Manual Valves : Diaphragm Valves

ASAHI Valves | Control Valves

When the diaphragm, which is connected via compressor to the valve stem, is pulled away from the bottom of the valve body, the fluid has a smooth, streamlined flow.

Diaphragm Valves Product List

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

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.

TRUE UNION DIAPHRAGM VALVE TYPE 14(15-50mm)[1/2-2inch]

Easy Maintenance

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.

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

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.

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.

DIAPHRAGM VALVE TYPE 72(200,250mm)[8,10inch]

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.
