FLOMIX Lead Free Thermostatic Mixing Valves

Gentec FLOMIX thermostatic mixing valves are NSW Health Approved zone-level TMVs manufactured from Lead-Free DZR Brass with a chrome-plated finish, designed for recessed wall-cavity installation in Australian hospitals, aged care facilities and institutional buildings. Unlike point-of-use thermostatic mixing taps, FLOMIX valves condition the mixed water temperature for a zone or circuit of multiple outlets – satisfying NSW Health PD2015_012 requirements and AS/NZS 3500.4:2003. Six models cover the full installation scenario matrix: with or without cold water bypass, with recessed stainless steel enclosure, and with strainers, non-return valves and isolation valves included. For individual point-of-use thermostatic mixing taps, see TEMPSET Lead-Free Brass Tapware.

Why specifiers choose Gentec

  • NSW Health Approved status on all 6 FLOMIX models: required by NSW Health policy PD2015_012 for TMVs installed in NSW public hospital and healthcare premises – not all TMVs on the Australian market carry this approval.
  • Lead-Free DZR Brass body: complying with AS 2345 for reliable performance in demanding plumbing applications.
  • Chrome-plated finish on valve body and enclosure components: compatible with hospital-grade disinfectants used across NSW Health and private hospital networks.
  • Cold water bypass option (MVLF60154, MVLF60154H): provides a fail-safe cold water delivery path if the hot water supply fails.
  • Stainless steel recessed enclosure with lockable lid: tamper-resistant, concealed installation with authorised-access-only service points.
  • Two lid types – hinged (H models) and recessed lockable (non-H models): allows specifier flexibility based on wall-cavity depth and maintenance access requirements.
  • Copper tails pre-fitted (60153/60154 series): simplifies connection to copper pipework distribution systems standard in Australian hospital hot water infrastructure.

Which tapware is right for my project?

Choose FLOMIX – Your project requires a zone-level thermostatic mixing valve with NSW Health Approval, installed in a wall cavity with a stainless steel recessed enclosure and lockable lid – cold water bypass, copper tails, strainers or isolation valves pre-configured.

Choose TEMPSET instead – Your project requires a visible, lever-operated thermostatic mixing tap at an individual basin, shower or hob position – not a zone valve.

How to Choose

Determine whether a cold water bypass is required by the engineering design:  If yes, specify MVLF60154 or MVLF60154H. If not, specify MVLF60153/60153H or MVLF5015/6015.

Select enclosure type:  stainless steel recessed lockable enclosure models (MVLF60153 series) for concealed installation. MVLF5015 and MVLF6015 are supplied without a separate enclosure.

Select lid type: hinged lid (H models) if maintenance access and swing clearance are available; recessed lockable lid (non-H models) where space is constrained.

Confirm accessory inclusion: MVLF5015 includes strainers and non-return valves; MVLF6015 adds isolation valves; MVLF60153/60154 series includes copper tails.

Download the FLOMIX datasheet: confirm WELS registration, Lead-Free WaterMark licence number, and flow rate before including in the hydraulic specification schedule.

Thermostatic Mixing Valve Applications by Industry:

Gentec FLOMIX thermostatic mixing valves are designed to support the requirements and design principles outlined in the Australasian Health Facility Guidelines (AusHFG), providing controlled water temperatures and serviceable TMV solutions for healthcare environments.

NSW Public Hospitals – Zone hot water TMV at riser or circuit level | MVLF60154 or MVLF60154H

Aged Care Facilities – Hot water zone mixing for ensuite circuits | MVLF60153 or MVLF60153H

Private Hospitals – Zone TMV for patient ward hot water circuits | MVLF6015

Institutional Buildings – University, TAFE, government building hot water | MVLF5015 or MVLF6015

Common Mistakes When Specifying

  • Specifying a TMV without NSW Health Approval in an NSW public hospital: NSW Health policy PD2015_012 mandates approved TMVs.
  • Confusing FLOMIX (zone TMV) with TEMPSET (point-of-use tap): both are typically required in a healthcare hot water system, but they are not substitutes.
  • Selecting the wrong lid type for the wall-cavity depth: hinged-lid models require swing clearance not available in all shallow wall cavities.
  • Omitting cold water bypass in NSW Health facilities that require it: check the current version of NSW Health PD2015_012.
  • Assuming lead-free and NSW Health Approved are equivalent certifications: they are separate – FLOMIX holds both, but not all products on the market do.

 

FLOMIX Lead Free Thermostatic Mixing Valves FAQ's

What does NSW Health Approved mean for a thermostatic mixing valve?

NSW Health Approved means a thermostatic mixing valve has been assessed against NSW Health engineering policy PD2015_012, which governs TMV selection, installation, commissioning and maintenance in NSW public hospital and healthcare premises.

What is the difference between MVLF60153 and MVLF60154?

The MVLF60154 includes a cold water bypass in addition to the stainless steel recessed enclosure and copper tails; the MVLF60153 does not have a cold water bypass.

What is the difference between hinged and recessed lockable lid FLOMIX models?

The H-suffix models have a hinged lockable lid that swings open on a hinge for service access. The non-H models have a recessed lockable lid that is removed completely for access. The choice depends on wall-cavity depth and maintenance team preference.

Does FLOMIX require periodic calibration?

Yes. Under AS 4032.1 and AS/NZS 3500.4, thermostatic mixing valves must be periodically tested and calibrated to confirm the mixed water temperature remains within ±2°C of set point and the fail-safe thermal shutdown operates correctly.

Does FLOMIX hold both Lead-Free WaterMark and NSW Health Approval?

Yes, the Gentec FLOMIX range is described as both Lead-Free DZR Brass and NSW Health Approved on all 6 listed models. Both certifications are distinct: Lead-Free WaterMark certifies compliance with AS/NZS 4020 drinking water contact material standards under NCC 2022; NSW Health Approval certifies suitability for NSW public hospital and healthcare premises under PD2015_012. Confirm both certification numbers from the datasheet before specification. 

What accessories are pre-fitted to FLOMIX valves?

MVLF5015 includes strainers and non-return valves. MVLF6015 includes strainers, isolation valves and non-return valves. The MVLF60153/60153H/60154/60154H models include copper tails and a stainless steel recessed enclosure with lockable lid; the MVLF60154 series also includes cold water bypass. Confirm the exact accessory list against the individual product datasheet before finalising a hydraulic specification, as configurations can be updated between model revisions.

Are FLOMIX valves suitable for aged care facilities outside NSW?

Yes. FLOMIX valves meet AS/NZS 3500.4, AS 4032.1 and carry Lead-Free construction applicable across all Australian states and territories under NCC 2022. NSW Health Approval provides additional assurance but is not a limitation on use elsewhere – FLOMIX can be specified in Victoria, Queensland, Western Australia, South Australia, the ACT, NT and Tasmania in line with those states’ plumbing codes.  

Can FLOMIX replace a TEMPSET point-of-use tap?

No. FLOMIX is a zone-level thermostatic mixing valve for concealed wall-cavity installation, conditioning water for a circuit of multiple outlets. TEMPSET is a point-of-use tap with an integrated thermostatic cartridge at an individual basin or shower. In a correctly designed healthcare hot water system, both are typically used together – FLOMIX at the zone level, C at each point of use.
