Siemens Building Technology 599-00210 Valve Body

The Siemens 599-00210 is a heavy-duty 2-way zone valve body engineered for high-performance hydronic systems. Featuring a 1/2" NPT connection and a 1.0 Cv rating, this brass-trimmed valve body is built for precise control in hot and chilled water applications, including fan coil units, baseboard heating, and VAV terminal boxes. Designed with a linear flow characteristic, it ensures consistent modulation even under varying delta-P conditions. This 599 series zone valve utilizes a direct-coupled universal bonnet, allowing for tool-free installation of SFA, SFP, SSA, or SSP series electric actuators. The robust brass body is rated for ANSI Class 125, supporting temperatures from 34°F to 230°F. The stainless steel stem and EPDM O-ring packing ensure long-term reliability against glycol solutions up to 50%, making it a standard choice for technicians seeking a primary HVAC control valve for tight-space mechanical assemblies.

• Universal Compatibility: Direct-coupled bonnet allows the Siemens 599-00210 to pair seamlessly with SFA/SFP and SSA/SSP series actuators without requiring specialized mounting hardware.
• Precise Capacity Control: The 1.0 Cv rating and linear globe-style stroke provide accurate throttling for low-flow terminal unit requirements.
• Reliable Media Handling: Engineered with brass trim and an ASTM A582 stainless steel stem to resist corrosion in 50% water-glycol mixtures.
• Technician-Friendly Design: Features a manual override capability (with hex wrench) and a visual position indicator for easy troubleshooting on-site.
• Durability: ANSI Class 125 rating ensures the 1/2 inch NPT valve body withstands static pressures up to 125 psi in demanding commercial HVAC loops.

Is the actuator included with the Siemens 599-00210? No, this is the valve body only. You must pair it with a compatible Siemens SF or SS series actuator depending on your control signal requirements (2-position, 3-position, or 0-10VDC).

Can this valve be used for steam applications? No, the 599-00210 is specifically designed for water and glycol solutions. For steam applications, a valve body with a higher temperature rating and specialized packing is required.

What is the close-off pressure for this 1/2" NPT zone valve? When paired with the appropriate Siemens actuator, the 599-00210 typically achieves a close-off pressure of approximately 44 psi, ensuring no leakage in standard zone control configurations.
