Servo and Proportional Valves with Special Features

Meeting Exacting Needs for Safety and Flexibility

For customers with machines used in demanding environments, Moog offers Servo Valves and Proportional Valves with advanced safety features such as fail-safe options, certifications for use in hazardous environments and special performance modifications.

Moog has a long history of providing valves with advanced features needed for applications that are in demanding or even hazardous environments. For example fail-safe versions of some of our most popular valve models are critical to machines in a variety of applications where workers need maximum protection. Our explosion-proof , flameproof and intrinsically-safe line of products offer special constructions and modifications needed for certification as explosion-proof. 

In addition, Moog frequently tailors products by modifying valve components for improved performance. Moog’s long history of close collaboration with customers means that we have vast experience with designing and building special valves. Examples of this are microvalves manufactured in titanium for minimal weight that are used in motorsports. Another special modification that Moog routinely performs is customized spool null cutting to solve specific system or machine problems.

What is an ATEX or explosion-proof Valve?

There are a range of certifications required for products used where fire or explosion hazards exist due to the presence of flammable gases or vapors, and flammable liquids. ATEX is a global certification for products such as servo valves that are used in these environments and it is typically required by companies that sell into the European Union. A range of levels is defined by the regulations ( e.g. II 2G Ex d e IIC T6/T5/T4/T3 Gb) and Moog engineers will work with you to obtain the performance you need and ensure compliance to appropriate regulations
