1. JD745X Diaphragm Type Multifunctional Pump Control Value |
|
| |
 |
|
| |
Product introduction: |
|
| |
Diaphragm type multifunctional pump control valve is installed at the outlet of pump in high building water supplying system and other to prevent backward flow, water-hammering, water-hitting. The valve have the function of the following valve :motorized valve, non return valve
and water-hammering eliminator and can improve the safety in the system. The valve have slow-open,quick-close and slow-close function
to prevent water-hammering when open or close pump.Only push the button for closing or opening pump and the valve can run according
to the pump's operation procedure with large flow and little pressure loss.JD745X diaphragm type multifunctional pump control valve is for
DN 600 or less valve. |

2.F745X Diaphragm Type Remote Control Float Valve |
|
| |
 |
|
| |
Product introduction: |
|
| |
Diaphragm type remote control float valve is a hydraulically-operated valve with much function. It is installed at the inlet of spool or water
tower.When the water level reach to the setting,the main valve controlled by the pilot valve,close and stop supplying water;when the water
level falls downward,
the main valve controlled by the pilot valve,opens and supplies water to the spool.The water level is controlled precisely and is not
interfered by the water pressure.Floating ball remote control valve can be installed freely according to the spool's height and use
space.It is easy to maintain and to inspect the valve.The valve is liable,of high strength and of smooth action and is fot DN450 or less valve. |

3.YX741 Diaphragm Type Adjustable Pressure Reducing/Sustaining Valve |
|
| |
 |
|
| |
Product introduction: |
|
| |
Diaphragm type adjustable pressure reducing/sustaining valve is installed in feeding/draining water system in high building to reduce
the inlet pressure required pressure.The valve ensure outlet pressure stay in the setting valve stably on its own energy,
namely the outlet pressure does not change owing to the inlet pressure's and flow's change.There is self-cleaning filtering mesh installed
at the valve control system's inlet not to let the great specific gravity and large diameter particle flow in to the system and ensure the
system is unimpeded.The valve acts quickly and has a long life |

4.AX742 diaphragm type pressure relieving\sustaining valve |
|
| |
 |
|
| |
Product introduction: |
|
| |
Diaphragm type pressure relieving/sustaining valve is installed in feeding water system's pipeline in high building,fire protection and
other.When the line pressure is bey ond the valve's setting pressure,the valve automatically opens to relieve pressure to ensure the
pipeline is safe,and at the same time it can be used as pressure sustaining valve to ensure the upstream pressure is enough.
The valve can provide and unchanged setting pressure and once the pressure is over,the valve opens quickly andrelieve the over pressure.
The valve can close stably and smoothly and prevent the pressure repercussions |
