RAVI Thermostatic Cylinder Controls



- Simple, self acting control, requires no wiring
- Versions available for Pumped and Gravity systems
- 2-port Pumped versions in 15mm and 22mm sizes
- 2-port Gravity versions in 22mm and 28mm sizes
- 3-port Pumped versions in 15mm or 1/2” BSP sizes

The RAVI offers a simple non-electric alternative to the more traditional motorised valve and electric cylinder thermostat, and is available in 2-port versions for pumped and gravity systems, and in a 3-port version for pumped systems.

To ease installation, the sensor is designed for 'clamp-on' mounting, using a strap and adhesive pad provided. For situations that demand immersion sensing, an immersion pocket capillary gland seal is also available.
