FAQs
The T82T-3AA-B1N uses 3/8 in PTF ports and a 3/2 valve operation, designed to integrate with standard pneumatic manifolds and inline circuits. Its compact diecast aluminium body accommodates space-constrained installations, while the rotary knob actuation provides intuitive manual control. When retrofitting, verify port alignment with existing couplings and ensure padlock-ready access if tamper-proof configurations are deployed.
This valve delivers 41 dm3/sec (87 scfm) at up to 17 bar inlet pressure, which directly influences actuator speed and response time in pneumatic cylinders. In high-speed lines, the combination of flow and pressure stability reduces cycle time variation and improves repeatability. Assess system load and downstream line pressure to optimize timing without risking valve chatter or leakage.
Yes, the Excelon Plus T82T-3AA-B1N is engineered for reliable shut-off and fast actuation in automated applications. Its modular design supports quick replacements, tamper-proof options for safe operation, and a rotary knob return for precise cycling. For peak performance, pair with compatible air preparation and clean dry air to minimize contamination and maintain flow integrity.
The Excelon Plus family is designed to align with common industrial safety expectations, including CE-related compliance and options for IP-rated protection. SIL-ready configurations can be supported through accessory and configuration choices. When selecting versions, confirm the specific certification scope with your distributor to ensure it meets your plant’s regulatory requirements.
Regular maintenance should focus on seal integrity, actuator cleanliness, and padlock hardware (for tamper-proof variants). The diecast aluminium body and nitrile elastomer seals resist wear in typical shop air, reducing replacement frequency. The modular Excelon Plus design lowers downtime during changeovers, delivering a favorable total cost of ownership through improved uptime and predictable performance.
