Abstract: Modular device and method for carrying out experiments in parallel on process substances to develop technical methods, comprising at least a multiplicity of individual reactors which are controllable independently of one another said reactors being comprised of pressure-tight chambers having separable sample vessels, and optionally, stirring devices, heating instruments, cooling instruments, or both, a monitoring unit for monitoring or controlling at least the pressure and the temperature in the individual reactors, pressure-tight lids having independent feed lines and optionally independent discharge lines for individual process substances; a plurality of the lids being simultaneously sealable upon the rectors by a common sealing means (11).

Abstract: A modular, actuated valve controlled by means of pressure fluids comprising a head plate mounted on a housing plate mounted on a base plate, held together by screws, having a piston with attached valve spindle and a pressure relief space provided between the flow passage 28, 29 and the piston.
