Siemens Building Technology 656-0018 Valve

Siemens Building Technology 656-0018 Valve

The Siemens Building Technology 656-0018 is a professional-grade 3/4" normally open angle valve engineered for the precise proportional control of steam, hot water, and chilled water. Built for terminal unit applications like fan coils, baseboards, and reheat coils, this 2-way pneumatic valve features a 4.6 Cv flow coefficient and a 3-8 psi spring range. Maintenance is streamlined with a design that allows for stem repacking without a complete system shutdown, a critical feature for high-occupancy commercial facilities. The Powermite 656 series utilized in this assembly includes a rugged brass body and stainless steel valve stem to minimize friction and prevent corrosion over long-term service. The compact angle union configuration simplifies installation in confined mechanical spaces, while the dual-sealing packed construction ensures reliable performance in high-pressure environments up to 125 psi. This pneumatically operated valve assembly is a direct solution for contractors requiring a high-flow, fail-safe open component for 2-pipe heating or cooling systems.

Key Benefits
  • Efficient Installation: The compact angle pattern and union nut connection facilitate mounting in tight enclosures and terminal units.
  • Serviceability: Designed with a replaceable soft disc for tight shut-off and a field-replaceable actuator to minimize downtime.
  • High Durability: Features a stainless steel stem and dual-sealing packing to handle service temperatures up to 250°F.
  • Flexible Piping: The pneumatic actuator can be rotated to accommodate air line connections from multiple directions.
Common Questions
  • What is the fail-safe position of this valve? This is a normally open (N.O.) valve, meaning it remains open to flow upon loss of pneumatic control pressure.
  • Can this be used for steam applications? Yes, the 656-0018 is rated for low-pressure steam, as well as water and ethylene glycol solutions.
  • Does the system need to be drained for packing maintenance? No, the top-entry design allows for repacking the valve stem without draining the piping or shutting down the entire loop.
