Pump Valve - 22x11x20

The red pump valve for Kränzle AYP and AQ (Ø22) is a component of the valve section in a high-pressure pump, used during service and refurbishment. A properly working valve ensures correct flow and tight sealing on the seat, which directly affects stable working pressure and smooth system operation.

MPN / reference: 42024
Weight: 0.001 kg
Dimensions / size: 24×27×24 mm
Diameter (Ø): 22

APPLICATION

Used in pressure pump servicing, including:

• replacing a valve-section component in AYP/AQ pumps,
• pump refurbishment when pressure drops and operation becomes unstable,
• repairs after operating with water containing deposits/particles (reduced valve sealing),
• periodic inspections when valve checks indicate wear or leakage.

SYMPTOMS - WHEN IT’S WORTH REPLACING

Typical symptoms of valve wear or leakage:

• drop in working pressure and noticeably weaker output,
• jet pulsation and pressure fluctuations during operation,
• difficulty maintaining stable parameters under load,
• unstable pump behavior after releasing the trigger (pressure “floating”),
• visible wear, contamination, or damage after disassembly.

HOW TO CHOOSE THE RIGHT PART

Valve selection must match the pump design and valve seats:

• by manufacturer MPN / reference: 42024,
• by parameters: Ø22 and 24×27×24 mm (as specified),
• by comparison with the removed valve: verify type, dimensions, and seating method.

Color helps identify the variant, but the reference number and dimensions should be the primary selection criteria.

COMPATIBILITY

Valve described as intended for Kränzle AYP and AQ pumps (red variant, Ø22).
For safe selection, confirm compatibility by MPN 42024 and the pump documentation/parts list (specification table). Selecting only by color without reference verification is not recommended.

Is “Ø22” enough to select the correct valve?|It’s an important parameter, but not the only one. The safest method is selecting by MPN 42024 and comparing with the removed part (type and dimensions), because similar pumps may have different versions.
Will replacing the valve fix pressure drop and pulsation?|Often yes, if a leaking or worn valve is the cause. Similar symptoms can also be caused by the nozzle, water filter, air ingress, or other pump components - it’s worth ruling these out before disassembly.
Can I use an aftermarket replacement instead of Kränzle?|Only if type, Ø22, dimensions, and intended use match exactly. An incorrect match usually results in poor sealing on the seat and reduced output, so use the MPN and pump specification as the reference point.
