Solenoid Valve for Wave Sequencer 1 1/2 Inch QCA Spas Current

QCA Spas solenoid valve for wave systems found in later model (after 2013) Paradise Ultra, Cozumel Ultra, St Maarten XL and other spas that use the wave sequencer.  This is model 21015GP2NP000M0-Q and is a 1 1/2" solenoid valve.

This complete solenoid is part of a 4 or 8 solenoid system that drives the wave function of the Wave Max and Ultra Lounge features.

Solenoid valves are electromechanically operated. When a current passes through the solenoid it is switched on and when no current is present it is switched off.  The solenoids are connected to the spa plumbing system and receive water flow from the jet pump through a manifold that divides up the water flow to different areas of the spa.

The task of this solenoid is to turn water flow off and on depending on what setting the sequencer is set at or what part of the dynamic sequencing program the spa is going through. 

Long service life and compact design make this a high quality component.

Be careful when replacing solenoid valves to assure that any internal plunger, should it fall out, is replaced the right way as they are directional.

Need a smaller 1" solenoid valve for an older model QCA Spa? We've go those too.

The plunger inside is referred to as the actuator.

This solenoid is found in many newer model QCA Spas built after 2013 that use the 1 1/2" size solenoid valves.

Older spas will use the 1" solenoid that we also offer.

SOLENOID Valve operation in the QCA Spa Wave System
The way a solenoid valve operates is as follows: When power is applied to the solenoid it lifts a plunger inside the solenoid opening a port allowing pressure to equalize across both sides of the internal diaphragm allowing water to flow through the valve. If debris is interfering with the plunger being able to seal off the port water will flow even though there is no power applied to the solenoid. If there is debris on the back side of the port restricting the port from opening all the way the flow will be reduced. Debris can be cleaned away by unscrewing the solenoid and cleaning the end of the plunger and the equalizing port. Be careful when removing the solenoid as the plunger is spring loaded.

Debris on the back side of the port can be caused by glue flakes lodged at the port. It can be removed by removing the screws that hold the valve halves together.
