The Infrared Control Valve IRC® automatically manages the supply of water to a urinal cistern. The unit employs motion-sensing infrared to control valve operation and reduce water consumption by over 80%. The PIR sensor detects movement and activates the solenoid valve, allowing water into a urinal cistern.
And now the best is even better. Incorporating the same proven and robust brass valve, new features include a stylish and compact body shape, an economy mode option to provide even greater water savings and a design which allows easy-to-use battery replacement.
The solenoid assembly is plumbed in on the water supply to the urinal cistern. The connection to the infrared sensor is made either by directly mounting the sensor module on to the solenoid or by using the ‘floating socket’ supplied for a remote mounting. If mounted remotely, the sensor module may be:
- Surface mounted.
- Recessed into a suspended ceiling using the cutting template and mounting bracket, supplied with the IRC® as standard.
If the sensor detects no occupancy in 12 hours it will automatically open the valve for 30 minutes to allow one flush of the cistern to rinse the urinals and pipework.
The sequence is designed to maximise battery life, giving approximately 3 years’ life from one good quality set of batteries.
The flow rate of the water into the cistern is adjustable to maximise water economy. Generally this should be set so that the cistern flushes once every time the valve is opened i.e. every 30 minutes during occupation.

The IRC® urinal flush control consists of a solenoid valve and the infrared sensor module.
When the IRC® detects movement in the washroom, a pulse from the sensor opens the normally-closed solenoid valve and water flows to the cistern. The LED flashes to show the valve is open.
In Normal mode, the IRC® operates with a 30-minute cycle. This means that the cistern will flush a maximum of 2 times per hour.
In Economy mode, an additional delay of 15 minutes is provided before the Normal mode operating cycle is activated, to save even more water. This means that the cistern will flush a maximum of 2 times in 90 minutes.
