How a pinch valve works for a pipe system

Closed or open for a pipeline. When vacuum conveying from multiple locations to the same delivery point, we can control which pipe or hose we need to open or close. Pinch valves are a reliable and low-maintenance solution for controlling powders, granules and other bulk materials. The valve regulates or shuts off the product flow by squeezing a flexible sleeve, so that the product only comes into contact with the valve's inner sleeve. This reduces wear and tear, minimises the risk of blockages and ensures tight and efficient flow control, even in demanding applications.

Why use pinch valves?

Pinch valves are developed for demanding powder applications where operational reliability and tight shut-off are crucial. Unlike traditional valve types, the product only comes into contact with a flexible sleeve, which reduces wear, product accumulation and the risk of leakage. The result is a more reliable transport system with less maintenance and higher uptime.

Good for Diverter line funktion

Can be used to open or close specific conveying routes

Lower risk of product build-up

When the valve is open, it has almost full, free flow without pockets or dead zones.

Hygienic solution

Food-grade versions with Tri-Clamp and 316L stainless steel 

Suitable for ATEX areas

Can be easily supplied ATEX-approved with pneumatically operated valves

We help you choose the right pinch valve for the job, based on your requirements for hygiene, operation and production.

Examples of pipe components

We work with various manufacturers within pipe components. We have experience that means we know what challenges the manufacturers face and which factories have the best components.

Large-radius and wrinkle-free pipe bends

Every bend creates resistance in the pipe system. If the bend has too small a radius or is incorrectly positioned, the pressure drop increases, and the vacuum conveyor has to work harder. This can result in lower capacity, unstable transport, or, in the worst case, blockages.

Transport hoses / Vacuum hoses

Hoses are often the most flexible and cost-effective solution in vacuum conveying systems, especially in manufacturing environments where equipment is continually moved, cleaned or reconfigured. They make installation straightforward, reduce the need for custom-built pipe systems, and allow for quick assembly and adaptation. At Provak we offer both PUR and PVC vacuum hoses.

pinch valves

We have a wide range of pinch valves because different products and processes require different solutions. At Provak, we help you choose the right valve type, size and material quality to ensure you get a reliable solution with good flow, a long service life and minimal risk of blockages.

Pipe couplings for stainless steel pipe systems used in vacuum conveying and pneumatic conveying systems for powders and granules.

Pipe fittings and hose connections

With the right pipe couplings and hose sleeves, the pipe system becomes both flexible, secure and easy to service. Pipe couplings are used to connect pipes with the same diameter and are an important part of vacuum and pneumatic conveying systems in the food, plastics, seed/grain, pet food and chemical industries, among others.

Feed nozzles / suction lances / suction tubes

Our Feed nozzles and suction lances make it easy and efficient to convey powder and granules from bags, containers or tanks into a vacuum conveyor system, without unnecessary spillage or contamination. We offer standard solutions in multiple diameters as well as custom-made versions adapted to your process and product.

What type of transport hose?

For a vacuum conveying system, as a rule of thumb, you should choose a food-grade, antistatic and vacuum-resistant conveying hose that is dimensioned according to the powder's properties, the conveying distance and the desired capacity.

When choosing a transport hose for vacuum conveying, one should look in particular at

  • Vacuum class → The hose must be able to maintain its shape under the relevant vacuum level.
  • Antistatic or conductive design → With dry powders, friction can create static electricity. Therefore, the hose should be antistatic or conductive and installed correctly with an earth connection.
  • Food approval → For food, pharma and ingredients, the hose must be FDA/EU-approved.

The optimal transport system often consists of both stainless steel pipes and flexible vacuum hoses. At Provak, we typically recommend a short transparent hose at the inlet of the PIAB vacuum conveyor so that the product flow can be seen directly. This provides increased process control, faster troubleshooting and greater peace of mind in daily operations.

Pinch valves are used in pneumatic conveying systems and vacuum conveying plants, where they ensure reliable regulation and shut-off of powder, granules and other dry materials. The valves provide a free product flow without pockets or dead zones, which reduces the risk of product accumulation and cross-contamination. At Provak, we offer a wide range of pinch valves for integration into stainless steel pipe systems, vacuum conveyors and complete powder handling plants. The solutions are used in, among others, the food, pharmaceutical, chemical and plastics industries, where operational reliability, hygiene and gentle product handling are crucial.

Professional installation of piping and hoses

When you invest in a vacuum conveyor or other process equipment from Provak, it makes good sense to let us handle the installation of pipework and hoses. With many years of experience in pneumatic conveying, we ensure that all components are correctly dimensioned and fitted so that the system achieves maximum capacity, operational reliability and energy efficiency. We take responsibility for the entire solution, from planning and material selection to assembly and commissioning. This means fewer risks, a quicker start-up and the assurance that pipes, bends, hoses and valves work together optimally with the rest of the equipment. The result is a more stable production, less maintenance and a solution that is ready for many years of operation.

How do we ensure correct sizing?

Correct pipe sizing is essential for an efficient and reliable vacuum conveying system. At Provak, we base our approach on your process, material, and capacity requirements to ensure the optimal solution.

  • The material's properties, including density, particle size and abrasive wear.
  • Pipe lengths and number of bends to minimise pressure drop and energy consumption.
  • Selection of hoses, pipe bends, valves and couplings to ensure the components are suitable for the application.
  • Pipe diameters, so that the air speed is correct throughout the system.
  • Integration into existing facilities
