Multi-Choke Valve VPM

Multi-Choke Valve VPM: Precise Dosing, Zero Waste, Maximum Product Care

The Multi-Choke Valve VPM is designed to intercept, dose and discharge powdery or
granular materials in gravity-fed lines and on mechanical conveyors.
By minimising residue between the valve and the downstream equipment, the VPM Valve
enhances hygiene, process efficiency and repeatability. It can be installed beneath hoppers,
silos and big-bag dischargers, at inlet or outlet points of screw conveyors, or above belt
conveyors.
How it works
The die-cast aluminium body houses three polymer-coated blades—one driving and two
driven—together with an integral SINT® Engineering Polymer gasket that ensures tight
material containment without the need for additional flange gaskets. Protective covers on
both sides safeguard the mechanism and drive unit.
The profile and geometry of the blades enable controlled openings and smooth discharge,
even with hygroscopic or poorly flowing materials. A vibrator kit for the blade shaft is
available to further improve material flow.
Why the VPM Valve stands out
 Reduced residue: fewer build-ups and quick material changeovers.
 Superior sealing: the integral SINT® Engineering Polymer gasket reduces potential
contaminations.
 Seamless integration: WAM® and CEMA compatibility allows quick installation in
existing layouts.
 Versatility with “difficult” materials: blades and optional vibrators facilitate flow
when handling crust-forming or hygroscopic products.
 Simplified maintenance: modular, replaceable components and easy access.
Fields of application
Feed and food, chemicals, plastics, drymix/building materials, detergents/cosmetics, glass
and flour – wherever reliable interception and contamination prevention are required.
