Siemens Building Technology 599-02044 Valve

For high-demand terminal unit applications, the Siemens 599-02044 is a professional-grade 3/4 inch globe valve designed for precision control in hydronic systems. This 2-way normally open valve features a 6.3 Cv flow coefficient and a modified equal percentage characteristic, ensuring stable heat transfer across various load conditions. Constructed with a forged brass body and durable brass trim, this NPT threaded valve is engineered to withstand an ANSI Class 250 pressure rating, making it ideal for the control of hot or chilled water and technical glycol solutions up to 50%. The Powermite 599 MT Series architecture incorporates a direct-coupled universal bonnet, allowing for seamless integration with pneumatic or electronic actuators without the need for specialized tools. This HVAC zone valve operates within a wide medium temperature range of 35°F to 250°F, providing veteran technicians with a reliable solution for convectors, fan coil units, and reheat coil maintenance or new installations.

• Optimized Flow Control: The modified equal percentage plug design prevents hunting and improves coil performance in modulating service.
• Rugged Construction: Built with a forged brass body and EPDM O-ring packing for long-term leak protection and compatibility with high-pressure systems.
• Universal Compatibility: The direct-coupled bonnet facilitates fast mounting for any Siemens MT Series actuator, reducing onsite labor time.
• ANSI Class 250 Rated: Engineered for demanding environments with a high rated close-off and robust 3/4" NPT connections.

What is the fail-safe position of this valve body?
The 599-02044 is a normally open (NO) valve, meaning the flow remains unobstructed when the actuator is de-energized or the spring is in its relaxed state.

Is this valve suitable for steam applications?
This specific model utilizes brass trim and is recommended for water and glycol solutions. For low-pressure steam applications up to 15 psi, a stainless steel trim variant is generally required.

What actuators are compatible with the Powermite 599 MT Series?
This valve body is designed to integrate with electronic (SSC or SAS series) and pneumatic (2-inch) actuators with a 7/32-inch stroke and 67 lbf minimum force.
