For reversed flow direction

IMI Heimeier
Compare
​​​​​​​ Thermostatic valve body with and without presetting The thermostatic valve bodies for reversed flow direction can be used in two-pipe pump heating systems for interchangeable supply and return flow (hammering noises). The valve bodies can be mounted into the return flow connection of radiators in a raised position or tall radiators. This makes the thermostatic head more easily accessible.

Installation with interchanged supply and return pipe

Prevents hammering noises

V-exact II models with precision presetting

For exact hydraulic balancing

Eclipse models with automatic flow limitation

For automatic hydronic balancing

Valve body in gunmetal

Corrosion-resistant and safe

Technical description

Pressure class:

PN 10

Temperature:

Max. working temperature: 120°C, with protection cap or actuator 100°C.
Min. working temperature: -10°C.

Flow range Eclipse:

The flow can be pre-set within the range: 10-150 l/h.
Delivery setting 150 l/h.
(Max. nominal flow qmN at 10 kPa respecting EN 215: 110 l/h)

Differential pressure (ΔpV) Eclipse:

Max. differential pressure:
60 kPa (<30 dB(A))
Min. differential pressure:
10 – 100 l/h = 10 kPa
100 – 150 l/h = 15 kPa

The complete thermostatic insert can be replaced using the fitting tool without draining the system.
Spindle: Niro-steel spindle with double O-ring sealing. The outer O-ring can be replaced under pressure (Standard, V-exact II).

Surface treatment:

Valve body and fittings are nickel-plated.

Marking:

THE, flow direction arrow, DN and II+ Designation.
Without presetting: protection cap black, black stuffing box.
With presetting: protection cap white.
Eclipse: Orange protection cap.

Pipe connection:

The female-threaded version is designed for connection to threaded pipe, or in conjunction with compression fittings, to copper precision steel or multi-layer pipe (only DN 15).

Connection to thermostatic head and actuator:
