Vytautas engineering compatibility note (61170073E)
Verified mating components for Watts (61170073E) matched by connection standard (DN / thread / M30×1.5 / RA Click) and hydraulic compatibility.
Yes, this Watts unit (SKU 61170073E, category: Balansiniai ir reguliuojimo vožtuvai) is manufactured to European EN 12828 hydronic standards. Verify the connection thread or nominal size (e.g. DN15 1/2", DN20 3/4", M30×1.5 or Danfoss RA Click) – our engineering advisor Vytautas lists directly compatible mating components on this page.
Genuine Watts components use corrosion-resistant alloys (DZR brass, bronze or stainless steel) and calibrated flow paths, preventing valve sticking, water-hammer noise and premature seal leaks over 10+ heating seasons.
When installing Watts STATIC BAL VALVE W-STBV-16Q DN250 (61170073E, retail price 2098,72 €), check whether you need matching union tailpieces, Eurocone adapters, a mating thermostatic head or actuator. See the compatible parts section above.
Always observe the flow-direction arrow on the housing, depressurise the loop before fitting, and never apply hemp or tape onto flat union gaskets or O-ring cones.

Verification note: Solid-fuel boiler door aperture and flange dimensions vary by production year and kW rating – before ordering a door conversion kit or pellet burner, verify exact dimensions against the boiler passport or with a „Gilės inžinerija“ engineer (+370 693 97098).
Confirm that 61170073E connection matches the supply/return pipework and flow direction arrow.
Depressurise the heating circuit, fit the union tailpiece and tighten to factory torque.
Adjust the flow scale (Kvs / l/h) or controller setting according to room or boiler loop load.
Refill the loop, vent trapped air and verify leak-free operation under operating temperature.
Engineer pro tip: When installing Watts (61170073E), never wind hemp onto flat gasket seats or Eurocone O-ring cones – seal only tapered pipe threads.
