01

Proportional
Valves and Controls

Offerings range from simple proportional valves to servo-proportionals with on-board digital drivers and LVDT transducers for high-precision motion, pressure, and speed control

Subplate and cartridge formats (ISO sizes 06–35, up to 125) support directional, pressure, and flow control applications with configurable electronics (I/O Link and others)

Digital axis cards enable closed-loop axis and P/Q control for position, speed, and force in hydraulic actuators, including explosion-proof variants

02

On-Off Valves (Directional / Safety / Modular)

A full range of solenoid-operated on-off valves in subplate and screw-in cartridge formats, engineered for low-leak and low-power operation. Options include mechanical, hydraulic, or pneumatic actuation, with ISO sizes up to 32 and flows up to ~700 l/min (350 bar)

Safety valves with inductive spool/poppet position monitoring, cURus certification, and compliance with EU Machinery Directive (2006/42/EC) and PED 2014/68/EU, with capacities to ~6,300 l/min and pressures up to ~420 bar

Modular valves allow configurations of flow, pressure, and directional controls—mountable under ISO solenoid valves typical in industrial builds

03

Flow, Pressure & Check Valves

Pressure-compensated flow control valves, with or without LVDT transducer and digital drivers, with flows ~45–90 L/min and pressures up to ~210 bar

Pressure control valves: relief, reducing, sequence and compensator valves offered in screw-in, subplate and in-line styles—with or without electronics, typically up to 420 bar

Check valves: leak-free directional designs, direct or pilot operated, in screw-in or in-line formats. Flow ranges up to ~500 L/min, pressure ratings 315–400 bar

04

Cylinders, Pumps & Filters

Hydraulic cylinders, built to ISO 6020/6022 standards; diameters from 25 to 400 mm, strokes up to 5 meters, pressures up to ~320 bar. Special versions are available for explosive environments, as well as stainless steel options for harsh conditions.

Hydraulic pumps: axial-piston variable displacement (PVPC series) and fixed-displacement vane pumps (PFE series). Designed for high pressure, low noise, long life, and available in ATEX-certified versions for hazardous zones.

Filtration solutions: inline, return-line, and suction filters using high-efficiency microfiber elements to maintain fluid purity and extend component service life.
