At Last, The return of the highly sucessful Bix 029 gas attenuator. 

When the boiler pressure reaches the pressure set by the control wheel the gas supply to the burner is reduced to a level set by an internal pilot valve.This keeps the burner running at a low heat. maintaining output until the boiler pressure drops. We have developed two versions of this boiler control valve.

WITH 2 AVAILABLE OPTIONS:

• One to use with engines operateing at 5-30 PSI
• And the other with engines operating at 30-80 PSI

They have a full range of adjustment within these parameters. This has been developed in conjunction with Martin Bayliss Engineering, and comes with full fitting and operating instructions. Ideal for steam boats, but can be used on a host of applications. No electronics in sight!
