Siemens Building Technology 658-0014 Valve
The Siemens 658-0014 is a 1-1/4 inch pneumatic radiator valve designed for proportional control of low-pressure steam and hot water in commercial HVAC systems. This Normally Open (NO) angle-pattern valve features a 2 to 6 psi spring range, ensuring precise modulation when paired with a pneumatic controller. Constructed with a heavy-duty brass body and a top-mounted actuator, this valve is engineered for high-cycle reliability in terminal unit applications. Its angle body configuration allows for streamlined installation in tight perimeter heating enclosures, reducing the need for additional piping elbows. The 658-0014 utilizes a replaceable EPDM disc to ensure tight shut-off and long-term durability against seat wear, making it a standard replacement for legacy Building Technologies pneumatic assemblies.
Key Benefits
- Optimized Flow Control: The 1-1/4 inch NPT angle body provides a high flow coefficient for efficient heat transfer in steam or hydronic radiators.
- Broad Compatibility: Standard 2-6 psi spring shift operates seamlessly with most existing pneumatic control systems.
- Durable Construction: Features a rugged brass forge and stainless steel stem to withstand low-pressure steam environments.
- Field Serviceable: Designed for easy maintenance with accessible internal components, minimizing downtime for system calibration.
Common Questions
Is the Siemens 658-0014 suitable for high-pressure steam?
This valve is specifically designed for low-pressure steam and hot water applications; always verify your system's maximum operating pressure against the Siemens technical specifications before installation.
Can I install this valve in a horizontal position?
As an angle-pattern valve with a pneumatic actuator, it is typically installed at the radiator inlet. Ensure the actuator remains upright to prevent condensation buildup within the diaphragm.
What happens to the valve position if control air pressure is lost?
The 658-0014 is a Normally Open valve, meaning it will fail to the fully open position upon loss of pneumatic signal to prevent freezing in cold weather conditions.
