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 tignt 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. 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.
