DIN Stainless Steel Welded Gate Valve

Description
KERUI’s DIN stainless steel welded gate valves permit high fluid flow with negligible friction loss. To maximize performance and lifespan, this kind of stainless steel gate valve is not designed for modulating fluid flow. This DIN valve is best used for cutting through sticky, dense petroleum liquids and creating a leak-proof seal when the gate is fully closed.

Application
DIN stainless steel welded gate valves are widely applied in the fields of tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy system, etc.

Advantages
1. The opening torque of this stainless steel gate valve is low, leading a long service life.
2. Valve body of DIN valves is cast in precision, having high corrosion resistance.
3. Valves’ surface is processed twice, so it is smooth and fine in appearance.
4. Valve discs are machined by CNC.
5. DIN stainless steel welded gate valves are convenient and fast to maintain.
6. Such stainless steel gate valves are guaranteed within 18 months.

Features
1. Minimum flow restriction.
2. Very low frequency of water hammer phenomenon.
3. Convenient to install and maintain. Easy to open and close.

Main Components
DIN stainless steel welded gate valve is mainly composed of valve body, wedge disc, bonnet, gland, bolts and nuts, gasket, etc.

Maintenance
1. Hand wheel, handle, and transmission structure of this stainless steel gate valve cannot be hoisted. And collision is prohibited.
2. Dual welded gate valves should be installed vertically, that’s to say, the stem is in vertical direction and handle wheel is at the top.
3. If DIN valves have by-pass valve, the by-pass valve should be open first to balance the pressure of entrance and exit.
4. Please install those stainless steel gate valves with transmission structure according to operating manual.
5. If DIN stainless steel welded gate valves are used frequently, please lubricate them at least once per month. And they should be maintained regularly.

Attention
1. Before installing DIN valves, please check valve body, sealing surface and other parts to avoid any dirt attachment.
2. Bolts at any connection joint should be fastened.
3. Check the packing part to ensure excellent sealing performance and ensure flexible opening.
4. Customers should pay attention to valve type, connection size and flowing direction of fluids, to guarantee consistency with the DIN stainless steel welded gate valve to be installed.
5. When installing, some space should be left for this stainless steel gate valve to actuate.
6. The connection of actuating device should be strictly conformed to circuit diagram.

Payment, Package and Transportation
Payment such as T/T, D/P, D/A, L/C is accepted. We deliver our DIN stainless steel welded gate valves by railway, sea, or airplane in standard wooden boxes.
