Norgren V64H-6GD-RMN Pressure Relief Valve - Category 0 SEP CE
Part Number: V64H-6GD-RMN
Quick Summary
Norgren V64H-6GD-RMN pressure relief valve protects compressed air systems by automatically venting excess pressure where it matters most. Without reliable relief, production lines suffer unexpected trips, equipment damage, and costly energy waste during start-up and peak demand. This valve is designed for Category 0(S.E.P.) and Category 1 compliance under the PED 97/23/EC and carries CE conformity, ensuring regulatory compatibility in European installations. The unit delivers high relief capacity with precise response and a threaded exhaust port for silencers or piped exhaust, enhancing safety and noise performance. For engineers and maintenance teams, the Olympian Plus family offers easy integration with standard G3/4 ports and serviceability through the V64H-KIT and compatible silencers.

Feature → Business Impact → Application: High relief capacity and sensitive response deliver reliable overpressure protection, reducing the risk of equipment damage and unplanned downtime in fast-changing pneumatic lines. This translates to improved line uptime and safer machine operation on packaging, automation, and tooling stations that rely on stable air pressure. Application: install on main distribution lines where sudden surges occur. Feature → Business Impact → Application: Outlet pressure is adjustable from 1 to 10 bar (15 to 145 psi) with a Rc1/8 gauge port for monitoring. Benefit: precise pressure control, better process stability, and easier validation during commissioning for automated equipment. Application: CNC control benches and high-precision feeders where tight pressure tolerance matters. Feature → Business Impact → Application: Robust materials—body and bonnet in zinc, adjusting knob in plated steel, elastomers from synthetic rubber—provide corrosion resistance and long service life in harsh factory environments. Benefit: lower replacement costs, reduced maintenance interrupts, and predictable performance over time. Application: heavy-duty workshops and compressor rooms subject to humidity and dust. Feature → Business Impact → Application: Compliance with PED Category 0(S.E.P.) and Category 1, plus CE marking, reduces regulatory risk and supports multi-site European deployments. Benefit: smoother audits, faster project approval, and improved supplier qualification. Application: any mid- to large-scale industrial installation requiring certified safety and reliability. Feature → Business Impact → Application: Broad compatibility with Olympian Plus accessories, including T64T-6GB-P1N shut-off valves, silencers MB004B and T40B1800, and service kit V64H-KIT, streamlines upgrade paths and maintenance planning. Benefit: simplified procurement, faster retrofits, and lower total cost of ownership. Application: systems upgrading from older relief valves or integrating into existing Olympian Plus manifolds. Feature → Business Impact → Application: Easy mounting via standard G3/4 port and integrated exhaust options enable straightforward installation and quieter operation. Benefit: reduced installation time and improved worker safety with quieter plant floors. Application: new machine lines and retrofit projects where space and noise are considerations.

FAQs
Install the valve on a G3/4 port with the Rc1/8 gauge port accessible for monitoring. Use the Olympic Plus mounting options (e.g., wall bracket 74504-50) for secure placement, and consider integrating MB004B or T40B1800 silencers to minimize noise. Ensure the system pressures stay within the 1–10 bar range for reliable operation.
Adjust the outlet pressure within 1 to 10 bar (15 to 145 psi) using the adjusting knob. For real-time verification, connect a gauge to the Rc1/8 gauge port. After setting, perform a brief pressure test under normal operating conditions to confirm stable relief behavior and prevent nuisance trips.
The V64H-6GD-RMN complies with Category 0(S.E.P.) and Category 1 of the PED 97/23/EC and carries CE marking. These certifications support regulatory compliance in European installations and help with audits, qualification of suppliers, and safety assurances for pressurized air systems.
Yes. The V64H-6GD-RMN is designed for compatibility with Olympian Plus accessories such as T64T-6GB-P1N shut-off valves, service kit V64H-KIT, and silencers MB004B and T40B1800. This enables straightforward retrofits, maintenance, and performance tuning within existing Olympian Plus configurations.
Typical applications include packaging lines, automated tooling, CNC machines, and general pneumatic circuits where precise relief protection is critical. The ROI comes from reduced unplanned downtime, protection against costly over-pressurization events, and lower maintenance costs due to durable zinc housings and readily available service kits.
