A method for controlling a valve actuator, a valve actuator control device and a valve actuator assembly. The method includes the steps of providing a valve actuator control device, connecting the control device to a valve actuator with a signal transmitting wire, and supplying operating power to the valve actuator from the control device. The method further includes a step of transmitting control signals from the control device to the valve actuator via the signal transmitting wire in order to control the actuator. Hereby, configuration, control and maintenance of valve actuators are facilitated.

Method for controlling a valve actuator and a valve actuator control device

A flow controller for a heating system with a housing, which has an inlet connection for a heating medium, an outlet connection for the heating medium, and a preadjustment connection, with a rate regulating module, and with a handle, which acts together with a movably disposed structural element of the rate regulating module to preadjust the flow. To change the preadjustment of the flow via the handle, an effective cross section of a first flow-through opening for the heating medium can be adjusted and to regulate the preadjusted flow of the heating medium, a sleeve of the rate regulating module and a cup of the rate regulating module are disposed axially movable to one another. The inflow to the rate regulating module occurs on an outer side via the first flow-through opening which is provided on the sleeve and upstream of the second flow-through opening.

According to one embodiment of the invention, a control valve for regulating temperature comprises a conduit, a fluid limiter, a restoring actuator, an opening actuator, and a restoring actuator chamber. The conduit has an inlet, an outlet, and an opening between the inlet and the outlet. The inlet is operable to receive fluid into the conduit and the outlet is operable to dispense of fluid out of the conduit. The fluid limiter is operable to at least partially cover the opening and thereby resist flow of fluid through the opening. The restoring actuator is operable to provide a force that moves the fluid limiter toward the opening to resist flow of fluid through the opening. The opening actuator is operable to provide a second force that moves the fluid limiter away from the opening to allow the flow of fluid through the opening. The opening actuator is activated based on a temperature of fluid in the conduit. The restoring actuator chamber is disposed around the restoring actuator and has a passage in communication with fluid upstream of the opening.

Pressure relieved thermal regulator for air conditioning application

A three-way valve has its inlet fitting fixed to a housing and a pair of outlet fittings on opposite sides of the inlet fitting are formed on annular compartments which are rotatable on the housing to simplify orientation of the fittings for installation in pipe networks and the like.
