Miniature valve MH1 Mini

Extremely small, fast, flexible and durable – that sums up the MH1. Its size

makes it ideal in tight spaces and it comes complete with vacuum functions. It is totally reliable, even during 24-hour operation and with 100% duty cycles.

New: the pilot valves VUVG in the MH1 range. This further expands the plug and connection concepts for the miniature valves with IP40 and IP65 protection, adding an M8 connection with IP65 protection.

White paper: Automating on/off process valves A comparison of actuation methods for pneumatic actuators

On/off process valves can be automated in different ways using pneumatics. This white paper looks at automation using an individual valve, a valve terminal and a digital valve terminal, and compares the three actuation methods in terms of:

• Required hardware/components and the installation

effort involved

• Investment costs

• Potential for compressed air savings and increased

energy efficiency

• Diagnostic and maintenance options

• Potential for function integration

• Possible applications in safety-related circuits

• Possible applications in potentially explosive areas

ET 200 SP Diagnostic Interrupts When Using Valve Terminals

When valve terminals are used, short-circuit and short-circuit detection of the safe output modules of the Siemens ET 200 SP may result in diagnostic interrupts. These diagnostic interrupts can lead to the fact that an operation is not possible. This technical report explains the background and suggests possible solutions.
