Why Retrofit?
Water damage prevention solutions have been available for a long time, but most reliable solutions require a licensed installer to cut your pipes and install an inline device. Electronic devices have a much short life span than plumbing, and if they malfunction, it can be costly and stressful to fix.
Retrofit solution is an ideal way to circumvent these issues, however it’s tricky to find the right solution
Common problems from legacy designs
• Unreliable single sided mounting on pipe/valve
• Perpendicular movement only
• Fixed & limited torque
• Indoor use only
In legacy designs, the Handle Driver will apply force to the Valve Handle to conduct valve actuation, as a result the same amount of counter torque will also convey back to the Pipe Clamp through a leveraging path, by physic this stress is multiplied by the distance between Handle Driver and Pipe Clamp which equivalent to effect of Moment Arm.
Other challenges from real world
• Due to wear and tear not all valves handles turns perfect perpendicular
• Rusted/old valves needs big torque beyond legacy design’s ability

Custos - Simple yet Sophisticated
Installation process is as simple as 1-2-3 and does not require any tools, making it accessible for everyone!
The Custos retrofit valve servo mechanism is considered by many to be the best in production. This second generation has been upgraded in every aspect and strikes a good balance between size and adaptability to fit various ball valve shapes and sizes.
Gone are the days where reliability and easy installation for retrofit valve servos were a dilemma; now, they are a reality.
Developing a retrofit valve servo that can effectively operate the diverse range of valves from various manufacturers, in different ages and conditions, is a notable challenge. The presence of rust on valves can make them incredibly difficult to manipulate, while others may require minimal effort.
Moreover, valves may not rotate at a perfect right angle, and their rotation distance may vary due to wear and tear. As a result, mechanics may struggle to determine the appropriate amount of torque needed to turn a stubborn valve without overloading the more manageable ones.
We have devised a solution to tackle these challenges, which represents a significant advancement in valve torque control systems.
Our patented micro-electro-mechanical powertrain, coupled with cutting-edge microprocessors and our proprietary control algorithm, has enabled self-adaptation for precise torque control and turning span required to manoeuvre any valve accurately to its desired position.
With our intelligent adaptive valve torque control system and control method, mechanics can now work more effectively and proficiently, without the frustration of struggling with stubborn valves or damaging the easier ones.
