Valbia pneumatic actuators are high-performance, rack-and-pinion quarter-turn actuators engineered for industrial automation of ball, butterfly, and plug valves. Built with compact, corrosion-resistant construction, they offer reliable actuation with a variety of rotational and operating modes, backed by a patented design that enhances longevity and reduces leak paths.
Choice of 0–90° or 0–180° rotation via three series
Robust alloy construction with anti-blowout rack design
Custom coatings and seals for extreme environments
Twin rack-and-pinion for balanced torque and compact form
Standard FKM (Viton); optional silicone or low-temp variations
Output shaft: ISO 5211
Solenoid interface: Namur pattern
ATEX Zone 1/2 certification for explosive environments; PED/CE compliance
Series 82/83: Extruded hard-anodized aluminum bodies with nickel-plated steel pinions
Series 84: Stainless steel bodies for enhanced corrosion resistance
±5° via stainless steel cams and bolts
Max Pressure: ~8 bar (116 psi)
Operating Temp Range: –40 °C to +150 °C (depending on seals and coatings)
Industrial process actuation in chemical, food, and water sectors
Automation of valves in corrosive, high-temp, or cryogenic environments
High-cycle and safety-critical operations using modulating or failsafe versions
Marine and offshore valve automation requiring rugged design
Highly durable, low-maintenance rack-and-pinion mechanism
Precision control with tight end-position adjustment
Uniform torque output for consistent valve operation
Multiple material and finish combinations to match process conditions
Safe differential mounting/interface for accessories like limit switches or solenoids
Spring-Return (SR) Versions: Fail-safe function for valve positioning under pressure loss
Double-Acting (DA) Versions: Controlled open and close via air pressure in both directions
Special Finishes: Nickel plating or PTFE coatings for maximal corrosion resistance
High/Low Temp Options: Silicone, Viton, or NBR seals to suit extreme thermal environments
Accessories: Solenoid valve mounts, limit switches, manual overrides, and positioners
From forging and casting to machining, assembly, and testing — every step is managed under one roof to ensure consistent quality, faster lead times, and zero compromise.
