High-flying solutions

Value Engineered Products (VEP) is a leading designer and manufacturer of aerospace class pressure, vacuum and differential pressure switches for air and compatible fluids. Part of the USA-based World Magnetics family - represented exclusively in the UK and Europe by Variohm EuroSensor - VEP’s products are characterised by what are said to be "exceptional precision, durability, reliability and long working life".

With five product series’ designs covering low, mid-range and high-pressure switching from 0.01 to 3,000 PSI, VEP’s extensive list of field proven application areas include air speed and airflow detection, landing gear and brake safety systems, rudder control assist and other demanding precision pressure switching tasks where accuracy, stability and repeatability are primary requirements.

Harsh environments

Developed for harsh aerospace environments, each of VEP’s five product series’ cover pressure, vacuum or differential switching with wide flexibility in mechanical and electrical options. For example, VEP’s 490 series has field adjustable pressure ranges from 3.0 to 3,000 PSI in a lightweight gold-plated aluminium housing with a dual-spring and stainless-steel piston design that maximises accuracy and stability as well as allow high proof pressure to 4500 PSI.

Designed to meet FAA’s 15-minute flame test requirement, the 490 has an altitude range from -1000 to 50,000 feet and, like all other product series available, offers SPDT switching at 5 Amps-resistive from a 30 V DC supply.

Range of models

Other VEP models cover low-pressure and medium-pressure switching – the 654 series covers a 0.1 to 6 PSI setpoint range, while the 648 series range is 40 to 500 PSI. High temperature versions, shock- and vibration-resistant models, aluminium and optional stainless-steel housings, and a selection of seal materials fulfil durability requirements throughout the complete range.

“As well as field-adjustable setpoints, factory-set and tamper-proof models are available. SPDT and DPDT switching and comprehensive pressure port and electrical interfacing options ensure that applications are fully met without compromise, although a custom design service is also offered,” states Variohm EuroSensor.
