Key features

Fire safe design

The Series 555/401 Softseal Valve is built with fire safety as a priority. It has been rigorously tested and approved to resist high temperatures, ensuring it remains leak-tight even in the event of a fire. This makes it an ideal choice for installations inside occupied buildings where fire risk is a key concern.

Softseal and metallic wedge

This product combines resilient seating with Donkin’s trusted metal wedge for long-term sealing. Its unique double-faced wedge design seals on both machined faces, incorporating nitrile seals that sit outside the gas flow when the valve is open. This not only enhances sealing effectiveness but also contributes to the valve’s long-term durability.

Easy operation

The low torque requirements of the product allow for safe, one-person operation without the risk of over-exertion. Its maintenance-free feature also means it is built to reduce downtime and provide lasting, dependable service.

Safety approvals

The valve has been tested and approved, and is therefore CE marked according to the Pressure Equipment Directive, Kitemarked to GIS/V7-1, and UKCA certified.
