CO-EL-X60 manual hot cold mixing valve

The CO-EL-X60 is a manual hot and cold mixing valve. Used mostly with basins. It has a standard 15mm BSP in and outlet so it will fit all standard plumbing fittings. Not suitable for baths as the flow rate will be limited. This is a manual mixing valve, so the setting must be set beforehand. Make sure that the pressure for both hot and cold water is balanced and that they don’t change. A small lever at the top of the valve (see image) is moved to change the ratio between hot water and cold water is mixed. This is the most affordable mixing valve. Ideal for factories, laboratories and even primary schools where safety is important.

Caleffi thermostatic mixing valve

Made from DZR brass and chrome plated. Adjustable temperature range: 30-65°C with ±2°C accuracy. Maximum static pressure 14bar (Including water hammer), maximum dynamic working pressure 5bar. Maximum inlet temperature 85°C. Maximum inlet pressure ratio (H/C or C/H), 2:1. Minimum temperature difference between inlet hot water and outlet mixed water to ensure optimal performance: 15°C. Minimum flow rate to ensure optimal performance 5l/min. The control knob is used to adjust the temperature in a full turn (360°) between min. and max. It also has tamper protection for locking the temperature at the set value. Do not connect the unit to instant water boilers.

Rada Meynell 15/3 Industrial Thermostatic valve

The Rada Meynell 15/3 thermoscopic mixing valve is specified to meet the highest standards of safety, comfort and economy as demanded by todays users. All Rada products are designed, manufactured and supported in accordance with accredited BS EN ISO 9001:1994 Quality Systems. This item covers all Meynell series manufactured from June 1997. The valve has been certified for use in UK Healthcare premises as a Type3 mixing valve under the TMV3 scheme. Where this product is to be used in such an installation particular Application, Installation, Commissioning and Maintenance requirements apply. These are given in the section ‘TYPE 3 VALVES’.

1/2″ point of use thermostatic mixing valve designed to supply temperature controlled hot water to one or possibly two washbasin outlets.

Normal Operating Conditions are considered as:

  • inlet dynamic pressures nominally balanced.
  • daily usage of 1-6 hours.
  • installation and usage environment not subject to extremes of temperature, unauthorised tampering or wilful abuse.

Pressures and Flow Rates

  • Recommended Flow Rate for Basin Applications: 4 to 6 l/min.
  • Maximum Pressure Loss Ratio*: 10:1.
  • Maximum Static Pressure is 10 bar.

Rada Meynell 15/3 operating temperature range

  • Minimum temperature differential between hot and outlet temperature: 10°C
  • Optimum temperature control range: 35 – 45°C
  • Maximum hot water temperature: 85°C (for safety, a recommended hot water
  • storage temperature maintained below 85°C and for ablutionary installations at between 60 to 65°C).
  • Factory pre-set maximum outlet temperature: 42°C.
  • Minimum temperature differential between hot inlet and pre-set outlet temperature: 10°C.
  • Optimum temperature control range: 35 °C – 45 °C.
  • Maximum hot water temperature: 85 °C (for safety reasons it is recommended that the hot water storage temperature is maintained at between 60°C to 65°C in ablutionary applications).

Flow Control

  • The Rada Meynell 15/3 does not have an integral flow control.
  • Separate outlet flow control such as a tap, mechanical timed flow control device or solenoid is required
  • The device chosen should be non-concussive in operation.


  • Inlet and outlet connectors are 15mm compression
  • Hot (H) and Cold (C) inlets are clearly marked and must be connected this way.
  • The inlet connections have integral strainer and check valve units.

 Maximum Temperature

The maximum blend temperature obtainable by the user should be limited, to prevent accidental selection of a temperature that is too hot. The Rada Meynell 15/3 is fully performance tested, and the maximum temperature is preset to approximately 42°C under ideal installation conditions at the factory. Site conditions and personal preference may dictate that the maximum temperature has to be reset following installation.
