SIEMENS Actuator GLB141.9E

Core Features "GLB141" Series & Functional Design: The "GLB141" denotes Siemens’ ultra-light-duty linear actuator series, specialized for micro-scale hydronic valve control. The "9E" model is a 24V AC-powered linear actuator with a 7 mm stroke length and 400 N thrust rating (≈40.8 kgf)—ideal for tiny 2-way hydronic valves (e.g., residential underfloor heating micro-valves, small appliance fluid valves) where 24V low-voltage power, compact size, and reliable performance are critical. Basic Control Modes & Optional Feedback: Equipped with simple control to meet micro-flow needs: On/off control (24V AC input): For basic full-open/full-close scenarios (e.g., residential heating zone on/off), ensuring reliable flow regulation with rapid actuation (≈2.3 seconds/full stroke). Modulating control (0–10V DC input, optional): For precision micro-flow adjustment (e.g., small office mini-split temperature trimming), enabling valve opening adjustment with ±3.5% positioning accuracy—sufficient for non-critical micro-environment control. It includes optional analog position feedback (0–10V DC) for valve status monitoring, compatible with residential smart thermostats or small appliance control boards. Ultra-Compact & Lightweight Build: Engineered with a flame-retardant high-impact plastic housing (UL94 V-0) and an ultra-lightweight design of 0.38 kg (0.84 lbs), suitable for direct micro-valve mounting (via micro ISO 5211 flange) or bracket installation in extremely tight spaces (e.g., underfloor heating manifolds, appliance interiors). The housing features IP44 protection (dust-resistant, splash-proof), making it compatible with indoor residential and small commercial environments (e.g., apartments, convenience store coolers). Safety & Reliability Features: Built with safeguards for micro-scale operation: Overthrust protection: Automatically stops the motor if thrust exceeds 400 N (e.g., valve stem jamming from mineral buildup), avoiding damage to the tiny valve or actuator. Mechanical end stops: Prevent over-extension beyond full open/close positions, protecting delicate micro-valve seals and extending service life. 24V low-voltage safety: Designed for 24V AC (50/60 Hz) input with ±10% voltage tolerance, eliminating electrical hazards in occupied or appliance-mounted spaces. Simplified Installation & Integration: Designed for plug-and-play setup with no complex programming—works with Siemens residential controllers (e.g., RLU series) and third-party devices via standard 24V on/off or 0–10V signals. It includes a micro ISO 5211 flange (fits most tiny hydronic valves) and color-coded wiring terminals, reducing installation time to under 10 minutes for most applications. Typical Applications SIEMENS Actuator GLB141.9E is engineered for ultra-light-duty linear control of tiny hydronic valves—ideal for scenarios needing 400 N thrust, 7 mm stroke, and 24V power in residential or small commercial systems. Key use cases include: Residential Underfloor Heating: Controlling tiny 2-way valves in residential underfloor heating zones (e.g., bathrooms, walk-in closets). On/off control manages zone heating, while ultra-compact size fits manifold enclosures—complying with EN 12831 (residential heating design) and ASHRAE 90.2 (residential energy efficiency). Small Commercial Appliance Hydronics: Regulating micro valves in small appliances (e.g., countertop water heaters, compact beverage dispensers). Optional modulating control adjusts fluid flow to maintain appliance temperature, and IP44 protection withstands appliance moisture—complying with EN 15502 (appliance standards). Residential Mini-Split Hydronic Add-Ons: Adjusting valves in residential mini-split hydronic coils (e.g., ductless heating accessories). 24V low-voltage compatibility aligns with mini-split control systems, and lightweight design avoids coil strain—complying with EN 14511 (small HVAC components). Light Commercial Display Case Cooling: Controlling tiny valves in small commercial display case cooling systems (e.g., bakery pastry cases, convenience store snack coolers). Simple on/off control maintains cooling flow, and compact size fits display case enclosures—complying with EN 15377 (commercial refrigeration standards).
