Aluminium alloy body with nitrile seals delivers durable reliability in harsh environments. This combination minimizes corrosion, wear, and maintenance costs, reducing total cost of ownership over the valve’s life. The result is predictable exhaust performance in standard pneumatic lines and in mobile equipment where vibration and dust are common. G3/8 port size and G3/8 thread provide straightforward compatibility with common fittings and piping. That standardization reduces installation time and leakage risk, making retrofits faster and more cost-effective. Applications include retrofit on existing cylinder circuits and new automation lines. Operating range from -20 to 80 C and a working pressure of 0.5 to 10 bar ensure reliable performance across factory floors and outdoor plants. This broad range supports multiple cylinder sizes and service profiles, reducing the need for multiple part variants. In practice, you gain flexibility when designing pneumatic loops and buffering exhaust phases. Rapid exhaust action cuts vent time and unlocks higher cylinder speeds in high-speed automation tasks. The measurable impact includes shorter cycle times, improved throughput, and reduced compressor load. This also helps meet energy efficiency targets by avoiding unnecessary pressure hold during venting. Simple, compact design eases retrofit and new installations, and reduces training time for maintenance staff. CAD models and a Datasheet are readily accessible in the downloads section to accelerate engineering work. CE compliance and robust materials, the T70C3800 supports reliable, compliant operation in industrial environments.

FAQs
For proper installation, use standard G3/8 fittings and threads, ensure the supply is within 0.5 to 10 bar, and mount the valve in a location with clean, dry compressed air. Verify orientation for gravity-assisted exhaust if applicable and protect lines from vibration. Refer to the datasheet and CAD resources for recommended mounting clearances and compatible fittings.
The T70C3800 provides rapid exhaust of air from reservoirs and cylinders, reducing exhaust lag and allowing cylinders to reach speed targets faster. In high-speed automation tasks, this translates to shorter dwell times, increased throughput, and improved overall production efficiency without adding complexity to the control logic.
The valve is CE compliant for European markets, meeting applicable safety and performance directives. For SIL-related safety architectures, verify compatibility via the datasheet and confirm the overall system integration with your safety circuits; individual certification for SIL may depend on the broader safety chain and configuration.
Operating temperature range is -20 to 80 °C, and operating pressure is 0.5 to 10 bar. The medium is compressed air, and it uses a G3/8 port with G3/8 threading. Materials include an aluminium alloy body and nitrile seals, with range designation in the T70 family.
