Resilient Seated 4 Inch Gate valve

4 inch gate valve Description

 A cast iron resilient seated 4 inch gate valve is a type of valve specifically designed for controlling the flow of fluids in pipelines. It is made from cast iron, which provides high strength and durability. The valve features a resilient seat, typically made from rubber or elastomer material, that ensures a tight seal when the valve is closed.

The gate valve has a wedge-shaped gate that moves up and down within the valve body to control the flow. When the valve is fully open, the gate is lifted completely out of the flow path, allowing for unrestricted flow. Conversely, when the valve is closed, the gate is lowered into position, creating a tight seal against the resilient seat, preventing any fluid from passing through.

The 4 inch size refers to the diameter of the valve's opening, which determines the flow capacity of the valve. This size is suitable for medium-sized pipelines where a moderate flow rate is required.

The valve typically has flanged ends, which allow for easy installation and connection to pipeline systems using bolts. The non-rising stem design eliminates the need for vertical space during operation, making it suitable for installations with limited headroom.

Cast iron resilient seated gate valves are commonly utilized in water distribution systems, sewage treatment plants, and various industrial applications. They offer advantages such as corrosion resistance, low maintenance requirements, and cost-effectiveness. With proper installation and maintenance, these valves can provide reliable service and long-lasting performance.

4 inch gate valve Specification:

4 inch gate valve Features:

      •   Cast Iron Construction: The valve body and gate disc are made of cast iron, which provides durability and corrosion resistance.

      •   Resilient Seating: The gate valve is equipped with a resilient seat, usually made of EPDM rubber or NBR, which ensures a tight seal and prevents leakage.

      •   Flanged Connection: The valve has flanged ends, allowing for easy installation and connection to pipelines.

      •   Handwheel or Gear Operation: The valve can be operated manually using a handwheel or with the help of a gear mechanism, providing ease of operation.

      •   Non-Rising Stem: The gate valve features a non-rising stem design, which means that the stem does not extend out of the valve body during operation. This makes it suitable for installations with limited space.

      •   ANSI Class 125 or 150 Pressure Rating: The valve is designed to withstand pressures up to ANSI Class 125 or 150, depending on the specific model and application.

      •   Suitable for Water and Other Non-Aggressive Fluids: Cast iron resilient seated gate valves are commonly used in water supply systems, wastewater treatment plants, irrigation systems, and other applications where non-aggressive fluids are being controlled.

      •   Operating Temperature Range: The valve can typically operate within a temperature range of -10°C to 80°C (14°F to 176°F), although this may vary depending on the specific design and materials used.

4 inch gate valve Advantages:

      •   Durability: Cast iron construction provides excellent strength and durability, making these valves suitable for heavy-duty applications.

      •   Corrosion Resistance: Cast iron gate valves are resistant to corrosion, which makes them ideal for use in water and wastewater systems.

      •   Tight Shut-Off: The resilient seat ensures a tight seal, preventing leakage and providing reliable shut-off.

      •   Low Maintenance: These valves generally require minimal maintenance due to their rugged construction and resilient seal design.

      •   Easy Installation: The flanged ends of the valve allow for easy installation and connections to pipelines.

      •   Versatility: Cast iron resilient seated gate valves are suitable for a wide range of applications, including water distribution systems, sewage treatment plants, and industrial processes.

      •   Non-Rising Stem Design: The non-rising stem design eliminates the need for vertical space, making these valves suitable for installations with limited headroom.

      •   Cost-Effective: Cast iron gate valves are generally more affordable compared to other materials, making them a cost-effective choice for many applications.

      •   Long Service Life: With proper installation and maintenance, cast iron resilient seated gate valves can provide a long service life, ensuring reliable operation over time.
