Feature → High relief capacity and sensitive actuation. Business Impact → Rapidly relieves excess pressure, minimizing spikes that can stress compressors and actuators, improving line stability and reducing unplanned downtime. Application → Ideal for heavy pneumatic circuits in packaging, automation, and process-control stations. Feature → Adjustable outlet pressure from 1 to 10 bar with a maximum inlet of 17 bar. Business Impact → Lets engineers tailor relief to specific tools and processes, maintaining consistent downstream pressure and safeguarding delicate components. Application → Useful across multiple tool stations and end-of-arm tooling where precise pressure control matters. Feature → Threaded relief port for silencers or exhaust piping. Business Impact → Enables quiet operation and easier exhaust management, supporting worker comfort and compliant noise levels. Application → Plants deploying Quietaire silencers or routed exhaust lines. Feature → CE and PED compliance (Category 0 and 1). Business Impact → Regulatory alignment facilitates audit readiness and asset acceptance in regulated environments. Application → Suitable for industrial automation projects requiring formal certification. Feature → Durable materials (zinc body/bonnet, plated steel knob, synthetic rubber elastomers). Business Impact → Long service life in harsh plant environments with reliable sealing and easy maintenance. Application → Heavy-use installations in factories with wide temperature ranges. Feature → Availability of service and accessory ecosystem (V64H-KIT, MB004B silencers). Business Impact → Supports proactive maintenance and rapid retrofits, reducing downtime. Application → Easy serviceability and upgrade paths for ongoing reliability.

FAQs
Install using standard G3/8 port connections and ensure Rc1/8 gauge port is accessible for pressure monitoring. Use compatible silencer or exhaust fittings and consider mounting hardware like the Wall Bracket if space is restricted. Verify the assembly is clean, free of debris, and tightened to manufacturer torque recommendations.
Check the maximum inlet pressure (17 bar) and the adjustable outlet range (1–10 bar). Confirm the porting: G3/8 main port, Rc1/8 gauge port, and the operating temperature range of -20 to 80 °C to ensure compatibility with your production environment.
Yes. The valve provides high-relief capacity with precise adjustment, making it well-suited for packaging lines, assembly stations, and other automation controls where stable downstream pressure is critical and over-pressurisation must be avoided.
The valve is CE compliant and PED compliant under 97/23/EC (Category 0 and 1). This matters for regulatory audits, safe operation under European standards, and smoother authorization of equipment in regulated facilities.
Use the V64H-KIT service kit for periodic maintenance, and consider SILENCER accessories like MB004B for noise reduction. The system is designed for easy serviceability and compatibility with other Olympian Plus accessories to minimize downtime and extend service life.
