Introduction
The extensive use of WAM’s proprietary SINT engineering polymer, combined with an innovative geometric design, makes this Multi-Choke Valve a highly effective solution for controlling the flow of powders, flakes, or granular materials in both gravity and conveying applications. A food-grade version, compliant with Regulation (EC) No. 1935/2004, meets the stringent demands of high-end industrial sectors.
High abrasion resistance thanks to replaceable SINT gasket and choke paddles
Quick fitting thanks to WAM and CEMA flange compatibility
One actuator for controlling three choke paddles with different opening angles
Spécificités techniques
Description
The VPM Multi-Choke Valve consists of a metal frame, three SINT engineering polymer-coated choke paddles, an integral SINT engineering polymer gasket, a splined actuator drive shaft and guarded power transmission on both frame sides.
Fonction
VPM Multi-Choke Valves are designed to intercept the flow of dry powders or granular materials, whether gravity-fed or conveyed. They can be installed below the outlets of hoppers, bins, or FIBCs, as well as at the inlets and outlets of mechanical conveyors, and above the inlets or outlets of belt conveyors.
Thanks to their specially engineered geometry and a range of choke design options, VPM Multi-Choke Valves are suitable for use across virtually all industries, including food processing.
Their efficient performance, combined with the use of high-grade engineering materials, makes them a cost-effective solution wherever contamination or material pollution must be avoided during processing.
Caractéristiques
- PATENTED for technical design
- Minimum overall height
- Compatible with WAM and CEMA flanges
- Safe sealing with no additional measures due to the all-round dustproof seal lips integrated into the polymer coating
- Highly abrasion-resistant, wear compensating, replaceable gasket in SINT engineering polymer for standard or food-grade applications
- Food-grade version compliant with Regulation (EC) 1935/2004
- Interchangeable actuators: manual, pneumatic
- Possibility of adjusting the choke opening angle to create a material feeding effect
- Standard sizes: 300 ~ 400mm (12” ~ 16”)
Avantages
- No contamination due to choke paddles and valve frame lined with SINT engineering polymer
- Dust, pellet and granule-proof thanks to special component geometry
- Highly abrasion-resistant due to replaceable SINT gasket
- No downtime for gasket adjustment
- Easy integration into the process thanks to light weight and eased handling
