Cast steel gate valves are widely used industrial valves designed for reliable on-off control of fluid flow in pipelines. Known for their strength, durability, and stable sealing performance, cast steel gate valves are commonly installed in high-pressure and high-temperature systems where safety and long service life are required.
Manufactured in accordance with international standards such as API 600 and API 6D, cast steel gate valves are a dependable solution for critical process systems across multiple industries.
A cast steel gate valve is a linear-motion valve that uses a gate (wedge or slab) to start or stop the flow of media. When fully open, the gate is completely lifted out of the flow path, resulting in minimal pressure loss. When fully closed, it provides tight shut-off, making it suitable for isolation applications.
Compared with ductile iron or forged valves, cast steel gate valves offer higher mechanical strength and better performance under demanding pressure class and temperature conditions.
Cast steel gate valves are available in different body materials to suit various media and environments:
The availability of both steel gate valves and stainless steel variants allows users to select the optimal body material based on operating conditions and media characteristics.
Wedge gate valves are designed and manufactured according to API 600 and GB/T 12234 standards. They are widely used for isolation in pipelines where tight shut-off is required.
Key features include:
Slab gate valves are designed according to API 6D and GB/T 19672, commonly used in oil and gas transmission pipelines.
Key features include:
Cast steel gate valves are designed to handle a wide pressure class range, from low-pressure systems to ultra-high-pressure pipelines. Their cast steel construction ensures excellent resistance to deformation, making them reliable under fluctuating pressure and temperature conditions.
Cast steel gate valves are commonly used in:
Their robust structure, dependable shut-off performance, and wide material selection make them ideal for critical isolation applications.
Cast steel gate valves are an essential component in modern industrial piping systems. Whether manufactured in carbon steel for strength or stainless steel for corrosion resistance, these valves provide stable performance, long service life, and dependable isolation across diverse applications. With multiple body materials, pressure classes, and design standards available, cast steel gate valves remain a trusted choice for demanding industrial environments.
