Valve Head for Cast-Iron Valves with Seal 3/4" Perfexim 01-500-0200-000

Replacement valve head for cast-iron valves designed by Perfexim, compatible with 3/4" valve connections and supplied with an integrated seal to reduce the risk of leakage. This spare part is intended for repair and maintenance of heating and plumbing systems that use cast-iron valve bodies. The component restores valve function and re-establishes tight sealing in domestic and commercial installations without requiring full valve replacement.

Advantages

The valve head is manufactured to match the geometry and dimensions of cast-iron valve bodies and includes a built-in sealing element to minimize leaks. Its 3/4" connection size ensures compatibility with standard pipework and fittings used in heating and plumbing systems. The part reduces downtime during maintenance because it can be installed in place of a worn valve head, and the integrated seal simplifies assembly and improves reliability.

Suitable for

• Repair of cast-iron valves in residential heating systems
• Maintenance of plumbing installations in commercial buildings
• Restoring sealing function of valves showing leakage or loss of control
• Replacement of worn internal valve heads during routine servicing

Key specifications

• Connection size: 3/4" compatible with standard valve ports
• Material: designed for cast-iron valve bodies (mating material specified by manufacturer)
• Seal type: integrated sealing element supplied with the head
• Application: suitable for heating and plumbing systems
• Function: replacement valve head to restore flow control and sealing

How to use

Isolate the system and drain the section containing the valve before beginning work. Remove the existing valve head from the cast-iron valve body according to the valve manufacturer's instructions, inspect the valve seat and internal surfaces for debris or corrosion, and clean as necessary. Fit the replacement valve head ensuring the integrated seal is correctly positioned, then tighten to the recommended torque or mounting method specified for the valve body. Refill and repressurize the system, then check for correct operation and leak-tightness at the connection.

Usage recommendations

Use only after confirming compatibility with the specific cast-iron valve model and follow safety procedures for draining and repressurizing heating or plumbing systems. Perform a leak test after installation and replace the valve body if excessive corrosion or damage to the seat is found.
