Flange-connected cast iron rising stem gate valve with copper seal, used as an opening and closing device for water and oil pipelines.

Product description

The gate valve is a valve device that realizes the on-off control of pipeline media through the lifting movement of the closing element (gate) along the vertical direction of the pipeline centerline. As the most widely used cut-off valve in industrial pipeline systems, its structural design is centered on the "straight channel + parallel sealing surface" to ensure the high efficiency of medium flow and the tightness of cut-off.

Cast steel is a type of steel formed by casting process. With its high strength, corrosion resistance, and excellent mechanical properties, it is mainly used to control the flow rate, pressure, and temperature of industrial pipelines, playing a core role in the field of automated production.

Technical Description of Cast Steel Gate Valves (Optimized English Version)

1. Low Flow Resistance
   Cast iron gate valves have a straight-through channel design that minimizes fluid resistance compared to globe valves, which reduces pressure losses by up to 80%, making them ideal for long distance piping systems.
2. Minimized Seal Surface Erosion
    protect against medium erosion.  Test data shows ≤0.01mm/year wear under normal operating conditions, ensuring prolonged service life in abrasive media applications.
3. Compact Structure & Effortless Operation
   Engineered with a wedge-type gate and precision-machined stem, these valves offer 30% lower operating torque than conventional designs. The compact body reduces installation space by 20%, suitable for tight-fit industrial environments.
4. Unrestricted Flow Direction
   Designed for bi-directional flow, the valve imposes no flow direction constraints.  It maintains laminar flow profiles without causing turbulence or pressure drop, ensuring stable medium transport.
5. Bi-Directional Installation Flexibility
   With identical flow characteristics in both directions, the valve allows versatile installation orientations (horizontal/vertical). This eliminates orientation errors and reduces installation time by 50% compared to unidirectional valves.
6. Shortened Structure & Diverse High-Performance Materials
   The streamlined body design shortens the manufacturing process by 30%. Available materials include:

Product features:

1. Fluid resistance is small, sealing surface by medium erosion and erosion.

2. Easy operation of open and close.

3. Medium flow is not restricted, no turbulence, no pressure reduction.

4. Simple shape, short structural length, mature manufacturing control and wide application.
