Norgren T84T-4GA-B1N Excelon Plus 3/2 Shut-Off Valve - G1/2
Part Number: T84T-4GA-B1N
Quick Summary
Norgren T84T-4GA-B1N is a compact 3/2 shut-off valve for compressed air automation lines. Engineers often struggle with bulky valves that impede quick maintenance and reliable control. Designed for CE compliance and IP-rated configurations, with tamper-proof padlock options for safe, factory-floor operation. In practice, this modular valve delivers weight savings and faster installation, boosting efficiency and uptime in industrial automation environments. Its G1/2 port size and 20 bar max inlet pressure enable flexible integration into existing pneumatic networks. As part of the Excelon Plus family, it leverages durable die-cast aluminium and nitrile elastomer seals to withstand demanding plant conditions. This combination provides a scalable path to leaner installations through mounting brackets, adapters and quick-clamp options.

FAQs
To install, ensure the compressed air supply is switched off and the line is depressurized. Mount the valve using the Excelon Plus General Mounting Bracket 840024-50KIT or slide-in with the Quikclamp 840014-51KIT. Attach port adapters 840015-11KIT if needed for G1/2 connections, then torque to the recommended spec and perform a leak test. Finalize with rotary knob operation verification and system bleed adjustments as required.
Key specs include medium: compressed air; port size: G1/2; actuation: rotary knob with return; maximum inlet pressure: 20 bar; valve operation: 3/2; flow: 162 dm3/sec (343 scfm); body material: die-cast aluminium; elastomers: nitrile rubber; dimensions: height 70 mm, length 108 mm, width 72 mm; weight: 0.48 kg; operating temperature: -20 to 65 °C.
Yes. It supports Excelon Plus mounting options, including the General Mounting Bracket 840024-50KIT and Port Adaptors 840015-11KIT for G1/2, plus Quikclamp solutions 840014-51KIT and 840014-52KIT. This compatibility enables faster retrofits and scalable expansion in established automation lines without redesigning downstream plumbing.
Regular maintenance should include inspection and, if needed, replacement of nitrile elastomer seals and routine cleaning of the 3/2 valve mechanism. For enhanced security or tamper-resistance, use 840055-01KIT Padlock or 840055-02KIT Padlock Hasp. Monitor flow and operate times; consider the Quietaire silencer T40C2800 for exhaust noise management in noise-regulated environments.
The data provided lists country of origin and general specifications; it references CE and IP-rated configurations as design considerations for the Excelon Plus family. Verify exact CE certification and IP rating for your application in the datasheet (en_8_200_650_T84.pdf) and installation guide (IM_AL_Excelon_Plus_EN.pdf). For critical safety (SIL) requirements, design the system safety architecture accordingly.
