Express Valve Services Ltd provide a long established and proven range of high quality fabricated  Stoplogs for the Isolation and Control applications of Water Supply, Wastewater, Tidal, Hydropower, Flood and Irrigation Industries.

Stop Logs are suitable for isolation duties and weiring applications where single piece handstops would be too heavy to lift or where multiple door sections are required. Stop logs are only suitable for water pressures up to the height of the top log. Special fixing arrangements can be accommodated.

Stoplogs are typically long rectangular beams (logs) that are placed on top of each other within a retaining frame, dependent on the control level of the liquid required. Logs are either removed manually or via suitable lifting structures.

Utilizing our in house design and production facilities, Express Valve Services Ltd provides a comprehensive package of flow control solutions to service quality, cost and availability.

EVS Stoplogs are available from aperture of 500mm – 3000mm (larger/rectangular upon request) meeting all operating heads, civil structure fixing including all associated lifting equipment and Installation.

For sizes below 500mm wide, please refer to EVS Handstops for consideration.
