Hydraulic valve
Urinal flush control valves
The hydraulic valve is an automatic urinal flush control valve. The valve uses a simple patented mechanism which prevents water waste by ensuring that the auto-flush cistern is only filled, and can only flush, when the washroom is used.
- Automatic urinal flush control
- Unique patented hydraulic mechanism – no electrical supply or batteries required
- Industry leader with half a million already installed
- ‘Fit and Forget’ quality and reliability
- Hygiene flush option for periods of non-use
- Ensures compliance with the Water Regulations
- On DEFRA’s ECA Water Technology List; purchase and installation are tax deductible
- Reduces water consumption and washroom odours
Product Description
- The valve is installed on the supply pipe to the urinal cistern.
- The installer or user can adjust the time the valve remains open and therefore how long the cistern takes to fill and how much water is used. When the washroom is not being used the water supply pressure remains constant and the valve remains closed preventing water passing into the cistern.
- The cistern can therefore only flush during periods when the washroom is in use, eliminating unnecessary water consumption and cost.
Choosing the right valve for your application
Three models make up the range of hydraulic valves, each suited to a different range of water supply pressure. This table will help to specify the right model for your application.
