Valve Head for Cast-Iron Valves with Seal 5/4" Perfexim 01-500-0320-000

Valve Head for Cast-Iron Valves with Seal 5/4" Perfexim 01-500-0320-000 is a direct-replacement valve head designed for use with cast-iron valve bodies that accept a 5/4" connection. The unit includes an integrated sealing gasket to restore tightness and reliable operation when servicing or repairing heating, plumbing, or industrial cast-iron valve assemblies. The component is manufactured to match the geometry and sealing surface of compatible cast-iron valves, enabling straightforward installation during routine maintenance or part replacement.

Advantages

The valve head provides a precise fit for cast-iron valves with a 5/4" connection and comes with an integrated seal to reduce the need for separate gaskets. Its design focuses on restoring valve tightness and function without modification to the valve body. Using a direct-replacement component helps minimize downtime during maintenance and supports consistent sealing performance in heating and plumbing systems.

Suitable for

• Servicing and repairing cast-iron heating valves
• Replacement of worn valve heads in plumbing systems
• Industrial valve maintenance where 5/4" connections are used
• On-site maintenance teams restoring valve tightness and operation

Key specifications

• Connection size: 5/4" compatible with cast-iron valve bodies
• Includes integrated sealing gasket for immediate installation
• Design: direct-replacement valve head for cast-iron assemblies
• Application: heating, plumbing, and industrial valve systems

How to use

Isolate the section of the system and drain any residual fluid before disassembling the valve. Remove the existing valve head according to the valve manufacturer's service instructions, inspect the valve body seating surface for debris or damage, and clean as needed. Fit the replacement valve head with its integrated seal into the valve body, ensuring correct alignment with the seating surface, then reassemble the valve components and tighten to the recommended torque values. Refill and repressurize the system, then test for leaks and proper operation.

Usage recommendations

Use only on compatible cast-iron valve bodies sized for 5/4" connections. Inspect the valve body seat before installation and replace the valve head only after isolating and depressurizing the system. If the seating surface is damaged or corroded, repair or replace the valve body to ensure reliable sealing. Follow local safety and maintenance procedures when working on heating or plumbing systems.
