Elektrogas - SR, SL, ST - Solenoid Actuators

Solenoid actuators SR/SL/ST are designed to operate VF and VFH butterfly valves, used in twostage control of gas flow and air flow in combustion processes.

Elektrogas - SR, SL, ST - Solenoid Actuators

Features


> Available with fast opening and fast closing (<1s), with slow opening (3 4s) and fast closing or with slow opening and slow closing (3-4s)
> Equipped with two regulating screws for minimum and maximum flowrate adjustment.

> Provided with valve disc position indicator.
> Suitable for intermittent operation and large number of operating cycles.
> Its sturdy and functional design allows a fast and easy installation, and it is practically free of maintenance.

> All components are designed to withstand any mechanical, chemical, thermal condition occurring during typical service. Effective impregnation and surface treatments have been used to improve mechanical sturdiness, sealing and resistance to corrosion of the components.
