FAQs
Install the V64H-4GD-RMN directly onto a G1/2 ported line; the Rc1/8 gauge port provides an available path for pressure measurement or diagnostic sensing. Use appropriate fittings to ensure seal integrity and torque specifications, and consider the threaded relief port if you plan to add a silencer for noise control. The valve is designed for straightforward retrofits in standard industrial pneumatic systems, minimizing downtime during upgrades.
The valve is rated for a maximum inlet pressure of 17 bar and offers an adjustable outlet pressure from 1 to 10 bar (15 to 145 psi). This range supports precise relief in diverse applications, from general plant air systems to high-demand manufacturing lines. Operating temperature is -20 to 80 °C, enabling use in both cold and warm environments without performance loss.
Yes, it suits high-speed lines due to its fast relief response and compact Olympian Plus design. For installation, ensure alignment with G1/2 piping and use the Rc1/8 gauge port for monitoring if needed. If noise is a concern, attach a Quietaire silencer via the threaded relief port, and reference the MB004B silencer option for compatibility.
The V64H-4GD-RMN complies with PED Category 0(S.E.P.) and Category 1 of the Pressure Equipment Directive 97/23/EC and carries CE marking. These certifications are critical for safe operation in European facilities, ensuring reliable protection against over-pressurisation and legal conformity for installation on processed air systems across industries.
Plan routine inspection of seals and elastomers, and consider the V64H-KIT service kit for scheduled maintenance. Longevity is supported by zinc body and bonnet materials, reducing replacement costs, while the optional service kit, silencers, and mounting hardware minimize downtime and extend asset life in automated plants.
