Key Information
- Feeds high volumes of powder at a controlled rate.
- cGMP design
- Allows for accurate dosing of material. Rotovalve Heavy can be supplied with accompanying control panel to allow user to regulate and alter speed of rotation, set the number of rotations and if required to work with load cells for high accuracy applications.
- All parts can be easily dismantled for ease of cleaning.
- All contact parts are 316L and non-metallic parts are FDA compliant. Full documentation is provided with each valve.
Technical Description
Using an electric motor rotating the rotor 360°, the heavy duty rotary valve is designed for applications where greater control and accuracy of dosing is required. The valve is of fully stainless steel construction with ‘labyrinth’ design where there is no sealing gasket between the two faces. This design gives the user several benefits;
> In applications where many different products are dosed on the same day, the valve can be quickly disassembled and cleaned between each batch. Having no gasket makes for easier cleaning and gives the user more confidence that there is no powder residue on the gasket.
> There is no metal-to-metal contact preventing ingress of metal particles into the product and mainly preventing sparking – a must for ATEX zones.
> No gasket means no replacing the gasket reducing future costs and downtime.
> No gasket prevents and possible ingress of gasket material into the product.
Generally the Rotovalve Heavy will be found installed above mixers, tablet presses and packing lines.

Customised Valves
We understand that standard ‘off-the-shelf’ valves will not always be suitable for your application, and that’s why we offer bespoke solutions for our customers.
Flexible Butterfly Valve
The flexivalve is inherently the same as the butterfly valve, but instead of a stainless steel vane, the flexivalve is fitted with a silicone vane.
Rotary Crushing Valve
The Rotocrusher is a single-roll lump breaker (rotary crushing valve type).
Rotary Dosing Valve
The Rotodoser is designed for applications where high accuracy and fine dosing are required.
Rotary Valve Light-Duty
The light-duty rotary valve is suitable for the pharmaceutical, chemical and food industry.
Rotary Valve Plus
The Rotovalve Plus is designed to aid the feeding and volumetric dosing of bulk solid products.
Sanitary Butterfly Valve
Butterfly valves are one of the most common valves seen in process applications.
Split Butterfly Valve
The Sterisplit is a split butterfly valve or high-regulation valve intended to move powders safely in sterile or potentially dangerous applications.
