Pneumatic Actuated Valve Manufacturer in Europe – Valvesonly Europe (Germany)

Valvesonly Europe manufactures pneumatic actuated valves in Germany for automation across oil & gas, petrochemical, marine, chemical, power, and water treatment industries. Our actuator-valve assemblies combine durable valve designs with high-performance pneumatic actuators, ensuring fast response, reliable sealing, and long cycle life.

Function & Working

A pneumatic actuator uses compressed air to generate rotary or linear motion. The actuator can be configured as:

• Single-acting (spring return): Provides failsafe operation—automatically closes or opens on air failure.

• Double-acting: Air pressure drives both opening and closing, giving faster operation and balanced torque.

Actuators are integrated with positioners, solenoid valves, and limit switches for on/off or modulating control, making them suitable for both isolation and precise throttling.

Actuator Features & Options

• Torque Output: Up to 20,000 Nm, suitable for large-diameter valves

• Operating Pressure: Standard 5.5–8 bar (customizable up to 10 bar)

• Control Modes:

  • On/Off (basic open/close)

  • Modulating with pneumatic or electro-pneumatic positioners (4–20 mA signal)

• Cycle Time: As low as 1–2 seconds for small valves; scalable for large-bore service

• Housing: Anodized aluminum alloy, stainless steel, or epoxy-coated steel for corrosion resistance

• Temperature Range: –40 °C to +120 °C (special seals available for –60 °C cryogenic or +180 °C high-temperature duty)

• Enclosures: IP67 / IP68 protection; ATEX-certified explosion-proof designs available

• Accessories: Solenoid valves, limit switches, air filter regulators, manual override, quick-exhaust valves, and fail-safe systems

• Standards Compliance: Designed to NAMUR VDI/VDE 3845, ISO 5211 mounting for actuator-to-valve compatibility

Advantages

• Rapid actuation for frequent cycling applications

• High torque-to-weight ratio for space-saving design

• Long cycle life with self-lubricating bearings and corrosion-resistant housings

• Fail-safe spring return ensures safe operation during air supply failure

• Compatible with advanced process automation (Modbus, Profibus, Foundation Fieldbus via smart positioners)

• Explosion-proof and SIL-rated options for safety-critical industries
