  • Page 4: Assembling Additional Modules

    ATTENTION! Welded ends valves: - Ensure compatibility of ends; clean valve and pipe ends carefully, tack-weld the valve on the pipe in four points on both end caps, putting trim away to prevent heat exposure when soft parts, if any, could be affected by heat. Once the welding process is finished, wait until system cools down before inserting the trim back. The installer should take the necessary precautions to prevent thermal stressing/ overheating the valve during welding process. ACTUATOR: - If the valve requires pneumatic, electric or hydraulic actuator, separate actuator Manual shall be also followed. To avoid unnecessary stress and risk of valve break, consider the weight and the relative position of actuator to evaluate its support. Make sure that the actuator is suitable for service particular requirements, valve adaptability, function needed, adequate torque for the valve, adequate speed, need for limit switches, etc. Contact our Techni- cal Department for advice. In case of actuator mounted, disconnect the energy supply before starting work. 5.2 Assembling additional modules Optional accessories (limit switches, extensions, etc.) that are supplied with valves must be fitted as required for their functions as shown in the system plan. 5.3 Requirements at the place of installation - Aggressive environmental conditions may reduce the life span of the product. Consider special construction/protective measures in such a case.
