Siemens 255-01137 Globe Valve Assembly 24 VAC/DC (1/2 in.) 599-01137

Product Description

Siemens 255-01137 is a 3-way globe valve assembly with a direct-coupled 200 N actuator designed for modulating control of water and glycol solutions up to 50%. The valve uses a 0 to 10 VDC control signal, operates at 24 VAC/DC with 2.0 VA power consumption, and provides a Cv of 4 with a normally closed fail position and ANSI Class 250 rating.

• 3-way globe valve, 1/2 in. NPT, flow coefficient Cv = 4; brass trim; ANSI Class 250
• Direct-coupled 200 N actuator, non-spring return; modulating control input 0 to 10 VDC; nominal 24 VAC/DC, 2.0 VA
• Modified equal percentage flow characteristic; close-off pressure 40 psi; operating range 34 F to 122 F (1 C to 50 C); NEMA 1 enclosure
