Armstrong The Brain model DRV40The Brain®
Models DRV40, DRV50, DRV80:

Digital Recirculation Valves (DRV) are designed specifically to be the primary water temperature controller in a continuously pumped circulating hot water system.

Digital technology provides enhanced water temperature control accuracy which resists zero system demand "Temperature Creep" without the use of a manual throttling valve or a temperature activated pump shut-off device (aquastat).

Operational Specifications

  • ± 2°F water temperature control at points of use 25' downstream during demand
  • ± 2°F water temperature control at the DRV during zero system demand "idling" periods
  • 2°F minimum valve inlet to outlet temperature requirement (system recirculation temperature loss)
  • Automatic shutoff of hot water flow upon cold water inlet supply failure
  • Automatic shutoff of hot water flow in the event of a power failure
  • Programmable set point range of 81-158°F (27-70°C)
  • Programmable thermal disinfection mode
  • Programmable 1st level hi/lo temp alarm display
  • Programmable temperature error level for safety shutdown

BrainScan Connectivity

RS485 Port

The integral RS485 Serial Port provides an ability to remotely program the DRV and update the firmware via BS - Connectivity Module or Modbus.

The integral RS485 Serial Port can receive the following outputs from the DRV and communicate them via BS - Connectivity Module or Modbus.

  • Set Point
  • Inlet/Outlet Temperature
  • Over Temperature Alert

The integral RS485 Serial Port can receive the following selfdiagnostic error messages from the DRV and communicate them via BS - Connectivity Module or Modbus.

  • Over Temperature Error
  • PCB Error
  • Thermister Error
  • Motor Error/Emergency Mode
  • Battery Error
BrainScan® Connectivity
 

Water Temperature Control - Connectivity

The integral RS485 Serial Port on The Brain® Digital Recirculating Valve (DRV) can be used to connect the DRV directly to a Building Automation System (BAS) using Modbus RTU or to an optionally selected BS - Connectivity Module which enables interface with a BAS operating on Modbus, BACnetTM or LonWorksTM protocols.

Modbus RTU

When configured for Modbus the DRV becomes a Remote Terminal Unit (RTU). The BAS will need to be using a Modbus RTU format. When connected directly to a BAS using Modbus, the DRV can be assigned a unique network address which is programmed via the integral DB9 external port.

Single Fixture

 

Model 215

Armstrong Rada Model 215Single Fixture Rada Thermostatic Mixing Valve - Model 215:

Thermostatic Mixing Valve of "sealed for life" replaceable cartridge construction. Compact design is ideally suited for use at or near the final point of use to deliver a pre designated mixed water temperature to either a single or a small "group" of lavatories.

Complete operating mechanism is enclosed in a durable disposable polymer cartridge for ease of maintenance. Powerful internal movement of the hot and cold water proportioning mechanism resists mineral deposition.

Capable of close temperature control at diverse flow rates between .5 and 11 gpm (1.9 and 41.6 lpm). Unit is supplied as standard with a tamper proof single temperature "locking" shroud and variable temperature control trim set.*

 

Operational Specifications

  • Typical outlet temperature control ±2°F
  • Adjustable maximum temperature limit stop
  • Adjustable single temperature lockout
  • Thermal shutdown mode upon inlet supply failure

 

 

 

 

 

 

* Use of the trim set allows for full temperature control to within 5°F (2°C) of either inlet supply along with an integral maximum temperature limit stop and single temperature locking option.

Rada Model 320 - FMC/SMC Model 425
Thermostatic Mixing Valve for remote/secure cabinet mount "dead leg" group fixture control. Model 320 is ideal for this application due to its low service, single "sealed for life" disposable cartridge construction, low inlet to outlet temperature differential requirement and low flow single fixture control capability. Model 425 Thermostatic Mixing Valve for institutional group fixture water temperature control. Ideal for recessed enclosure, plumbing chase and utility/mechanical room installation. Powerful internal mechanism and stainless steel operating mechanism resist mineral deposition.
   
Armstrong mixing valve model 425D Armstrong Rada group fixture model 425 - FMC/SMC
Model 425D Rada Model 425 - FMC/SMC
A derivative of the standard Model 425 Thermostatic Mixing Valve for institutional group fixture control. Capable of close temperature control at diverse flow rates between 2 gpm (7.5 lpm) and 49 gpm (185 lpm). Able to blend to within 5°F (2°C) of either inlet supply due to "low seepage" across internal proportioning mechanism. Thermostatic Mixing Valve (TMV) for remote/secure cabinet mount "dead leg" group fixture control. Model 425 is ideal for this application due to its low service, low inlet to outlet temperature differential requirement and low flow single fixture control capability.
