⑪  不具合の原因と処置方法

 

 

Causes of defects and how to correct them

 

 

不具合現象 

予想される原因 

対策・処置 

エア操作で開閉しない 

エアが供給されていない 

エアを供給してください 

操作圧力が低い 

操作圧力を確認してください 

全閉にしても流体が流れる 

ダイヤフラムが摩耗している 

バルブを交換してください 

ダイヤフラム又は本体にキズがある 
バルブに異物が噛み込んでいる 

バルブから外部へ流体が漏れる 

継手が緩んでいる 

継手部を増締めしてください 

ハンチングが発生する 

使用条件(流体圧力・流量)が適切でない 

使用条件を見直してください 

 

Status 

Cause 

Corrective action 

The valve cannot be opened 
and closed by actuating. 

The pilot pressure is not applied. 

Apply the pilot pressure. 

The pilot pressure is low. 

Check the pilot pressure. 

Leakage in fully closed position. 

The diaphragm is abraded. 

Replace the valve. 

Flaw in the diaphragm or body. 
Foreign matter is caught in the valve. 

Outer leakage from the valve. 

The cap nuts are loose. 

Retighten the cap nuts. 

Hunting. 

Operating conditions(medium pressure, 
flow rate) are improper. 

Check the operating conditions. 

 
 

⑫  残材・廃材の処理方法   

How to manage debris and waste

 

 
 

 

 

廃棄する場合は必ず廃棄専門業者に渡してください。

 

(燃焼させた場合、有毒ガスが発生します)

 

 

 

For scrapping any material, be sure to hand it over to a waste management agent. 

Burning it will generate toxic gas.

 

注意  Caution
