Product Description

Siemens 255-01135 is a 3-way globe valve assembly designed for HVAC water mixing applications. The assembly features a 1.6 Cv valve with NPT connections, brass trim and a direct-coupled actuator that provides 200 N force. It accepts a 0-10 VDC modulating control signal and operates on 24 VAC/DC with a 2.0 VA power draw. The valve is normally closed, rated ANSI Class 250 and NEMA 1 for indoor equipment use.

• 1/2 in. 3-way globe valve with 1.6 Cv and NPT end connections
• Direct-coupled actuator (SSB61U) providing 200 N force; non-spring return, fail-in-place
• 24 VAC/DC input, 2.0 VA power consumption, modulating control 0-10 VDC; suitable for water and up to 50% glycol
