When it comes to fluid control systems in industrial applications, industrial gate valves remain one of the most trusted and widely used valve types. Designed for full open or full close operations, these valves offer low-pressure drops, high flow rates, and a tight seal, making them essential across various industries.
D & D Valve and Engineering Supplies is proud to be one of South Africa’s leading suppliers of high-quality industrial valves, including a full range of gate valves designed for reliability, durability, and performance. Whether managing a large-scale operation or a specialised process, our industrial gate valves are engineered to meet demanding industry standards.
What Are Industrial Gate Valves?
Industrial gate valves are linear motion valves used primarily to start or stop fluid flow. Unlike other valve types, they are not designed to regulate flow but rather to allow unrestricted passage or complete shutoff. The flow path is unobstructed when the gate is lifted, enabling minimal pressure drop and maximum efficiency.
Key Features of Industrial Gate Valves
- Bi-directional flow capability
- Minimal flow restriction when fully open
- Excellent shutoff performance
- Available in a wide range of sizes, pressure ratings, and materials
Their robust design and functionality make them ideal for use in high-pressure, high-temperature applications across the oil and gas, mining, water treatment, chemical processing, and power generation industries.
Applications of Industrial Gate Valves
Our industrial gate valves are suitable for a wide range of industrial processes, including:
- Pipeline shutoff systems
- Water and wastewater treatment
- Chemical and petrochemical processing
- Steam and gas distribution
- Oil and fuel transfer systems
- Mining and mineral processing
Whether you require valves for corrosive environments, high-pressure steam lines, or abrasive slurries, D & D Valve and Engineering Supplies has the right solution.
Our Range of Industrial Gate Valves
D & D Valve and Engineering Supplies offers a broad inventory of gate valves tailored to your operational needs, including:
- Rising Stem Gate Valves: The valve position is easily indicated by a stem that moves up and down with the gate.
- Non-Rising Stem Gate Valves: These are ideal for tight spaces, where the stem remains stationary as the gate moves internally.
- Solid Wedge Gate Valves: Designed for strength and stability, suitable for steam and high-pressure systems.
- Flexible Wedge Gate Valves: Offers better sealing and resistance to thermal binding or pipeline movement.
- Split Wedge Gate Valves: Compensates for seat distortion and thermal expansion, ensuring tight shutoff.
- Knife Gate Valves: Ideal for handling slurries, viscous fluids, and pulp applications, particularly in mining and paper industries.

FAQs – Industrial Gate Valves
What is the primary function of an industrial gate valve?
Industrial gate valves are used to start or stop the flow of fluids in a system. When open, they provide a full bore, resulting in low friction loss, and when closed, they form a tight seal.
Can gate valves be used to regulate flow?
No. Gate valves are not designed for throttling. Using them to control flow can damage them and reduce their lifespan.
What industries use industrial gate valves?
Due to their durability and effective shutoff capabilities, they are widely used in the oil and gas, chemical processing, power generation, water treatment, and mining industries.
Are your gate valves pressure-rated?
Yes, we stock valves in a range of pressure classes, including PN and ANSI standards, to suit various industrial applications.
Do you supply knife gate valves for slurry applications?
Yes, we stock a range of knife gate valves designed explicitly for abrasive and viscous fluids common in mining and wastewater industries.
Can I get technical support for valve selection?
Absolutely. Our experienced team is here to help you choose the correct gate valve based on your system requirements, pressure conditions, and media compatibility.
