Description
To maximize performance and lifespan, our API flanged stainless steel bellows seal gate valve is not designed for modulating fluid flow. Instead, this kind of flanged gate valve is best used for cutting through sticky and dense petroleum liquids, permitting and preventing high fluid flow but with negligible friction loss.
Application
Stainless steel bellows seal gate valves are widely applied in such pipelines in the fields of tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy system, etc.
Features
1. Easy to open and close, and convenient to install.
2. Very low frequency of water hammer phenomenon.
3. Low opening torque.
4. High corrosion resistance.
5. 18 months’ free maintenance.
6. API / CE certified.
Main Components
Stainless steel bellows seal gate valve is mainly composed of valve body, wedge disc, bonnet, gland, bellows, bolts and nuts, gasket, etc.
Attention
1. Before installing this flanged gate valve, please check valve body, sealing surface and other parts to avoid any dirt attachment.
2. The installing position, height and the direction of entrance and exit should be complied with design specifications.
3. Bolts at any connection joint should be fastened.
4. When choosing stainless steel bellows seal gate valves, customers should pay more attention to the working pressure and temperature, sealing performance, diameter, structure, connection size and medium involved.
Maintenance
1. Dual flanged gate valves should be installed vertically, that’s to say, the stem is in vertical direction and handle wheel is at the top.
2. If by-pass valve is combined with such API valves, it should be open first to balance the entrance and exit’s pressure and reduce the opening force.
3. If such flanged gate valves are used frequently, please lubricate them at least once per month. And they should be maintained regularly.
Payment, Package and Transportation
We accept such payments as T/T, D/P, D/A, or L/C. Our API stainless steel bellows seal gate valves will be packed in standard wooden boxes and delivered by railway, sea, or airplane.
