Diaphragm valves offer many combinations of body and elastomeric diaphragm materials. The valve design is abrasion resistant and non-clogging. When the diaphragm, which is connected to the stem of the valve by a compressor, is pulled away from the bottom of the valve body or weir, the path of the fluid has smooth, streamlined flow. Slurries at low pressure that would normally clog most other valve designs easily pass through a diaphragm valve. The bonnet and working parts are completely isolated from the line fluid and only the body diaphragm materials must be considered for service compatibility. The valve is a top-entry design, allowing in-line maintenance. The valve is suitable for throttling and ON/OFF service in applications ranging from water treatment to chemical abrasion processes. Diaphragm valves are operated manually, electrically, or pneumatically.

The valve body can be removed from the pipe line by loosening the union nuts at both its ends.

Bottom Stand for Easy Support

Having a new bottom stand with an insert hole, DIAPHRAGM VALVE TYPE 14 helps support the piping. The valve is also provided with a flange stand to increase installation safety.

 


ASAHI AV Diaphragm Valve Type-14 Flanged

DIAPHRAGM VALVE TYPE 14 (15-100mm)[1/2-4inch]

Size:

15 – 100mm

1/2" – 4"

Standard:

JIS, ANSI, DIN

 

Body Materials:

PVC,CPVC,PP and PVDF

 

Body Type:

Flanged

Diaphragm Materials:

EPDM & 3-Layer EPDM/PVDF/PTFE
Nitrile & FKM also available

Applications:

Throttling, slurry lines, chemical processing, bleach plants, aquariums, mining, water treatment, landfills, swimming pools, semiconductor manufacturing

Easier Maintenance

A bayonet mechanism, provided between the diaphragm and compressor, allows the diaphragm to be replaced easily.

Bottom Stand for Easy Support

Having a new bottom stand with an insert hole, DIAPHRAGM VALVE TYPE 14 helps support the piping. The valve is also provided with a flange stand to increase installation safety.

Excellent Sealing Property

The DIAPHRAGM VALVE TYPE 14 uses a high quality rubber material,exhibiting lower compressive strain, for its diaphragm and cushion,resulting in optimum sealing performance.

Tight Seal at Low Torque

Using dynamic analysis by CAE, DIAPHRAGM VALVE TYPE 14 is designed so that pressure is distributed evenly.This design allows the hand wheel torque be reduced and maintain shutt off at low torque.

Built-in Travel Stop

DIAPHRAGM VALVE TYPE 14 contains a revolutionary travel stop mechanism protecting the diaphragm.

Visual Indicator

A color indicator clearly shows whether the valve is fully open, half open, or fully closed. Because the indicator enters the handle,going out of view when the valve fully closes, the operator can know at glance valve position.


ASAHI AV Diaphragm Valve Type-15

 

DIAPHRAGM VALVE TYPE 15(125,150mm)[5,6inch]

Size:

125 – 150mm

5" – 6"

EPDM & 3-Layer EPDM/PVDF/PTFE
Nitrile also available

 

Applications:

Throttling, slurry lines, chemical processing, bleach plants, aquariums, mining, water treatment, landfills, swimming pools, semiconductor manufacturing

Easier to operate

In order to reduce frictional force, material and shape of sliding parts are redesigned. Also improved hand wheel design allows for easy operation.

Improved outside sealing ability

By means of 3D CAD/CAE analysis, Type 15 diaphragm valve has increased body thickness. ln addition, usnig the elastomer that has high impact resilience, the sealing ability of valve is improved against high temperature changes.

Applications:

Throttling, slurry lines, chemical processing, bleach plants, aquariums, mining, water treatment, landfills, swimming pools, semiconductor manufacturing

Sealed Bonnet

Having a sealed bonnet with an O-ring, prevents rain water or external atmosphere from entering the bonnet, DIAPHRAGM VALVE TYPE 72 can be safelly used outdoors.

Sealed Indicator

Because a clear indicator gauge protects the exposed metallic part on top of the stem against atmosphere, corrosive gas or fluid does not of the valve.

Position Indication

The position indicator also shows the degree of the valve position.
