12V 24V Underwater Solenoid Valves
Product introduction:
SLDF underwater solenoid valve is a common switching element in the automatic control system It is the core control equipment of music fountain. It is especially suitable for the waterway control of running spring and jumping spring. This valve is a direct acting solenoid valve working with medium pressure difference. It adopts diaphragm structure. SLDF series solenoid valves have the characteristics of rapid opening and closing, stable performance, convenient use, high reliability and long service life; SLDF series solenoid valve has strong anti pollution ability and can be used in rivers, lakes, seas and various artificial waters for a long time. Its superb performance is at the leading level in China.
2 Way normally closed 12V direct acting diaphragm waterproof brass and stainless steel solenoid valve widely used for fountain applications such as swimming pool, park fountain magnetic solenoid malve with Rubber, PTFE, NBR, EPDM soft seal, Armature Tube-Stainless Steel304, Plunger-Stainless Steel 430F, Stop – SS 403F, Springs -SS 304, Shading Rings -Stainless Steel 304. HKP has a IP68 waterproof solenoid coil which could used under water Fast acting, Open from 0 bar with large flow rate.
Underwater solenoid valve features:
* Direct lifting diaphragm construction
* Waterproof solenoid valve with compact design
* IP68 solenoid coil which could used in underwater
* High frequency, applied to low pressure system
* Application for swimming pool, square fountain

We supply Solenoid valves specifically designed for fountain application. These special valves come in Stainless Steel (SS304) and pure Brass bodies, along with a high quality waterproof solenoid coil.
How to use the underwater solenoid valves?
A: just open the power supply then it can work. When using, please strictly abide by various technical requirements, such as working voltage, action frequency, working pressure and operating temperature; During the commissioning of the whole machine, it is recommended to use the manual device for commissioning first, and then power on for commissioning.
How to install the underwater solenoid valves?
A: Install along the flow direction of the water pipe! It cannot be hung upside down or hung!
How to program solenoid valves?
A: suggestion like below -
Defer 0:02 Then OFF
If Outlet CL_Pump = OFF Then OFF
[Solenoid_2]
OSC 0:15/0:15/0:30 Then ON
Defer 0:02 Then OFF
If Outlet CL_Pump = OFF Then OFF
[Solenoid_3]
OSC 0:30/0:15/0:15 Then ON
Defer 0:02 Then OFF
If Outlet CL_Pump = OFF Then OFF
[Solenoid_4]
OSC 0:45/0:15/0:00 Then ON
Defer 0:02 Then OFF
Rotation is at 15 second intervals, but each solenoid stays open for 17 seconds, allowing a 2-second transition to avoid "slamming" the CL pump and piping. As you mentioned, If Feedx statements and maintenance shutdowns would be programmed on the outlet for the CL pump itself.
