Overview: Siemens 244-00213
The Siemens 244-00213 is a factory-assembled 599 Series 2-way, 1 in. NPT zone valve (Cv 7.0, Kvs 6.0) with a Siemens SSA81U 24 VAC 3-position (floating) actuator. The assembly is normally closed, and the fail-in-place actuator holds valve position on loss of power.
The 2-way body has a linear flow characteristic and a 1/10 in. (2.5 mm) stem stroke, sized for hot and chilled water zone control.
Specifications verified against Siemens 599 Series Submittal Sheet 154-034 (February 1, 2023); Valve Body Technical Instructions 155-320P25 (December 8, 2022); Assembly Selection Technical Bulletin 155-291 (February 3, 2023). Last reviewed October 11, 2026.

Frequently Asked Questions
What is the Cv of the Siemens 244-00213?
The 244-00213 has a Cv of 7.0 (Kvs 6.0) in a 1 in. NPT 2-way 599 body with a linear flow characteristic.
Is the Siemens 244-00213 normally open or normally closed?
Normally Closed. The SSA81U is a fail-in-place actuator, so on loss of power the valve holds its last position.
What power and control signal does the Siemens 244-00213 use?
The SSA81U runs on 24 Vac ±20%, 50/60 Hz, draws 0.8 VA, and accepts a 3-position (floating) control signal.
What is the close-off pressure of the Siemens 244-00213?
36 psi maximum close-off (AB-A), rated according to ANSI/FCI 70-2, with leakage rate ANSI Class III (AB-A).
How should the Siemens 244-00213 be installed?
Install so flow follows the arrow on the valve body. For best performance mount the actuator above the valve body; any position between vertical and horizontal is acceptable, but not below horizontal or upside down.
What media and temperatures is the Siemens 244-00213 rated for?
Water and glycol solutions to 50%, medium temperature 34 to 230 °F (1 to 110 °C), maximum inlet pressure 232 psig.
