Siemens Building Technology 599-02031 Valve

The Siemens Building Technology 599-02031 is a high-performance 2-way normally open globe valve designed for precise flow regulation in demanding hydronic systems. Featuring a 1/2-inch NPT x Union Male connection, this Powermite MT Series valve body is engineered for terminal unit applications, including fan coils, reheat coils, and induction units. With a 0.4 Cv equal percentage flow characteristic, it ensures linear control across the full stroke, preventing hunting in sensitive HVAC loops. This valve utilizes a forged brass body with brass trim and EPDM O-rings, providing a durable solution for handling hot or chilled water and glycol mixtures up to 50% concentration. Rated for ANSI Class 250 pressure requirements, it supports medium temperatures from 35°F to 250°F. The direct-coupled universal bonnet allows for rapid, tool-free installation of Siemens electronic actuators or pneumatic operators with a 7/32-inch stroke, delivering professional-grade reliability in closed-loop commercial environments.

• Precise Modulation: The equal percentage flow characteristic and 0.4 Cv rating provide stable control for low-flow terminal applications.
• Rugged Construction: Forged brass body and brass trim ensure long-term resistance to de-zincification and mechanical wear.
• Fast Installation: The universal bonnet design allows actuators to be mounted or replaced without the need for specialized tools.
• High Close-off Reliability: Engineered to work with the MT Series actuators to maintain tight shut-off against system differential pressures.

What actuators are compatible with the 599-02031 valve?
This valve body is designed to interface with Siemens MT Series actuators, including the SAS electronic series and pneumatic options that accommodate a 5.5mm (7/32-inch) stroke and provide at least 67 lbf of force.

Can this valve be used for steam service?
While the forged brass body is robust, the brass trim is primarily rated for water and glycol solutions. For low-pressure steam applications (up to 15 psi), a stainless steel trim variant is generally recommended by technicians for better erosion resistance.

What is the proper mounting orientation for this globe valve?
For optimal performance and to protect the electronics, the 599-02031 should be installed with the actuator positioned between the vertical and horizontal plane. Avoid mounting the actuator upside down to prevent moisture or debris from entering the drive mechanism.
