Product catalog summary
Handling Instructions
When handling warm water gates, ensure to use the provided lifting lugs and avoid lifting by the valve bore to prevent damage. Verify that the crane can support the gate's weight and that the gate is securely fastened. Use soft straps for lifting during assembly and disassembly.

Safety Precautions
Personnel involved in handling and maintenance must be qualified and equipped with personal protective equipment such as gloves, safety shoes, glasses, and helmets. Ensure the working area is isolated and follow lockout/tagout procedures.

Assembly Instructions
Before installation, inspect the valve body and components for damage. Ensure the valve body and sealing are clean and undamaged. Check that the frame and guides are free of foreign material.

Maintenance Guidelines
The primary maintenance task is replacing the sealing rubber joints located on the sides and bottom of the gate. Regular inspections every six months are recommended, although the lifespan of the sealings depends on factors like pressure, temperature, and fluid composition.

Changing Side Sealings
To replace side sealings, remove the gate from the frame and place it on a clean surface. Remove the bolts and stainless steel flanges, then replace the damaged EPDM sealings. Ensure new sealings match the old ones in dimensions. Use a knock punch for precise hole creation. Reinstall the flanges and tighten the bolts.

Changing Bottom Sealings
Follow the same procedure as for side sealings. Apply high resistance glue on sealing contacts to prevent water leakage. Use Vaseline (not oil or grease) during assembly for smoother operation.

Vaseline Specifications
CMO uses Vaseline Filante with the following properties: Saybolt color 15, fusion point 60°C, viscosity at 100°C is 5, penetration at 25°C is 165, no silicon content, and complies with Farmacopea BP standards.

When handling this type of gates please pay attention to the following points: The valves are supplied with lifting lugs to be lifted. Do not lift the gate by the valve bore. This can cause damages on the seating surfaces and sealings. SAFETY WARNING Check that the crane is rated to carry the weight of the gate. Make sure that the gate is correctly secured. During the assembling and dismounting it is recommended to lift the gate with soft straps. > To avoid personal injury or damage to the property from the release of process fluid: - Those in charge of handling and maintenance of the gate must...

To avoid personal injury or damage to the property from the release of process fluid: - Those in charge of handling and maintenance of the valve must be qualified and trained in gate operations. - Use appropriate personal protection equipment (gloves, safety shoes, glasses, helmet). - Lock out and tag out. - Isolate the working area. The only maintenance required on this type of valve is to change the sealing rubber joints. Two are located on the sides of the gate (to make the tightness with the frame sliding plates) and the other ones located on the bottom of the gate (to make the tightness...

Note: It is important to apply high resistance glue (similar to Loctite brand) on the contacts between the sealings. This will provide a strong adhesion between then and avoid leakages of water between them. Note: During the assembling of the new sealing joint it is recommended to apply VaselineӔ on the sealing area to make the assembling easier and to provide and smooth operation of the valve (do not use oil, neither grease).
