Integrate and streamline your design with our compact actuator models, which use the same body and end caps for both double-acting and spring-return mechanisms. This uniformity minimises spare parts inventory, enhancing convenience for customer applications in the field. You can easily modify these actuators by adding or removing spring cartridges, making them highly adaptable and user-friendly.

Our products meet the latest international standards, including ISO 5211, DIN 3337, and VDI/VDE 3845, among others. They are also fully compliant with the NUMAR standard. This ensures easy interchangeability and convenience when replacing or mounting accessories like solenoid valves and limit switches.

Utilise a rack and pinion system with double pistons to benefit from a compact design, extended operational life, and rapid functionality. The tooth surface of the piston, processed via a CNC machining centre, ensures enhanced gear efficiency and precise transmission. This leads to stable and dependable performance. Additionally, altering the rotation direction is straightforward—simply reverse the pistons, thanks to the design’s symmetrical mounting capability.

Dual independent travel stoppers allow for precise and convenient external adjustments of ±5° in two directions. This enables actuators to align with the valve during both the opening and closing phases of the stroke.

Composite bearings and guides in both the pinion and piston guarantee precise functionality, minimal friction, and extended durability. This design effectively safeguards the output shaft against fractures.

The specialised sealing ring positioned between the body and cylinder prevents initial failure due to the suction of the rubber plug. This feature enhances safety, ensures a leak-proof seal, and extends the product's lifespan.

The rack and pinion tooth is engineered with a superior tooth profile ratio for minimal clearance, ensuring precise driving and enhanced output power. This high-precision design delivers reliable performance and efficient power transmission.

The body of the extruded aluminium is treated to resist corrosion both inside and out. A finely ground cylinder surface results in a low coefficient of friction and extends the product's cycle life significantly.

Preload spring cartridges featuring a specialised coating are suitable for numerous applications, offering enhanced security and resistance to corrosion. These modular units are designed to function effectively in various environments, ensuring reliability and long-lasting performance.

High-quality bearings feature reliable seals, low friction, extended service life, and a broad application temperature range.

Premium valves use higher grade materials like 316 stainless steel or chrome plated brass for better corrosion resistance and durability. Other options include PTFE seats and silicone balls.

End connections for premium valves include threaded, socket weld, butt weld, and flanged in sizes from 1/4" to 2" for various applications. Sanitary tri-clamp connections are also available.

Pressure ratings reach up to 6000 psi with high temperature ratings around 800°F depending on the materials used. Always verify the manufacturer's pressure vs temperature chart.

A floating ball is not fixed to the stem but floats between two seats. This provides even sealing and prevents leak paths during thermal expansion.

Graphite in the ball dissipates static electricity that could otherwise ignite flammable fluids during flow. This adds safety.

PTFE, silicone, viton, and other resilient seal materials allow tight shut off even after thousands of cycles. Metal seats can also be found in high temperature designs.

For applications with very high differential pressures, a blow-out proof stem has upper and lower seals to prevent leaks if overpressure blows the stem upwards.

Locking mechanisms like padlocks, valve locks, or tamper-proof handles prevent unauthorised operation or accidental valve position changes.

100% testing involves leak checks, seal validation, and flow performance verification to ensure perfect functioning and no defects.

Look for ISO 9001, PED 97/23/EC or ATEX certifications that indicate quality manufacturing and safety compliance.
