Description

Application

Where water temperature control must be precise or water is required to be at safe skin contact temperature (45°C) e.g. childhood centre, schools, old peoples homes, hospitals and institutions for people with psychiatric or physical disabilities.

  • Fail safe shut down, controls temperature, factory set to 45°C.
  • Outlet temperature adjustable 35 – 60°C.
  • High flow rate, 40 L/min at 500 kPa.
  • Forged, high quality and corrosion resistant, DR brass body, nickel plated.
  • Integral no-returns means valve is ideal in ring main installations.
  • TMV 20 has internal chamfer to suit compression fittings – no union required.
  • TMV 20BV comes with right angle ball valves for easy testing, maintenance or replacement.
  • TMV 20 & TMV 20BV both have integral, 250 micron/60 mesh filters to ensure no debris enters the valve.
