Donkin Series 555 Cast Iron Gate Valves

Flanged Gate Valve to GIS/V7:Part 1. Pressure range: 7 Bar (100 PSIG). Temperature range: -10°C to +100°C

The Series 555/300-002 Softseal valve is a double-faced, resilient seat, internal screw, clear bore wedge gate valve. It is designed primarily for the isolation of sewage gas and wet/dirty gases.  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.
