Optimize your processes with CO.RA.® valve flap systems
The GMP-compliant flap systems from CO.RA.® are used in the bulk solids sector for flow control. They are convincing in terms of cost-effectiveness, are characterized by short assembly times, can be dismantled without tools and are therefore easy to clean.
The components of the SOLE VALVE, TABLET VALVE and ROTARY VALVE flap systems are interchangeable without having to replace the entire unit. The inner part is replaced, the outer body remains the same. Operation is simple, reliable and safe.
Since its foundation, CO.RA.® has been dedicated to innovative developments, patenting and the manufacture of components for the pharmaceutical and chemical industries worldwide. CO.RA.® is a leader in the development of new valve and flap systems.
CO.RA.® has been involved in the controlled feeding of systems and dosing of solids in pharmaceutical processes since the 1980s. All products are subject to the strict hygienic requirements of the pharmaceutical industry.
The valve flaps SOLE VALVE®, ROTARY VALVE® and TABLET VALVE® were developed for the flow control of bulk goods (capsules, pills and tablets). SOLVE VALVE® was already established on the market in the 1980s in response to the needs of pharmaceutical customers.
Since the completion of its own sterile room in the 1990s, CO.RA.® has concentrated mainly on the development of filling systems that enable the processing of high containment substances.
CO.RA.® invests resources tirelessly every year in the research and development of products and has been the only company in Italy capable of producing silicone seals under sterile conditions for a year now.
BOLZ INTEC has been the official distributor for Germany since November 2009.

The DOUBLE VALVE® flap valve serves as an interface to an automatically programmable weighing system.
The valve is fixed under the machine with a clamp and acts as an outlet opening. The valve controls the discharge of 95% of the weight by automatically opening the flap using a pneumatic drive.
It is operated by 2 double-acting drives made of anodized aluminium: 90° for the flap and 180° for the rotor.
Housing: AISI 316 L stainless steel
Seal: Silicone in accordance with FDA standard 177.260
The rotor for fine dosing can be customized with the number and volume of the piston pump according to customer requirements.

Transfer systems for the pharmaceutical industry
Transport / transfer systems for solids and liquids for use in the pharmaceutical industry. Particularly environmentally friendly, product-friendly and health and safety compliant.
BOLZ INTEC develops manually operated systems directly for operational practice in close cooperation with leading European pharmaceutical companies (R&D kilolab level). Each EPTS is custom-made and therefore always state-of-the-art.
EPTS (Emission Free Powder Transport System)
for the closed transport of toxic media within a plant, e.g. from the weighing room to the reactor, with guaranteed emission-free product transport.
The system:
The EPTS consists of a container equipped with two flap valves attached to both openings. A funnel for filling and a CiP chamber for cleaning the entire system can be attached to the valve on the upper part of the container. The flap valve at the outlet of the transfer container is fitted with the respective connection of the reactor to be filled.
The active "clean-in-place system" ensures 100% emptying and enables the entire system to be cleaned without emissions. This ensures absolute employee and product protection.
The process flow:
Filling:
The filling funnel is flange-mounted on the upper part of the EPTS. The medium is then filled under a suction unit and weighed in. After filling, the flap valve is closed and the CiP chamber is refitted so that the EPTS can be moved to the reactor.
Problem-free filling:
When filled, the EPTS is docked onto the respective reactor, the powder is introduced into the subsequent process by opening the flap valve and applying a vacuum to the reactor. The "clean-in-place system" attached to the transfer system ensures that the entire system is subsequently cleaned without emissions. This ensures absolute employee and product protection.
As the EPTS and the reactor have the same specifications in terms of pressure and vacuum, necessary functions such as inertization and charging can be carried out under vacuum.
Technical features:
- Volume: 200 ml - 300 liters
- Pressure: Full vacuum / +1.5 bar
- Surface finish process side: RA'0.25μm Surface finish all others: RA ' 0.8 μm
both electropolished - Materials/process side: 1.4435 AISI 316L Hastelloy C 22 (optional)
- All others: 1.4301 AISI 304
- Seals: EPDM and/or PTFE (FDA-compliant)

Warum sich Kunden weltweit für unsere Sonderkonstruktionen aus Edelstahl entscheiden
High efficiency, low costs & great economy
Time savings in production
The use of stainless steel containers with optimized surfaces leads to significant time savings in the production process. By minimizing the build-up of materials, cleaning and maintenance times can be drastically reduced. This enables the containers to be reused more quickly and increases the overall efficiency of the production lines. In a production-intensive environment where time equals money, this time saving represents a significant economic advantage.
Reduced risk of production downtime
The reproducible quality of the stainless steel surfaces and the reduced number of defects minimize the risk of production downtime due to surface problems. This can lead to higher overall productivity and less downtime.
Reduction of production losses
Optimizing the container surfaces also minimizes the amount of product loss. Reduced adhesion means that more of the material produced is available for its intended use and does not end up as waste. This is a particularly important factor in industries where high-quality or very expensive materials are processed.
Improvement of product quality & product safety
Contamination-free production results in a higher quality end product. This is crucial in industries with strict quality and purity requirements, such as pharmaceuticals and food production, where purity and safety are top priorities. The use of optimized stainless steel containers can therefore also lead to improved brand image and customer satisfaction. We ensure the quality of our containers through our QM officer and stringent production processes. You will receive the corresponding documentation for each of our stainless steel drums.
Cost reduction through efficient cleaning & barrel maintenance
In addition to saving time, optimized surfaces also lead to a reduction in the costs of cleaning processes. Less build-up means less need for cleaning agents, water and energy. There is also less wear and tear on the containers themselves, which increases their service life and reduces the need for new purchases. In the long term, these savings in operating costs can make a significant difference to a company's profitability.
Longer container service life & positive eco-balance
The improved corrosion protection provided by the electropolishing process helps to extend the service life of stainless steel containers. Customers can thus reduce their costs for replacement investments and maintenance.
Customers from these industries increase their production efficiency with special stainless steel constructions from BOLZ INTEC
