valve

Cryatal 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 and electric solenoids for all kinds of purpose.

TECHNICAL CHARACTERISTICS:

1.Only for irrigation system under PN8

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

3. Hydraulic operation

4. Body made of uPVC, solar radiation resistant

5.Nylon Fiberglass Reinforced cover

6. 302 SST spring

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

8.NR diaphragm with screen reinforced

9. PVC gluing connection with PVC pipes, 4” valve 110mm inside and 140mm outside, 2” valve 63mm inside  and     75mm outside

10.Thread and flange connections can be selected according to order

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

12. Modular pilot, solenoid and switch can be easily added on valve body for different functions

APPLICATIONS:

1. Irrigation Systems (Field Valves-On ground)

2.SDI-subsurface drip irrigation system (Field valves-Underground Installation)

3.Bio fertigation system (marsh liquid) for bio-crops growing (Special request)

4. Anti-Frost Irrigation System With Underground Valves

5. Sewage Systems

6. Landscape

7. Greenhouse

8. Filteration

9.Animal feeding plants

10.Mining

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 pilot, 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.

FLEXIBLE CONNECTION:

With following connectors, you can easily change the valve connection to:

1.Bigger diameter with glue type

2.Smaller diameter with glue type

3.Female thread socket

4.Male thread adaptor

5.Flange
