Description

The Siemens 264-02000 MT Series two-way globe valve assembly is designed for modulating control of water and low-pressure steam in commercial HVAC applications. The normally closed configuration provides positive shutoff when the actuator is de-energized, making the assembly well-suited for zone control, terminal units, and small-capacity coil applications that require precise low-flow modulation in building automation systems.

Construction pairs the 599-02000 globe valve body with the SQS65U electronic actuator. The 1/2" body carries an ANSI Class 250 pressure rating with brass trim for compatibility with standard hydronic media. Flow capacity is rated at 0.4 Cv, supporting fine-tuned modulation in low-flow circuits. The SQS65U actuator accepts a 0-10 VDC control signal for proportional positioning by a building automation system.
