4 inch Gate Valve
The dimension of a 4 inch gate valve is normally DN100.
The 4″ gate valve is a commonly used pipeline control device, featured with a compact structure and a light weight. It can be widely applied in fields such as water treatment, petrochemical industry, etc. When using it, it is necessary to select an appropriate nominal pressure and structural length according to the actual situation, and install and operate it strictly in accordance with the specification requirements.
Main features of the 4 inch gate valve.
- The stem of the 4 inch gate valve adopts T-head which is integral, This is much stronger than a threaded or welded stem and is less prone to high-pressure bending;
- The stuffing box is deep enough to ensure sufficient packing to keep the stem sealed for a long time. Standard installed stuffing box design requirements meet < 100ppm unorganized emissions requirements, the protection is in consistent with ISO 14001 certification;
- The handwheel design makes the valve easy to operate, the manual operation process uses to power up. Turbine drives, electric and pneumatic devices are also available;

The applications of 4 gate valve:
- Water Treatment Industry
In the fields of tap water supply and sewage disposal, gate valves are indispensable pipeline control devices. The normal working pressure of a 4 inch gate valve is generally within 1.6 MPa, making it suitable for the on-off control of medium and low pressure hydraulic pipelines. - Petrochemical Industry
In petrochemical enterprises, gate valves are widely used in every link of oil and gas transportation, storage and transportation systems, such as refining, distillation, cracking and other process procedures. The 4 inch gate valve not only has the characteristics of traditional gate valves, such as good sealing performance and small starting torque, but also features a compact structure and light weight. It can greatly reduce the equipment maintenance cost and tooling installation time. - Other Fields
The 4 inch gate valve can also be used for pipeline control in fields such as food, medicine, papermaking and metallurgy. Apart from achieving sealing through the gate plate on the sealing surface, the flow rate through the inner wall of a gate valve is smaller than that of a globe valve. This is also one of the advantages of gate valves when used for controlling dusty media.
How many turns to close a 4 inch gate valve?
To close a 4 gate valve, it needs 3 to 4 turns.
