Thermostatic valves
Thermostatic valves are used in hospitals, clinics, food industry, homes and factories. They are also sometimes called safety valves. A thermostatic valve mixes hot water from a geyser (usually at temperatures (± 70°C) with cold water providing the user with warm water below scalding temperature. Water temperatures above 55°C will cause severe scalding/burning and can kill a person.
Rada Maynell 15/3 Thermostatic valve
Temperature
- 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 ablution installations at between 60 to 65°C).
Flow Control
- The 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.
Connections
- Inlet and outlet connectors are 15 mm 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.
Pressures
- Minimum operating pressure: 0.1 bar.
- Maximum static pressure: 10 bar.
- Maximum pressure loss ratio*: 10:1 (in favour of either supply).
- Maximum hot water supply temperature: 85°C.
- Maximum cold water supply temperature: 25°C.
- Note! Both hot and cold pressure should be nominally equal.
The thermostatic valve can be installed before the inlet of a basin, scrub or slab sink to supply comfortable warm water without the risk of burning.
Mechanical hot and cold mixer
The EL-X60 is a small single basin mechanical hot and cold water mixer. It does not regulate the temperature as the GR-THERM or W-15/3. The mixing rate depends on the pressure and flow rate of the hot and cold inlets. This means you will have to regulate and set the flow rate and pressure manually in order to obtain the correct final outlet temperature. The mixing rate can also be adjusted on the device.
Hot & cold water mechanical mixer. The unit does not control the temperature.
Caleffi thermostatic mixing valves
The Caleffi thermostatic valve is made from DZR brass which makes it suitable for hospital use. Adjustment temperature between 30-65°C. Maximum static working pressure 14bar with maximum dynamic working pressure 5 bar. Maximum inlet temperature 85°C. Minimum flow rate 5 L/min.

Rada 215-T3 BC Thermostatic mixing valve for baby baths
The Rada 215-T3 BC is specifically designed for baby baths in clinics and hospitals. The unit should be connected to a hand shower or trigger hand shower. ½” thermostatic mixing valve incorporating Radatherm service-free cartridge, check valves and strainers. Housed within swivel elbows, featuring 15 mm compression connectors, which can be converted to ½” BSP union if required. Standard connections are hot (left), cold (right), top outlet. DZR brass nickel plated.
Pressures/Flow Rates
- Minimum dynamic supply pressure: 0.15 bar. Maximum dynamic supply pressure: 5 bar.
- Minimum flow rate:3 l/min at mid blend.
- Maximum flow rate: 35 l/min at mid blend (which equates to a maximum pressure loss of 1.8 bar).
- Maximum pressure loss ratio*: 10:1 (in favour of either supply). Maximum static pressure: 10 bar.
- Note! Both hot and cold pressure should be nominally equal.
Temperature Range
- Factory pre-set maximum outlet temperature: 43°C.
- Minimum temperature differential, blend to either supply: 12°C. Optimum thermostatic control range: 30 °C – 50 °C.
- Minimum cold water temperature: 1°C.
- Maximum hot water temperature: 85 °C.
- Note! The mixing valve can accept temporary temperature excursions above 85°C without damage, however, operation of the mixing valve at such elevated temperatures is not recommended. For reasons of general safety, hot water storage supply temperatures should ideally be maintained at between 60°C – 65°C where serving ablutionary applications.
Micro Thermostatic valve for single basins
The GroTherm Micro is a small thermostatic mixer designed for single hand wash basins only. It protects the user from scalding and reduces or mixes hot and cold water to a temperature between 15- 43°C. The GroTherm Micro is extremely easy to install with the two connecting braided pipes. The GroTherm Micro is ideal for hands free basin systems where a knee operated valve or floor operated valve are used. Since both these valves are not mixers (they do not mix hot and cold water), they require a thermostatic valve for warm water. Connection set consisting of: T-Unit, Union 3/8″, two outlets 3/8″ thread and union nuts. Flexible hoses optional.
Thermo scalding protection
- Temperature adjustment 15- 46 °C
- Thermal disinfection without re- adjustment of temperature
- Connection 3/8″ below with cap nut above 3/8″ male thread
- GROHE TurboStat® thermoelement
- Built- in non- return valves
- Dirt strainer
- Max. pressure differential 5:1
- Min. recommended pressure 1.0 bar
