before removing or installing the valve. Ensure proper flow direction as indicated on the valve body. Low-voltage wiring connections to the controller should follow the irrigation system wiring schematic and comply with NEC low-voltage guidelines.
