These pneumatic operated valves are developed and manufactured especially for the dosing of liquid and highly viscous products to different contiuous mixing units.

The dosing valve are opened by pilot pressure and closed by spring force. The looking piece is directly located on the outlet, so that the product not able to uncontrollably outflowed or blocking (strain hardening, crystallise) on the orifice outlet after the closing operation.

The design of the dosing valves are carry out corresponding to the specification, as well as the technological parameters (pressure, flow rate), product parameters (viscosity) and the constructional conditions (form / shape, dimensions) on the mounting place (static mixer, dynamic inline-mixer, extruder)
