541267-0A-MO Festo MS6-EM1-1/2 Manual On-Off Pneumatic Valve
541267-0A-MO is Festo MS6-EM1-1/2 manual on-off pneumatic valve belonging to Festo MS service unit series, a 3/2-way rotary gate shut-off valve specially designed for compressed air pipeline safety cut-off in industrial pneumatic systems. It adopts G1/2 female thread connection for air ports, supporting working pressure from 0 bar up to 18 bar, with high nominal flow rate of 8700 l/min, which can meet large air flow demand of automated production lines. The valve body is made of die-cast aluminum, featuring lightweight structure, high mechanical strength and moderate corrosion resistance, suitable for factory workshop environment.
This manual shut-off valve is operated via rotary hand switch. When switched off, it can rapidly exhaust residual pressure inside downstream pipelines to ensure safe maintenance of pneumatic equipment. It works with compressed air or inert gas that meets ISO 8573-1 standard. The operating temperature range covers -10℃ to 60℃, adapting to temperature variation of workshop. Its non-reversible flow direction design avoids wrong installation, and it supports inline assembly or modular stacking with other MS series air service units such as filter, pressure regulator and lubricator, greatly simplifying air preparation station layout.
541267-0A-MO is widely applied in automation machinery, packaging equipment, textile machines and assembly lines. As a key safety component of pneumatic circuit, it isolates air source during equipment overhaul to prevent accidental cylinder movement and protect maintenance operators. This spare part is frequently required for renovation and maintenance of old pneumatic stations. Replacing damaged valve with identical model can directly fit existing manifold and pipeline thread without modifying air circuit design, saving reconstruction time and material cost.
We supply fully tested 541267-0A-MO spare valves. Before shipment, every unit undergoes air tightness test, switch action inspection and flow performance verification. We check valve sealing performance to eliminate internal leakage, and confirm smooth rotation of manual knob without jamming. All products are covered with 12-month warranty. Our technical team can provide remote support for pipeline assembly, air circuit debugging and fault diagnosis. Fast global shipping is available for urgent maintenance orders.
For pneumatic maintenance engineers and automation integrators, 541267-0A-MO provides reliable pipeline cut-off function. It ensures safe operation of air preparation units, protects downstream pneumatic actuators and sensors, and helps maintain stable running of legacy pneumatic systems, avoiding expensive redesign of whole air source processing station.
