Siemens 259-02026 Globe Valve Assembly 24 VAC 0.8 VA (1/2 in) 599-02026

Product Description

Siemens 259-02026 is a 2-way globe valve assembly with a 1/2 in NPT connection and a 4 Cv flow capacity. It includes stainless steel trim and a direct-coupled, non-spring-return actuator that provides 200 N force. The assembly operates at 24 VAC with 0.8 VA consumption, offers normally closed floating 3-position control, and is suitable for water, water-glycol (to 50%), and low-pressure steam below 15 psi.

• 24 VAC operation, 0.8 VA power consumption; normally closed, floating 3-position control
• Direct-coupled, non-spring-return actuator with 200 N force; modified equal percentage flow characteristic
• Stainless steel trim, 4 Cv flow capacity, ANSI Leakage Class IV; 1/2 in NPT (female x union male) connection
