Siemens Building Technology 658-0012 Valve
The Siemens Building Technology 658-0012 is a heavy-duty 1" N/O pneumatic radiator valve engineered for proportional control in two-pipe steam or hot water heating systems. As part of the professional-grade Siemens Powertop 658 Series, this angle union valve features a 10 Cv flow coefficient and a field-tested 2-6 psi spring range. Designed for the rigors of commercial mechanical rooms, the unit includes a stainless steel stem for enhanced durability and a large diaphragm area that ensures high control accuracy and positive close-off against 15 psi main pressure. The normally open configuration and equal percentage plug profile provide stable modulation for terminal units such as unit ventilators, reheat coils, and fan coils in high-demand environments like hospitals and schools. This 1-inch assembly utilizes a 1" IPF x 1" IPM union nut and nipple connection, allowing for straightforward integration into existing HVAC pneumatic control loops.
Key Benefits for Technicians- Enhanced Controllability: The equal percentage flow characteristic and long stroke design allow for precise temperature regulation in hydronic and steam applications.
- Serviceability: Features a removable pneumatic actuator that can be rotated to accommodate tight piping configurations and replaced without disturbing the valve body.
- Inline Maintenance: The 658-0012 valve is designed to be repacked while the system remains pressurized, reducing downtime during routine service calls.
- Industrial Build: Utilizes a brass valve body and stainless steel trim to resist corrosion and handle media temperatures up to 250°F.
What is the maximum pressure rating for the Siemens 658-0012?
This Poptop series valve is rated for a maximum fluid pressure of 300 psig and is suitable for steam applications up to 15 psig.
Can the actuator be replaced without removing the valve from the line?
Yes, the Siemens Powertop 658 design facilitates quick actuator removal and rotation to simplify both initial valves installation and long-term maintenance in restricted spaces.
Is this valve compatible with glycol solutions?
The Siemens 658-0012 is fully compatible with water, steam, and ethylene glycol solutions up to a 50% concentration.
