Abstract
A valve range is suggested suitable for use in connection with the control of fluid operated equipment. It possesses a fluid manifold, which is able to be fitted with pneumatic valves, which are operated via a signal manifold electrically. The valve range is so designed that it is suitable for the combined operation or control both of pneumatic valves and also of hydraulic valves. For the control of hydraulic valves it is provided with at least one control connection, from which the respective control signals may be taken. It is in this manner that, starting with a central valve range both pneumatic and also hydraulic valves may be operated and controlled in a comparatively simple fashion.
Claims14
A valve range for use in connection with the control of fluid-operated devices, comprising:
- a fluid manifold provided with internal fluid ducts, at least one of said ducts being a supply duct and at least another of said ducts being a spent air venting duct;
- electrically operated pneumatic valves, said pneumatic valves communicating with said fluid ducts, said fluid manifold being fitted with said pneumatic valves;
- valve drives for said electrically operated pneumatic valves;
- a signal manifold, said signal manifold providing first electrical signals for the operation of said pneumatic valves;
- an electrical conductor arrangement provided along said fluid manifold, said electrical conductor arrangement being connected to said valve drives for said pneumatic valves, said conductor arrangement being further connected to said signal manifold for transmission of said first electrical signals for the operation of said pneumatic valves;
- an electrically operated hydraulic valve;
- an electrically operable drive for said hydraulic valve;
- a control connection for connection with said electrically operable drive of said hydraulic valve, said control connection being electrically connected to said signal manifold, said signal manifold providing at least a second electrical signal through said control connection for operation of said hydraulic valve;
- a control unit associated with said signal manifold, said control unit containing a program that controls said first electrical signals and said second electrical signal for control of said pneumatic valves and said hydraulic valve, respectively.
