Donkin DUCTILE IRON/POLYETHELENE SOFTSEAL VALVE PN4/7

PE Ended Gate Valve to GIS/V7-1 and GIS/PL3. Temperature -10 ºC to + 40 ºC. Pressure range: 7 Bar (100psig) with PE 100 Tails, 4 Bar (60psig) with PE 80 Tails.

The Series 555/371 PE 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 and manufactured gas underground when fused in line on a PE main distribution system and comes with the new Donkin PUR coating system which allows the valve to be buried without further protection. 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.
