Dragonfly

Valve

The Dragonfly Valve is a leak-free valve without compromise. We have developed this technology to enable the safe operation of valves handling aggressive, explosive, or toxic media, as well as operations at cryogenic temperatures. Being leak-free provides a zero-emission solution, reducing the global warming impact of stem leakage whilst increasing process safety.

100% leak-free design

Our Dragonfly Valve mechanism is designed such that the potential gas leak paths found in traditional valves are eliminated, with fully sealed bodies preventing shaft leakage. The Dragonfly Valve is designed to be leak-free for life, preventing environmentally damaging gases reaching the atmosphere.

The future of flow

The more freely a gas or any fluid can flow, the lower the energy required to get it to the customer. We have not compromised the flow efficiency of our valve in order to increase its containment characteristics. The Dragonfly has market-leading “full-bore” flow characteristics for minimal energy consumption.

Optimised efficiency and minimised complexity

The Dragonfly’s proprietary operating mechanism adds only a single additional moving part into the valve design, and results in the absolute minimum force to open and close, allowing it to be operated with magnetic couplings and small and extremely efficient electric actuators.

The Dragonfly Valve and Dragonfly-E

The Dragonfly Valve is our original stemless valve platform, designed for highly demanding process conditions, including hydrogen and ammonia service. The Dragonfly Valve range spans sizes from 8 mm to 250 mm diameter, with operating pressures up to PN 400 (Class 2500) and customers can select the actuation approach that best suits their system.

Dragonfly‑E is the latest product within the Dragonfly family. It builds on the same proven stemless Dragonfly Valve mechanism, but with optimised, fully integrated electric actuation. The actuator is designed as part of the valve itself, delivering a compact, low‑power, electrically actuated solution optimised for speed, efficiency, and simplicity.

We don’t compromise

on Efficiency

Until today, if you wanted to ensure gas stayed in the pipe, you needed to add a serious complexity with multiple sealing methods or embedding actuation within the pipe. The Dragonfly Valve keeps it simple. We add just one extra moving part over a traditional ball valve to reduce torque requirements ten-fold, and then operate it with magnetic couplings which are an established technology in pumps. With this no-fuss design, the Dragonfly Valve is intuitive and familiar to operate and maintain.

The Dragonfly Valve provides the long wear life and excellent flow capacity of an eccentric ball valve, but can be actuated with the smallest quarter turn actuator. With such high flow and low torque requirements, the Dragonfly Valve can squeeze in where others can’t while still keeping gas in the pipe.
