INNOVATIVE FEATURES

 

With this model Asahi has further improved its diaphragm valves. The diaphragm valves Type 14 are produced in PVC, C-PVC, PP, PVDF,
with gaskets in EPDM, FPM, PTFE and other. Dimensions are from DN 15 to DN 100.
The connections can be flanged UNI/DIN PN10 and ANSI 150 Lb or with sockets or threaded unions or spigot.

 

For larger dimensions the following models can be used: Type 15 for DN 125 and DN 150, Type 72 for DN 200 and DN 250.
The features of the diaphragm valves have been improved with the new design Type 14.

Here follow the new characteristics:

- Higher thickness of the flanged jointing between body and bonnet and better rubber materials of the diaphragm studied for an excellent sealing performance.

- Flow channel design to prevent the swirl and the separation of the fluid at downstream side.

- Design based on ergonomics assures excellent operation and piping.

- Bayonet connection to enable the diaphragm to be set easily by a 90 rotation.

- Bottom stand and flange stands to allow the valve to be installed easily and safety.

  As all the Asahi diaphragm valves, the gear is completely isolated from the fluid by the diaphragm. The top of the stem is protected for atmosphere by a polycarbonate cap. So, the valves are completely corrosion resistant within the valve and outside. In opening and closing the valve, the red stopper under the clear polycarbonate gauge cover indicates the position. The stopper prevents the diaphragm from overtightening and consequent damage. Asahi diaphragm valves are especially designed to resist high pressure for not only plastic pipes, but also lined iron and other metallic pipes.
