Siemens Building Technology 658-070 Assembly
The Siemens Building Technology 658-070 Assembly is a precision-engineered VP658 1/2" REPL TOP ASSY designed for field-level restoration of Powertop series pneumatic valves. As a direct replacement actuator and trim, this kit allows technicians to rebuild the upper operating section of 1/2-inch Siemens pneumatic valve assemblies without needing to pull the entire valve body from the line in many normally open configurations. This HVAC valve repair kit features a high-performance stainless steel valve stem and a heavy-duty diaphragm designed to maintain tight close-off and accurate pneumatic flow control within terminal units, including fan coils, induction units, and reheat coils.
For contractors managing 658 series Powertop valves, the 658-070 provides a 2.5 Cv capacity and is specifically calibrated for Siemens building automation environments where responsiveness and long-term durability are critical. Utilizing this genuine OEM replacement part ensures full compatibility with existing pneumatic actuator housings, preserving the equal percentage plug characteristics required for stable temperature modulation. Whether you are performing routine HVAC system maintenance or addressing a failed 1/2" 2-way assembly, this top assembly provides the structural integrity needed to withstand the high-cycle demands of commercial air handling applications.
Key Benefits- Field-Serviceable Design: Complete VP658 1/2" REPL TOP ASSY allows for rapid internal component replacement to minimize system downtime.
- Engineered Precision: Features a stainless steel valve stem and a large diaphragm area for superior control accuracy and reliable seating.
- Broad Compatibility: Drop-in replacement actuator and trim specifically for 1/2" 658 Series Powertop valves with a 2.5 Cv rating.
- Performance Integrity: Maintains original pneumatic flow control specifications for chilled water, hot water, and low-pressure steam applications.
Is this assembly compatible with 3-way valves?
The 658-070 is primarily designed as a replacement actuator for 1/2-inch 2-way 658 series valves. For 3-way sequence or changeover valves, verify your specific model number, as these may require different rebuild kits such as the 658-405.
Can I replace the diaphragm separately using this kit?
While this kit contains the complete top assembly, if only the diaphragm is compromised, individual replacement diaphragm kits are available. However, replacing the entire 658-070 assembly is often more efficient for older units where stem wear is also a concern.
Does this include the lower valve body?
No, this is a VP658 1/2" REPL TOP ASSY, which includes the operating head, stem, and trim components. It is intended to be threaded into your existing 1/2" valve body.
