The present invention relates to a manifold unit for supplying casting material in an injection moulding system for processing thermoplastic polymers via a hot runner system with at least one needle valve nozzle which can be sealed by a shut-off needle.Needle & Gauge Valves In this case, the shut-off needle can be moved by a hydraulic or pneumatic drive system. The needle valve nozzle has a first longitudinal axis and the drive system, which has a piston,Gate Valves has a second longitudinal axis, the first longitudinal axis being arranged parallel to and laterally offset from the second longitudinal axis.  BUTTERFLY VALVESA manifold unit for supplying casting material in an injection moulding system for processing thermoplastic materials via a hot runner system comprising at least one needle valve nozzle adapted to be sealed by a shut-off needle, wherein the shut-off needle can be moved by a hydraulic, electric, mechanical or pneumatic drive system, and wherein the needle valve nozzle has a first longitudinal axis, wherein the drive system, which has a piston, has a second longitudinal axis, and wherein the first longitudinal axis is arranged parallel to and laterally offset from the second longitudinal axis.
