Magnet-Schultz FHMG + FHTS On-Off Hydraulic Solenoid
Overview
The Magnet-Schultz FHMG + FHTS is a tube-and-coil on-off hydraulic solenoid engineered for high-performance actuation of hydraulic and special valves in demanding industrial environments. Supplied as a two-part assembly – the FHMG pressure-tight tube and armature, paired with the FHTS coil – the FHMG + FHTS series is the current replacement for Magnet-Schultz’s earlier GHPY solenoid range, delivering the same robust push-type actuation with updated construction and documentation.
Seven Star LLC supplies the Magnet-Schultz FHMG + FHTS as an authorized partner of Magnet-Schultz, supporting hydraulic system integrators, valve manufacturers, and industrial maintenance teams across Muscat, Sohar, Salalah, and the wider Sultanate of Oman. Genuine Magnet-Schultz solenoids, coil assemblies, and plug connectors are available through Seven Star LLC for new hydraulic valve builds and field replacement programs throughout the GCC.
Measurement and Operating Principle
The FHMG + FHTS operates as a push-type electromagnetic actuator: energizing the FHTS coil generates a magnetic field that drives the armature within the pressure-tight FHMG tube, converting electrical current into linear mechanical force to shift the spool of a connected hydraulic or special valve. The solenoid delivers an increasing magnetic force versus stroke characteristic, meaning force output rises as the armature approaches full stroke, providing efficient operation and quick response times suited to on-off valve switching duties.
With overall stroke of 4–8mm and working stroke of 1.5–3.5mm depending on the coil diameter selected, the FHMG + FHTS is rated for a 100% duty cycle, allowing continuous energization without derating – an important characteristic for hydraulic circuits where the solenoid must remain actuated for extended periods. Nominal working pressure reaches up to 250 bar depending on model, with the pressure-tight armature tube isolating the electromagnetic coil from the hydraulic fluid circuit.
Engineering Design of the Magnet-Schultz FHMG + FHTS
The FHMG + FHTS is available in three coil diameters – 37mm, 45mm, and 63mm – allowing selection to match the force and pressure requirements of the connected valve. Class F thermal insulation on the FHTS coil supports continuous-duty operation under sustained electrical loading, while the assembly achieves protection ratings from IP65 up to IPX9K when correctly fitted with the Magnet-Schultz ZKBX-G plug connector, suiting both standard industrial environments and high-pressure washdown applications.
Fastening via a central thread allows the coil body to be replaced independently of the pressure tube without disturbing the hydraulic circuit or breaking hydraulic connections, simplifying field maintenance and reducing downtime during coil replacement. A manual override provides operational flexibility for manual valve actuation during commissioning, testing, or emergency operation, and the robust stainless steel and engineered polymer construction ensures compatibility with all neutral fluids commonly used in hydraulic systems.

Industrial Applications
The FHMG + FHTS is used across hydraulic directional control valves, on-off shutoff valves, and special valve actuation in mobile and industrial hydraulic systems, including construction equipment, industrial presses, and process plant hydraulic power units. Its high-pressure rating and 100% duty cycle make it suited to demanding continuous-duty hydraulic circuits where reliable, repeatable on-off actuation is essential to safe and efficient equipment operation.
