Note: The torque figures shown are for a valve that is frequently operated at the maximum operating pressure. Valves that are subject to
long static periods, may require a greater break-out torque.
Safety information, installation and maintenance
For full details see the Installation and Maintenance Instructions supplied with the product.
Welding
Only the models that have connections designed for welding (SW, BW, Imperial Tube connections) should be welded. Valves with flanged
connections must not be welded to avoid damages to the valve and/or injury to personnel.
