Siemens 259-02068 3-Way Globe Valve 24 Vac (1/2 in)

Product Description

Siemens 259-02068 is a 1/2 in three-way globe valve assembly with a direct-coupled actuator designed for floating (three-position) control on 24 Vac systems. The valve features a 2.5 Cv flow coefficient, brass trim, NPT connections and a linear flow characteristic. The actuator is non-spring return with 200 N force and 0.8 VA power draw for three-position operation. Housing is NEMA 1 suitable for water and water-glycol applications.
