The Excelon design enables in-line installation or modular expansion with other Excelon products, delivering installation flexibility and space efficiency. This translates to reduced system footprint and simpler upgrades in automated lines and OEM machinery. The push-to-lock adjusting knob with tamper-resistant accessory prevents accidental changes on busy factory floors, reducing unplanned downtime and maintaining consistent performance. With an outlet pressure adjustment range of 0.3 to 10 bar and a maximum inlet pressure of 10 bar, the valve provides precise control that protects downstream equipment and minimizes energy losses during relief events. The device uses a zinc body with an acetal bonnet and knob, and neoprene elastomers, delivering durable performance in demanding environments while resisting typical wear. Compact dimensions (49 mm height, 98 mm length, 51 mm width) and a 0.33 kg weight simplify mounting in tight enclosures. PED categories 0 and 1 compliance reinforces regulatory acceptance across European markets and end-user safety expectations. A full spectrum of accessories and mountings, including Quietaire MB002B silencer and mounting brackets 4224-50 and 74316-50, support easy integration and quiet operation in noisy industrial settings. This combination delivers measurable business value through improved reliability, reduced maintenance, and faster install cycles in modern pneumatic systems.

FAQs
The V72G-2GK-NMN is designed for flexible integration within the Excelon family, supporting in-line installation or modular additions with other Excelon modules. It uses standard G1/4 port connections and offers compatible mounting options such as the Universal Bracket (4224-50) and Neck Mounting Bracket (74316-50). Optional accessories like the Quietaire MB002B silencer further optimize installation for noise-sensitive environments.
Key parameters include medium (compressed air), maximum inlet pressure of 10 bar, and outlet pressure adjustment from 0.3 to 10 bar. The gauge port is Rc1/8, enabling monitoring, and the operating temperature range is -34 to 65 °C (-30 to 150 °F). The port size is G1/4, with a compact footprint (49 mm high, 98 mm long, 51 mm wide) and a weight of 0.33 kg.
Yes. The valve complies with PED 97/23/EC categories 0 and 1, providing regulatory confidence for safe operation and CE-related considerations. This makes it suitable for European equipment and automation projects that require compliant pressure-relief solutions.
The push-to-lock adjusting knob, complemented by a tamper-resistant accessory, minimizes the risk of unintended pressure changes due to vibration or accidental contact. This ensures stable relief settings, reduces maintenance interruptions, and supports consistent performance across production lines.
Expect improved equipment protection and reduced downtime due to accurate, stable relief performance. Durable materials (zinc body, acetal components, neoprene elastomers) and inline/modular installation ease retrofit projects, lowering installation time and service overhead while extending the life of downstream pneumatic equipment.
