Extremely high flow rates (20 L/min at only 2 metre head) makes the valve (TV20) suitable for both high and low pressure installations.
Valve can be installed in any orientation
Failsafe shutdown - In the event of failure of hot or cold supplies.
Tamperproof cap - less call outs for readjustment by plumber (TV20TP)
Forged, high quality, corrosion resistant DR brass body.
Machined, assembled and 100% tested in NZ.
Advanced temperature control - ideal for direct connection to a sanitary fixture e.g. hand basin (TV15P)

Factory set to give 55°C outlet. Can be adjusted from 35°C to 60°C.
Maximum inlet temperature 99°C
Stored water temperature must be at least 10°C above the Tempering valve setting and over 60°C (G12)
Inlet Pressures:TV15,TV15P 30 to 1000 kPa (3m head)TV20,TV20D,TV20TP 20 to 1000 kPa (2m head)
Flow Rates:TV15 20 L/min at 30 kPa inlet pressureTV15P 9 L/min at 30 kPa inlet pressreTV20,TV20D,TV20TP 20 L/min at 20 kPa inlet pressure
Operating Pressure:Balanced hot and cold pressure. For unequal water pressure of up to 5:1 (Cold:Hot), non-return must be fitted to hot inlet.

Refer Technical Section for installation guide
Valve must be fitted by a qualified plumber
Installation must comply with local authority requirements
Valve may be installed in any orientation
Flush pipes prior to fitting
Valve must be protected by line strainer
Non-return vales are required at hot and cold inlets in Ring Main Installations
Connections are H (hot inlet), C (cold inlet) and OUT (mixed temperature outlet)
Do not apply heat near the valve during installation - this may damage the mechanism.
Do NOT install valve directly onto outlet of cylinder
1 m MIN copper pipe length from cylinder to tempering valve, THIS IS MANDATORY REQUIREMENT OF G12.
