Overview: Siemens 599-00214
The Siemens 599-00214 is a 599 Series 2-way, 1/2 in. NPT zone valve body (Cv 4.0, Kvs 3.4) with a direct-coupled universal bonnet that accepts Siemens SFA/P Series, SSA or SSE/F Series electric actuators. The actuator is ordered separately and determines whether the valve is normally open or normally closed.
NPT 599 bodies are also offered as factory valve and actuator assemblies, ordered by adding a 3-digit actuator prefix code to the body suffix (for example 240-00214 with the SFA11U).
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.
Best For
- Hot or chilled water zone control: zones with radiators, floor heating by manifolds, fan coil units, induction units, cooling ceilings, wall-mounted boilers, VAV applications
- Water and glycol solutions to 50%, 34 to 230 °F

Frequently Asked Questions
What is the Cv of the Siemens 599-00214?
The 599-00214 has a Cv of 4.0 (Kvs 3.4) in a 1/2 in. NPT 2-way 599 body with a linear flow characteristic.
Which actuators fit the Siemens 599-00214?
The 599-00214 accepts Siemens SFA/P Series (SFA11U, SFP11U, SFA71U, SFP71U), SSA Series (SSA81U) and SSE/F Series (SSE161.05U, SSF161.05U) electric actuators on its direct-coupled universal bonnet.
Is the Siemens 599-00214 normally open or normally closed?
The actuator determines it. SFA11U and SFA71U make the 2-way valve normally closed, SFP11U and SFP71U make it normally open, SSA81U is normally closed, SSE161.05U is normally closed and SSF161.05U is normally open.
What is the close-off pressure of the Siemens 599-00214?
Maximum close-off (AB-A) depends on the actuator: 51 psi with SFA, 44 psi with SFP, 65 psi with SSA81U and 75 psi with SSE/SSF actuators.
Can the Siemens 599-00214 be ordered as a factory assembly?
Yes. Add the actuator prefix code to the body suffix: 240-00214 (SFA11U), 241-00214 (SFP11U), 242-00214 (SFA71U), 243-00214 (SFP71U), 244-00214 (SSA81U), 245-00214 (SSE161.05U) or 248-00214 (SSF161.05U).
How should the Siemens 599-00214 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 599-00214 rated for?
Water and glycol solutions to 50%, medium temperature 34 to 230 °F (1 to 110 °C), maximum inlet pressure 232 psig.
