Siemens 2-Way Normally Open Brass Zone Valve

The Siemens 2-Way Normally Open Brass Zone Valve is a two-way zone control valve for hydronic heating and cooling systems. It is part of the Siemens Building Technology 599 Series zone valve line. The brass-body construction is sized for individual zones and terminal units. It is a durable water valve for HVAC and building automation work.

Key Features:

• 2-way, normally open design: the valve stays open when the actuator is not driving it closed, so flow continues if control power is lost.
• Brass construction: the brass body and brass trim resist corrosion and hold up well in water-based systems.
• Threaded NPT connections: these allow straightforward installation in standard hydronic piping.
• Globe-style, equal percentage flow: this gives stable, predictable control of water flow through a zone.
• Electronic actuator control: the valve is designed to work with Siemens electronic actuators for zone temperature control.
• Water service: suited to hot and chilled water applications, including water with anti-freeze.

Siemens Building Technology products are widely specified in commercial and institutional HVAC systems. This valve line gives reliable zone-level control for fan coils, unit heaters, radiators, and similar terminal equipment.
