Vacuum Valves

A simple vacuum system includes a vacuum pump, a vacuum chamber and a vacuum valve. Vacuum valves are available in many versions. Many different criteria are important to choose the right valve. For example, the decision as to which valve should complement your system is based first and foremost on the question of whether the valve should have a purely isolating function or a controlling function. Another important question is the space available in your system.

General tips guiding you to the right choice of valve:

If you are looking for a new valve, we recommend that you consider a few points. Here you will find an overview of the most important questions before buying:

• What is the purpose of the valve?
Depending on this, the type of the valve should be chosen.

• What does the installation space look like?
That decides about what size should be selected.

• What functions should the valve have?
This becomes important with increasing complexity or automation of the plant.

• Does the valve have to fit into an existing plant?
The communication between the products within a plant is very important.

• What pressures is the valve exposed to?
Important to know in order to decide the sealing material that should be used.

• What gases is the valve exposed to?
No matter what gases you pump the choice of materials is crucial here.

• What temperatures is the valve exposed to?
Good to know in order to determine the material from housing and sealing.

To give you a better overview our valves are divided into the two categories Isolation valves and Pressure control valves.

Isolation Valves

On the one hand there is the Isolation valves section. Here you can find angle, inline, ball and gate valves, manually operated as well as pneumatically operated. Pneumatically operated valves are available with and without position indicators also called limit switches. The pilot valve turns a pneumatically actuated valve into an electro-pneumatically operated one. Pilot valves are also known as solenoids or control valves. With pilot valve and position indicator the vacuum valve can be controlled by a programmable logic controller (PLC) or a similar controller. So, for example, Angle valves are frequently used in freeze-drying, partial drying, or gas separation. In comparison, gate valves are generally used wherever large nominal sizes are needed (> DN 100), such as in coating systems. Depending on demand, many of our vacuum valves are available in aluminum and stainless steel.

Pressure Control Valves

On the other hand, there is the Pressure Control valves section. This section includes butterfly valves or pendulum valves, with and without sealing technology, operated with or without controller. Every complete downstream pressure control system design incorporates three components including a throttle valve, valve controller and vacuum gauge. The control valves are for controlling pressure as well as for the measured gas supply in vacuum systems. Products from this section are the best fit for your semiconductor or coating application.
