W11026622 Water Inlet Valve Assembly: The Complete International Buyer's Guide to Water Inlet Valves and Pressure Relief Protection

The W11026622 water inlet valve assembly is a replacement water inlet valve used to control fill and shut-off in water-using appliances and hydronic systems. Buyers sourcing it internationally should confirm the OEM cross-reference, inlet/outlet connection sizes, and the pressure rating of the relief valve protecting the same circuit before ordering.

What is a W11026622 water inlet valve assembly?

A W11026622 water inlet valve assembly is a solenoid- or diaphragm-actuated valve that opens to admit water into an appliance or hydronic loop and closes to stop the fill. It is a service-replacement part, so the critical buying decision is dimensional and functional equivalence, not brand cosmetics.

In practice, the inlet valve is only one half of a safe water-fill circuit. The other half is the pressure relief valve that protects the same vessel or loop from overpressure. Brands such as APOLLO and Watts set the benchmark for that protection layer, and 3G Electric stocks both families alongside the inlet-valve categories our customers request.

Quotable definition

A water inlet valve assembly is a flow-control device that admits water into an appliance or hydronic circuit on command and seals closed when the fill is complete. In the W11026622 assembly, correct selection depends on connection size, supply pressure, and solenoid voltage/frequency compatibility with the host equipment.

How does a water inlet valve assembly work?

Water enters the valve body through the inlet port and is held back by a diaphragm or piston until the solenoid or actuator is energised. When the control board calls for fill, the actuator opens the seat and water flows to the outlet. On shut-off, spring and line pressure reseat the diaphragm to stop flow.

Because the valve sits on the pressurised side of the system, any failure of the relief valve upstream can expose the inlet valve to overpressure. That is why buyers should always verify the relief valve rating on the same circuit — for example a 20 psi, 40 psi, or 75 psi ASME Section XIII valve — before specifying a replacement inlet assembly.

W11026622 water inlet valve assembly specifications

The table below summarises the measurable attributes buyers should confirm. Values shown are typical for the inlet-valve category and for the relief valves 3G Electric stocks to protect the same circuit; always confirm against the OEM datasheet for your exact W11026622 variant.

Which relief valve should protect the W11026622 circuit?

Selection depends on the vessel or loop the inlet valve feeds. For hydronic heating boilers, an ASME Section IV valve is the usual choice; for hot water supply and storage, ASME Section XIII is standard. The set pressure must never exceed the vessel's maximum allowable working pressure.

For light-duty residential-style loops, a 20 psi or 40 psi valve is common. For commercial storage tanks and larger water heaters, 30 psi to 75 psi valves with 1-1/4 in to 2 in outlets are typical. Bronze bodies suit potable and hot water service; cast iron suits closed hydronic loops.

Types and applications in International markets

• Appliance inlet valves — washing machines, dishwashers, and ice makers; usually 3/4 in NPT with low-voltage solenoids.
• Hydronic fill valves — boiler and loop fill; paired with ASME Section IV relief valves.
• Hot water storage inlet assemblies — commercial water heaters; paired with ASME Section XIII relief valves.
• Export variants — 50 Hz and 60 Hz solenoid coils, plus region-specific thread forms and voltage options.

International buyers should confirm frequency (50 Hz vs 60 Hz), voltage, and thread standard before shipment, because a valve that fits mechanically may still fail electrically in a different market.

Selection criteria: how to choose a W11026622 water inlet valve assembly

1. Confirm the OEM cross-reference. Verify that W11026622 is the correct replacement for your appliance or system, not just a similar-looking valve.
2. Match connection size and thread form. Measure inlet and outlet; confirm NPT vs NPTF and male vs female.
3. Check supply pressure and relief rating. The relief valve set pressure must be at or below the vessel MAWP.
4. Specify voltage and frequency. State 50 Hz or 60 Hz and the coil voltage for your destination market.
5. Confirm body material and standard. Bronze for potable/hot water; iron for closed loops; ASME Section IV or XIII as applicable.
6. Plan for export documentation. Request commercial invoice, packing list, and certificate of origin as needed for your market.

Product selection ladder: relief valves to pair with the W11026622 circuit

The table below compares relief valves from 3G Electric's stock, arranged from light-duty to higher-capacity service. Use it to match the protection layer to the inlet valve circuit you are servicing.

Step up the ladder when the vessel size, outlet diameter, or required set pressure exceeds the light-duty valves. For boiler service, move to the APOLLO ASME Section IV bronze valves; for large commercial storage, move to the 1-1/4 in to 2 in Watts valves with higher flow capacity.

Frequently asked questions

What is the W11026622 water inlet valve assembly used for?

It is a replacement water inlet valve that controls fill and shut-off in water-using appliances and hydronic circuits. It is typically paired with a pressure relief valve on the same circuit to protect against overpressure. Confirm the OEM cross-reference and connection sizes before ordering.

How do I confirm the W11026622 is the right replacement?

Check the OEM cross-reference against your appliance or system manual, then measure inlet and outlet connections and confirm thread form. Verify solenoid voltage and frequency (50 Hz or 60 Hz) match your market. If in doubt, send photos and nameplate data to 3G Electric for confirmation.

What pressure relief valve should I pair with it?

Match the relief valve set pressure to the vessel's maximum allowable working pressure. Use ASME Section IV valves for heating boilers and ASME Section XIII for hot water supply. Common ratings are 20 psi, 30 psi, 40 psi, 75 psi, 94 psi, and 160 psi depending on the application.

Can 3G Electric supply the W11026622 internationally?

Yes. 3G Electric supplies internationally with incoterms-neutral terms and export documentation experience. Lead times depend on stock status and destination; request a quote with your required delivery date and we will confirm availability and shipping options.

Do I need a 50 Hz or 60 Hz variant?

It depends on your destination market's power supply. Specify the frequency and coil voltage when requesting a quote, because a valve that fits mechanically may not operate correctly on the wrong frequency. 3G Electric can advise on cross-market variants.

What is the difference between ASME Section IV and Section XIII relief valves?

ASME Section IV covers heating boilers, while ASME Section XIII covers hot water supply systems. The correct standard depends on the vessel being protected. Using the wrong standard can compromise compliance and safety, so confirm with your system documentation.
