FAQs
Begin by verifying panel cutouts match the valve dimensions and ensure a clean, dry air supply. Mount the valve using the provided brackets, connect the 3/4" PTF inlet and outlet lines using proper flanges or fittings, then route the 1/4" exhaust to a safe exhaust or silenced outlet. Finally, test for leaks and confirm lockable actuation operates smoothly. The T68H-6AB-B2N is designed for straightforward retrofit into existing 3/2/4/2 manifold configurations, minimizing downtime during installation.
With a flow rating of 451 dm3/sec (956 scfm), the valve supports multiple actuators or higher-demand cylinders within a single pneumatic loop. This capacity reduces the risk of pressure drop during peak cycles and helps maintain consistent actuation force. When sizing, consider the number of actuators, cycle frequency, and line losses to ensure the 17 bar inlet pressure delivers the required flow.
The valve features an aluminium body and nitrile rubber elastomers, delivering robust performance under typical factory conditions. Its operating range of -20 to 80 °C broadens applicability across cold rooms and hot manufacturing areas. For outdoor or particularly harsh settings, confirm installation protection, sealing integrity, and potential coating needs to resist environmental exposure.
The provided data does not specify certifications such as CE, SIL, or IP ratings. It is essential to consult the official datasheet or contact the supplier to confirm applicable certifications for your industry and region. When regulatory compliance is required, request formal documentation and ensure the product meets your company’s safety and quality standards.
The T68H-6AB-B2N’s lockable operation reduces unscheduled shut-downs by preventing unintended actuation during maintenance, enhancing safety and uptime. The aluminium body and nitrile seals support durable service life with lower replacement frequency, contributing to lower maintenance costs. Its compact size also simplifies spares inventory and faster module replacements, improving overall return on investment in automated lines.
