Henry G. Dietz

Why Henry G. Dietz™ - Both rugged and precise, Henry G. Dietz (Dietz) pressure switches are the ideal choice for long-lasting, repeatable performance in harsh industrial environments. Heavy-duty housings and mounting brackets protect internal components in applications such as construction and earth-moving equipment, marine and rail transportation, and chemical and sewage plants. Many models have field-adjustable actuation points, and the Dietz Model 170D is shock and vibration resistant.

From air pressure and air flow detection to protection of air-cooled electronic equipment, Henry G. Dietz pressure, vacuum, and differential switches will provide years of precise, reliable performance.

Value Engineered Products - VE Products - VEP

Why VEP™ - Both lightweight and precise, VEP (VE Products) pressure switches are the ideal choice for long-lasting, repeatable performance in the most demanding aerospace applications. The piston and dual spring design allows the switch to be used in high proof pressure applications where accuracy and stability is critical such as landing gear & braking systems. Many models are shock and vibration resistant as well as being available in stainless steel which allows them to meet the FAA 15 minute flame test requirement.

From air speed and airflow detection to landing gear and brake safety systems, VEP pressure, vacuum and differential switches will provide years of precise, reliable performance.
