Siemens Building Technology 656-833 Replacement Top
The Siemens 656-833 Replacement Top is a direct-fit pneumatic actuator assembly designed specifically for Siemens Powermite 656 Series angle and flared valves. Engineered for precise terminal unit control, this replacement unit features a 3 to 8 psi spring range and is configured for Normally Open (NO) operation. As a core component of the Siemens Building Technology pneumatic portfolio, the 656-833 facilitates reliable proportional control of hot or chilled water and low-pressure steam in 1/2-inch line size applications. The rugged construction of this replacement actuator and trim ensures a high Cv rating of 0.5, maintaining optimal flow characteristics in demanding commercial HVAC configurations. For technicians performing field repairs, this VP656 replacement top integrates seamlessly with existing valve bodies to restore factory-standard performance without the need for full valve replacement, minimizing system downtime and labor costs during pneumatic valve maintenance.
Key Benefits
- Ensures accurate proportional control within a standard 3-8# spring range for consistent HVAC performance.
- Designed for Normally Open (NO) failsafe operation, providing safety in heating and cooling sequences.
- Specifically compatible with Siemens 656 Series and Powermite 656 valve bodies.
- Includes the replacement actuator and trim assembly for a complete top-side overhaul.
- Rugged Siemens Building Technology engineering provides durability in high-cycle terminal unit applications.
Common Questions
Which valve bodies are compatible with the 656-833?
This replacement top is engineered exclusively for Siemens Powermite 656 Series 1/2-inch flared and angle valves often used in induction units and fan coils.
Does this unit include the valve body?
No, the Siemens 656-833 is a replacement top only. It includes the pneumatic actuator and internal trim components but is designed to be installed on an existing 1/2-inch valve body.
What is the default position of the valve with this actuator?
This model is Normally Open, meaning the valve remains open when no pneumatic pressure is applied to the VP656 actuator.
