Pump Valve - 16x8x18

The red pump valve for Kränzle AP/AZ is a single component of a high-pressure pump’s valve section, used during maintenance and repairs. A properly working valve ensures correct water flow and stable pump operating parameters, so its condition directly affects pressure and jet stability.

MPN / reference: 41612
Weight: 0.001 kg
Dimensions / size: 16×8×18

APPLICATION

Used in Kränzle pump service work, including:

• replacing a valve in the pump suction/discharge section (valve-section repair),
• pump maintenance after operating with water containing deposits or particles (reduced sealing on the seat),
• pump refurbishment when performance drops and operation becomes uneven,
• periodic inspections in pressure pump service when valve checks indicate wear.
• SYMPTOMS – WHEN IT’S WORTH REPLACING

Typical symptoms of valve wear or leakage:

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

HOW TO CHOOSE THE RIGHT PART

Valve selection must match the pump design and valve seats:

• by manufacturer MPN / reference: 41612,
• by application: Kränzle AP/AZ pumps (red variant),
• by comparison with the removed valve: verify type, dimensions, and seating method.

Accurate fit is critical for valve-section tightness - even small differences can cause pressure drop or pulsation.

COMPATIBILITY

Valve described as intended for Kränzle AP/AZ pumps.
For safe selection, confirm compatibility by MPN 41612 and the pump technical data (parts list/specification). Selecting only by color without verifying the reference is not recommended.

[faq]

Is the red color enough to select the correct valve?|No. Color can help identify the variant, but the safest method is selecting by MPN 41612 and comparing with the removed part. Different versions may exist within one series.
Does it make sense to replace one valve, or is it better to replace the full set?|It depends on the condition of the remaining valves. If wear is even or the pump has high hours, service practice often considers replacing the full set. If only one valve is affected (e.g., mechanical damage), replacing a single part may be sufficient.
Can I use an aftermarket valve instead of the Kränzle part?|Only if type, dimensions, and intended use match exactly. Valves must seal properly on their seats; an incorrect match results in reduced output and unstable pressure. Use the MPN and pump specification as your reference point.
