The GBS25 solenoid raises the bar on solenoid technology and is a "must have" for any golf course that experiences surges due to lightning or uses non-potable water. The GBSS25 is the standard solenoid included on all currently available Rain Bird golf valve-in-head rotor models. It provides superintendents with a solution for two potential service issues often faced by valve-in-head solenoids: resistance to lightning surges and resistance to debris. The GBS25 has the highest surge resistance in the industry and is rated for 25,000 volt surges. It also has a secondary filter that protects the solenoid chamber from debris, keeping the plunger captured and away from contamination.
