Herz T0190127 elektrinė pavara
- Purpose: automatic control of Herz control valves
- Compatibility: Herz control valve family (specific model list — in Herz documentation)
- Application: heat substations, DHW, cooling systems
Where T0190127 is used
Electric actuators for Herz control valves are used at automatic control points in heating/cooling systems: return temperature control, mixing valve control, flow control in heat substations. The actuator converts the electrical signal from a controller (Ouman, Danfoss ECL, Siemens RVD) into mechanical valve stem movement — the valve opens or closes flow per the control command.

Frequently asked questions
Can it be used with other manufacturers' valves?
Herz T0190127 is designed for Herz valves. Fitting to another manufacturer's valve is possible only if stem geometry and Kvs match — rarely in practice. Choose the matching-brand actuator (Belimo, Siemens, Sauter, Honeywell) for those valve families.
How to match the control signal with the controller?
Depends on the T0190127 variant. A 3-point actuator wires to three contacts (open / close / common). A 0-10V modulating actuator uses three wires (+24V, GND, 0-10V signal). Verify controller output compatibility with actuator input before installation.
Is manual override required?
Recommended. Manual override allows service, system testing, or valve operation when the controller fails. Herz electric actuators typically feature a manual button or wrench — verify against the specific T0190127 variant.
How to diagnose actuator failure?
Symptoms: (1) no response to control signal — check supply and signal wiring, (2) actuator moves but the valve does not — check the mechanical link between actuator and valve stem, (3) unstable regulation — check PID settings in the controller and actuator stroke speed.
