ASAB DP23 - Replacement Outlet Valve Kit

Bring your DP23 back to clean, consistent delivery with the ASAB DP23 Outlet Valve Kit. The outlet valve is a critical sealing point in the fluid section—when it’s worn or contaminated you’ll typically see pulsing, pressure instability, poor shut-off behaviour, and a spray pattern that won’t stay consistent. This kit restores proper outlet sealing so the pump can hold pressure, smooth out the stroke, and maintain steady flow at the gun.

Ideal for scheduled servicing or when you’re chasing faults like pressure drop under load, inconsistent fan, spitting, or ongoing pulsation despite a clean tip and good suction setup.

Key benefits

• Restores stable pressure and smoother spray output

• Helps eliminate pulsing, pressure loss, and poor shut-off caused by outlet leakage

• Improves pump efficiency and consistency under load

• Ideal for preventative maintenance to reduce downtime and protect downstream components

What’s Included

Kit contents can vary slightly by revision, but typically includes the core outlet valve service components, such as:

• Outlet ball (where applicable)

• Outlet seat / cage (where applicable)

• O-rings / seals for the outlet valve assembly

• Retainers / gaskets required for correct reassembly (as applicable)

Safety Check
Before disassembly: fully depressurise the fluid system, isolate/bleed the air supply, and confirm the gauge reads zero. Wear eye protection and gloves—trapped pressure in the wet end can release suddenly if fittings are loosened in the wrong order.
