AVK Donkin Series 555/371 Ductile Iron Softseal Gate Valves PN4/7

PE tailed gate valve to GIS/V7-1 for Natural Gas. Pressure range: 7 Bar (100psig) with PE 100 Tails, 4 Bar (60psig) with PE 80 Tails. Temperature range: -10°C to +40°C

The Ductile Iron Series 555/371 Softseal Valve is a double faced, resilient seat, internal screw, full bore, PE ended Wedge Gate Valve. It is designed primarily for the isolation of natural gas when fused in line on a PE gas distribution system. Body and Bonnet are manufactured from ductile iron for extra strength.  Kitemark approval to GIS/V7: Part 1 and GIS/PL3

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.
