The Series 555 Steel Softseal Valve is a double-faced, resilient seat, internal screw, clear bore wedge gate valve. Designed primarily for the isolation of high pressure natural gas, fitting into steel pipelines. Manufactured with the new Donkin PUR corrosion protection system, enabling burial without need for wrapping of the valve body.  To ensure full long term protection, flanges and bolts should be wrapped in line with industry guidelines. Manufactured and approved to specification GIS/V7:Part 1

The Donkin 555 softseal gas valves are manufactured with the tried and trusted Donkin metallic wedge used for over 50 years on the gas networks. A true wedge design, the gate seals on both machined faces with an embedded nitrile seal in each face which sit completely outside the flow of gas with the valve open.
• The design gives effective and long term sealing on closure and the closing torques remain relatively low over the valve’s design life.
• The low closing / breaking torque means operators don’t risk over exertion / injury. Can be easily closed by a single person with standard equipment.
• Negates the need for manual handling risk assessment.
