A valve arrangement has two main valves which are each preloaded by a spring device into a first switching position, and which can each be switched into a second switching position by means of an assigned pilot valve. The pilot medium required for switching is provided with a pilot pressure at a pilot connection of each pilot valve. The main valves are each equipped with a working valve section each of which are fluidically connected to one another. In addition, each main valve contains a monitoring valve section. The monitoring valve sections are designed to provide the venting of at least one pilot connection when the two main valves are in different switching positions. This allows a fluid-actuated actuator to be controlled in accordance with high safety standards.

The invention discloses a metal cutting machine with anti-cutting hands, which includes a cutting base. The cutting base is provided with a main power cavity, and the main power cavity is provided with a power device. The power device can provide a device for the device. Power. The invention has a simple structure, convenient maintenance, and easy use. The device can automatically adjust the cutting position, and at the same time, it can automatically monitor the living body during the metal cutting process. When the human body enters the danger zone, it can automatically start the built-in The emergency clamping device clamps the blade, so that the blade stops rotating, preventing the blade from cutting the human body and causing injury to the human body, thereby greatly improving the safety during production and preventing accidental injury.

Safety systems requiring intentional function activation and material testing systems including safety systems requiring intentional function activation are disclosed. An example material testing system includes: an actuator configured to control an operator-accessible component of the material testing system; an operator interface comprising a plurality of inputs; and one or more processors configured to: control the actuator based on at least one of a material testing process or an input from the operator interface; and require two or more inputs to be received within a predetermined threshold time to permit at least one operation of the actuator.

Apparatuses for pressing and heating a material and associated methods are disclosed herein. An apparatus of the present technology includes a housing, a pressure component positioned in the housing, a linkage component coupled to the pressure component, a first heating component coupled to the linkage component, and a second heating component positioned adjacent to the first heating component. The linkage component is movable between a first position and a second position. When the linkage component is at the first position, the linkage component is positioned at a first level. When the linkage component is at the second position, the linkage component is positioned at a second level and the linkage component holds the first heating component stationary relative to the second heating component.
