RAPT Digital Regulator & Spunding Valve

This single device can be used in two different directions.  In one direction it can be used as a spunding valve.  Reverse the gas flow through the device and you can turn the same device into a regulator.  When switching from regulator to spunding valve you will also need to select the configuration in the settings menu.

Easy Teardown
This product comes with clips on either side so it' easy to take apart for cleaning.  The housing can be opened without the need for tools.

For Spunding
Digitally control your spunding pressures!  This handy device is one of the last key components to completely digitally control the fermentation process.  Up until now fermentation profiles have been able to use temperature and gravity inputs to vary the temperature through the fermentation but this device gives you the ability to also control pressure both into and out of your fermenter and allows you to completely automate the fermentation process.  Setup profiles that have small amounts of pressure at the beginning of the fermentation process then ramp up the pressure as the fermentation process slows down.  This device has been the missing link in fermentation automation up until now.

For Regulating
This device can be used to digitally control the gas pressure into kegs, fermenters, kegerators or any other pressurised system including compressed air.  This simple device has a multitude of applications.  Simply set the pressure digitally and the valve will open and close to control the pressure into the pressure vessel.

RAPT Connected
As this is a RAPT device it can be registered to the RAPT platform and be used to log, monitor and control the fermentation process remotely.  This device connects directly to your WIFI and can work in conjunction with other RAPT products such as the RAPT Temp Controller, RAPT Pill Hydrometer and the growing family of other RAPT internet connected products.

Integrates into RAPT Chamber
Upgrade your RAPT Fermentation chamber with this device.  This device mounts into the display of your RAPT fermentation chamber so the pressure can be displayed digitally on the front and used seamlessly as the spunding/regulator device on both the left and right hand side of your chamber as you can see below:

Common Specifications (both spunding and regulator mode)
Inlet/Outlet: 8mm (5/16")
Mode: Normally Closed (NC)
Solenoid Coil Voltage: 12V
Solenoid Coil Amp Draw: 1.1 amp
Max Gas Flow Speed: 20l/min (excessive flow rates can cause pressure to build in spunding mode and can cause slow pressure recovery in regulator mode)

Spunding Valve Specifications (When used in this spunding direction)
Pressure rating: 0-1.5Bar (22psi)
Failsafe: YES (when power is off the pressure will still release at 1.5bar (22psi) max

Regulator Specifications (When used in regulator direction)
Pressure rating: 0-8Bar (115psi)
Failsafe: YES (when power is off no gas will flow through the regulator into the pressure vessel)

WARNING: If hops, krausen or other products go through this valve please take it apart and clean immediately.  Blockages from liquid or solids going through the valve can prevent the valve from opening and cause excessive pressure to build up in the fermenter.  The simple solution is to choose a fermenter with adequate head space to prevent this issue.
