Tapco Zur P4000E Diaphragm Control Cartridge

Product Description

The TAPCO ZUR P4000E is a diaphragm control cartridge designed for use in gas control valve assemblies. This component regulates gas flow by using a flexible diaphragm mechanism to open, close, or modulate the valve based on pressure differential or control signal input. It is a serviceable internal component installed by licensed gas technicians and plumbers working on residential or light commercial heating equipment, including gas furnaces, boilers, and water heaters. The cartridge replaces a worn or failed diaphragm control element within an existing valve body, restoring proper flow regulation without replacing the entire valve assembly.

The ZUR P4000E cartridge is suited for gas valve service applications where the control diaphragm has failed due to age, chemical exposure, or mechanical wear. It is installed during valve repair or overhaul procedures and is appropriate for service work on gas-fired heating systems. Technicians performing gas valve rebuilds or scheduled maintenance will find this cartridge applicable in scenarios where the original diaphragm element requires replacement.

Key Features

• Diaphragm-based flow control mechanism for reliable gas valve regulation
• Designed as a serviceable cartridge replacement within compatible valve bodies
• Allows valve repair without full assembly replacement, reducing service cost
• Appropriate for gas valve overhaul on residential and light commercial heating equipment

Compatibility

Designed as an OEM-style replacement diaphragm control cartridge for compatible gas control valve assemblies. Verify fitment against the existing valve model before installation.

Installation Notes

Installation should be performed by a licensed gas technician or plumber in accordance with applicable local codes and the IFGC. Shut off the gas supply and depressurize the valve assembly completely before disassembly. Inspect the valve body for damage or contamination before installing the new cartridge. Follow the valve manufacturer's service documentation for proper cartridge seating and reassembly procedures.
