Pinch Valve Vacuum – Reliable Functionality
Pinch Valve vacuum technology puts great emphasis on the quality of the components and reliable functioning of pinch valves. Shutoff valves in vacuum systems are subject to several special requirements, apart from the general shutoff elements and their technical aspects. With pinch valve vacuum, the additional demands are met only when the right shutoff devices are installed, taking into account the method of construction, operation, and size suitable for each application.
Below is a video showing how a vacuum system works on a Pinch Valve, to combat the problem of vacuum pressure pulling the rubber sleeve inside the valve partially closed, obstructing the flow of product.

Pinch Valve Vacuum Characteristics
A vacuum shutoff pinch valve must perform three main functions:
- Control flow media to achieve the desired pressure
- Provide complete isolation for vacuum volumes from pumps
- Ensure seamless transfer of objects between those volumes.
Although the basis of its main design depends on function, the specifications of pinch valve vacuum are determined by user convenience and application. Some common construction materials include brass, aluminum, and stainless steel. The choice of material is dependent on the required pressure range, temperature, and the material of the other components in the system.

Absolute tightness of pinch valve vacuum is of utmost importance, especially in applications where high or ultra-high vacuum needs to be achieved. Other crucial factors with pinch valve vacuum include low maintenance requirements, long service life, and short closing and opening times, which can arguably be attained using a high quality, pinch type vacuum shutoff valve.
A Pinch Valve by AKO benefits from all of these advantages needed above.
Pinch Valve Vacuum Wide Variety of Types
There are a wide variety of pinch valves available that are specially designed for particular applications to be used in vacuum technology. However, they are named differently, based on their function and body construction. Several valve actuation choices are available in the market, such as solenoid electric, pneumatic, and manual. Some of the highlighting features include roughing points, high conductance, position indicator, heater jacket, and integral window. Vacuum shutoff valves that are considered to have fail-safe mechanisms include normally open or spring-to-open and normally closed or spring-to-close.
