Rimor manufactures industrial round valves in standard models from 200 mm diameter to 3500 mm diameter.

Rimor technical department is available to customers for the sizing and selection of industrial valve materials with specific applications.

Industrial round valves, depending on the size, pressure and temperature of use, the movement of the shaft can be manufactured in various ways, for example:

• secured on one side by supports and lubricated bearings and on the other by precision bushing
• supports and lubricated bearings at both ends of the shaft

The compartmentalisation (and/or regulation) disc of industrial round valves is appropriately dimensioned according to the pressures and temperatures of use.

The compartmentalisation disc of industrial round valves can be single or double blade.

Just as it is done for industrial round valves, square valves are also designed taking into account the pressures and temperatures of use.

Rimor industrial square valves do not have a standard dimension. Rimor’s technical department analyzes each request individually.

Rimor industrial square valves are divided into two main categories with the following features:

Simple industrial square valves:

• usage temperature < 350°C
• usage pressure < 2000 Pa

Heavy industrial square valves

• usage temperature < 1000 °C
• usage pressure <2000 Pa

Depending on the dimensions of the industrial square valves, floe regulation is obtained with a series of winglets whose movement is guaranteed by shafts on bearings and leverages. The winglets can be parallel or counterposed.

The guillotine valve is used for all those applications where there must be no impediment to the passage of the flow (with the valve open) reducing the load losses, a detail that cannot be achieved with a butterfly valve.

The guillotine valve is not used for flow regulation but for compartmentalization.

All Rimor’s guillotine valves are made with the supporting structure in carpentry that changes according to use, the temperature of use and the fluid.

The Rimor builds unidirectional guillotine valves and guillotine valves with through blade with manual controls with handwheel, lever, double-acting or single-acting pneumatic controls, hydraulic controls and electric controls.

Rimor also builds guillotine valves to intercept dust and granules – usually placed under silos and hoppers – with the sliding of the bulkhead by means of a single series of rolling bearings or double series of rolling bearings or sliding guides in self-lubricating material.

Radial vane damper valves are widely used where a flow rate adjustment or a partialization of air flows is required. Radial vane damper regulation valves are available with diameters starting from 250 mm up to 3000 mm.

For larger dimensions, consult our technical department.

They can be installed in all those systems where a regulation of the flow rate is required in the suction, ventilation and filtration systems, on the suction inlets of the fans and so on.

The regulation of the flow rate in the radial vane damper valves is obtained by means of lens (blades) operated simultaneously by external levers, whose rotation is ensured by bushings and / or supports on lubricated bearings

Depending on the size, radial vane dampers valve can be equipped with a central ogive.

Rimor manufactures check valves for installation in ventilation systems. An important feature of Rimor check valves is the complete disappearance of the shutter.

Like all Rimor products, the check valves are sized and calculated with finite element software to obtain the minimum losses in the actuation of the shutter and that resist the counter pressure of the air flow.

The check valves can be used wherever there is a need to prevent the return flow of air by allowing the passage of air in only one direction.

All Rimor check valves are made with the supporting structure in carpentry which, depending on the use, can be built in the most appropriate materials.

Rimor manufactures diverter valves (three-way valve) in square – rectangular – circular sections.

With the use of the diverter valve, a flow can be completely diverted or modulated.

The diverter valve is often a preferred solution to the use of two single independent butterfly valves for ease of flow management, compactness of the system and the use of a single drive for handling.

The Rimor diverter valve is classified and built based on the temperatures, flow rates and pressure of use.

Rimor’s technical department is available to advise and evaluate the possibility of special executions.

Sealing is a very important feature of air valves as it allows you to isolate the upstream and downstream environments of the valve itself and not have any leaks to the outside.

Throught CFD simulations, Rimor is able to develop valves in compliance with the main sealing classes.

Upstream-downstream sealing

For the movement of the valves there are different solutions: manual, electric, pneumatic and with motor reducer. Based on the different customer requests we can choose the most suitable integration solution on the valve.

The handling system can be equipped with the positioner, a tool that allows precise adjustment of the air flow on the system.

Manual

The manual handling system is implemented through the aid of a lever managed by an operator with the possibility, thanks to a screw locking system, to fix the sail in the position desired by the user.

Electrical

The electric movement is by rotary, with or without positioner which involves having two types of valves which can therefore be modulating or on-off respectively.

Pneumatic

This type of movement can be of a rotary or linear type and in both cases it can be with or without a positioner, therefore consequently modulating or on-off respectively.

The position of the switches can be easily changed thanks to the presence of cams with fine-pitch knurling, which can be adjusted manually and independently without the need for tools.

Compact Design

The boxes have a compact design and small dimensions, minimizing the overall dimensions of the valve + box assembly.

Simplicity of connection

The BE45 is equipped with an inclined 8-terminal terminal block to facilitate wiring and with 2 M20x1.5 inputs (1/2 ”NPT on request).

Three-dimensional indicator

The three-dimensional OPEN / CLOSED indicator standard on the BE45 series allows a clear reading of the current state of the valve.

Mounting brackets

Supplied as standard, the stainless steel mounting bracket fits NAMUR holes 80mm by 30mm and pinion height H30mm. The bracket allows coupling with actuators having pinions protruding H 20 mm thanks to the use of a technopolymer extension.

The electric actuators are suitable for the automation of butterfly valves for the industrial sector. The use of latest generation electronic components, associated with mechanics that are the result of careful research and design, guarantees the product’s high performance and reliability over time.

The range is made with the following features:
