The actuators for proportional valves type F HM G + F HT P consist of a magnet body, and a tube. The solenoid body is fixed with a fastening nut on the tube and can be removed or replaced without opening the hydraulic circuit. The modular design makes it possible to combine the tube also with a solenoid body type F MM E, which has approvals according to ATEX and IECEx for operation in potentially explosive atmospheres.

The proportional valve cartridges with function 3/2 NC are used as pilot valves in hydraulic circuits. The small size and the high degree of protection meet the requirements of mobile applications. They are characterized by a large proportionality between magnetic current and control pressure and a largely constant operating pressure in the flow range

Size (Ø): 30 mm
Control pressure: up to 32 bar
Input pressure: 50 bar (max. static)
Tank pressure: 30 bar (max. static)
Flow: up to 10 l/min

Based on a flexible modular system, we develop and supply control and switch valves for customer-specific requirements in mobile and stationary applications.

In our development, we aim at the following aspects regarding our valves, dependent on their application areas:

·         high pressures

·         low leakage

·         extensive service life

·         temperature and vibration requirements

·         protection classes up to IP6K9K
