CRYSTAL N400 series diaphragm valve provides high flow and high hydraulic performance in fluid and pressure control.

These durable valves are efficiently designed and constructed from advanced technology plastics, thus requiring very low maintenance.

Available in compatibility for different diameter connecter, all hydraulic and electric solenoids for all kinds of purpose.

TECHNICAL CHARACTERISTICS:

1. Low head-lose

2. Low Openg/Close pressure: 2-3m

3. 3-way control loop to guranetee the valve fully open

4. Hydraulic operation against water hammer, slow open/close

5. Easy maintenance and access to internal parts without removing the valve from the pipeline

6. Dirsct-sealing diaphragm valves with aid by spring, operated by line pressure

7. Standard 3/8”command water filter, 2 ports on body

8. Body and cover are all made of reinforced Nylon, solar radiation resistant

9. 304 S.S.T.spring

10. Galvanized steel fixing bolts, optional for SST for under-ground installation

11. NR diaphragm with Nylon net reinforced

12. VIC-4”connection, easy for installation and disamount.

13. Supporting connector of PVC: VIC4”-110mm Glue(internal), also Flange4”-VIC4”

14. Modular with pressure reducing/sustaining regulator, DC-latch,AC solenoids and Manual switch

15. PN10

APPLICATIONS:

WORKING PRINCIPLE:

3-WAY CONTROL LOOP (ELECTRIC SOLENOID MODE OR PRESSURE REGULATING MODE)

This 3-way control loop will control the water quantity into chamber between diaphragm

and cover through solenoid or regulating regulator, thus the open space can be adjusted, which the valve will be fully open/close or regulated space.

This 3-way loop can make the valve chamber drain 100%, then the head loss is minimum.

We also produce 4”Hydrant metal angle valve with VIC connection
