Rotary valve of horizontal passage

VRH

Rotary valves of horizontal passage are used to introduce products (powders or granulates) into a high pressure pneumatic or vacuum conveying line (0.2 to 1.0 bar), promoting system tightness and dosing.

Manufacturing 
material:
Nodular cast iron / SAE 1020
Cast stainless steel / INOX 304
Pressure diferential:
1 bar
Volumetric flow rate:
2,5 ~ 55L per revolution
Description

They are composed of a housing, covers and rotor, their internal clearances are machined with high precision and a special sealing system that guarantees tightness and continuous operation without leaks in the system both in its bearings and in the input and output passage.

We have differentiated standardized designs that can meet different needs for products that are more difficult to flow, hygroscopic, abrasive, among other cases, which is why specific lines were created for each particularity.

With an almost identical design to the VRV model, its main distinction lies in its covers with direct passage entry and exit for installation in pneumatic transport lines, mainly used at the beginning of the lines.

Operation principle

At least two compartments at a time of the continuously rotating rotor are filled with material through the inlet at the top of the rotary valve, the rotor is divided into multiple internal chambers where the product is stored and is continuously dosed in the direction of rotation and exit of the equipment.
 

Main Features

A concept for every need

With the variety of optionals, it is possible to meet a wide range of needs, whether for more abrasive, hygroscopic and difficult-to-flow products, or for easy-flow products.

In the smallest details

Well-sized shafts eliminate rotor deflection, reduce wear at the ends and prevent leaks in the bearing seal.

High precision machining

Valve internal clearances as required during operation eliminate axial movements and extend maintenance cycles.

The right rotor for every situation

Our experience in rotary valves allows us to select the best option suited to your reality.

  

Application

They can be applied to mechanical transport lines for dosing products, ensuring continuous and uninterrupted flow in the operation of the plant in which they were intended, widely applied to different types of products, normally in powder or granular form.

Dosage: allows flow control (volumetric) of the transported product in a way that meets the projected requirement.

Ecluse: allows the sealing of a high pressure system, restricting the excessive passage of air and releasing the passage of solids in the opposite direction to the pressure exerted by the line return.
