Diaphragm Valve
The Poduct
OTTO diaphragm valve is designed to provide the industry with a valve of exceptional reliability and trouble free performance. The valve has its advantages in interchangeability of parts, variety in materials of construction and finally capital and recurring expenses.
Application
This is a general purpose valve with application in every industry. The streamlined body can take any type of lining and hence is suitable for all corrosive fluids.
Construction
Standard product is made in cast iron and the wear – out parts in non ferrous material for longer life. The Weir design ensures efficient closure at low stem loads and hence enchences diaphragm life. The diaphragm is reinforced with best quality synthetic fabric and manufactured to our specifications under our supervision.
Types < style="font-family: verdana;">
< style="font-family: verdana;">The valves are offered in different materials of construction for the body, anti-corrosive lining.
< style="font-family: verdana;">
< style="font-family: verdana;"> Operation
The valve is operated by means of handwheel provided on top. Being precision built, the valve requires moderate for leakproof closure.
Maintaince
The value needs light greasing through nipples provided for purpose. Depending on the type of liquid being replacement at pre-determined intervals. In case of diaphragms failure, the valve should be isolated and drained prior to opening the bonnet for replacement. It is not necessary to dismantle the valve from the line from this purpose.
