Siemens Building Technology 599-03079 Valve

The Siemens Building Technology 599-03079 is a heavy-duty 1 1/2" NPT globe valve engineered specifically for high-demand hydronic and steam applications. Featuring a 2-way normally closed configuration and a 25 Cv linear flow characteristic, this valve ensures precise modulation in terminal unit control. The bronze body is paired with stainless steel trim and specialized high temperature packing, making it capable of handling media temperatures up to 337°F, including saturated steam up to 15 psi. As part of the Flowrite 599 series, it utilizes a direct-coupled universal bonnet that allows for seamless integration with 3/4 inch stroke actuators, whether pneumatic or electronic, without the need for complex linkages. With an ANSI Class 250 rating and Class IV leakage performance (0.01% of Cv), this valve provides the tight shut-off and industrial-grade durability required by veteran pipefitters and building automation contractors managing large-scale HVAC systems.

• Rugged Material Profile: The combination of a bronze body and stainless steel trim resists corrosion and wear in aggressive water-glycol solutions and steam environments.
• High Temperature Performance: Equipped with premium packing rated for up to 337°F (170°C), ideal for high-pressure hot water and low-pressure steam service.
• Precise Flow Control: A linear flow characteristic and a 25 Cv rating provide predictable performance across the entire 3/4-inch stroke of the actuator.
• Field Serviceability: Designed with a cartridge-type packing and a fully serviceable internal assembly to minimize system downtime during routine maintenance.
• Universal Compatibility: The normally closed design works natively with a wide range of Siemens Flowrite actuators, simplifying inventory for mechanical contractors.

What media is compatible with the 599-03079?
This valve is designed for use with water, water-glycol solutions up to 50%, and saturated steam up to 15 psi.

What stroke length is required for the actuator?
The 599-03079 is designed to operate with any pneumatic or electronic actuator featuring a 3/4-inch (20 mm) stroke.

Can this valve be field-repaired?
Yes, the valve is fully serviceable, and rebuild kits are available to replace the stem packing or internal trim components without replacing the entire bronze body.
