A gate valve's straight, unobstructed path leads to minimal pressure loss through the valve.
A gate valve takes up a small amount of space along the length of the piping.
These valves work well with larger-diameter piping due to their simple construction. They are relatively easy to scale to larger sizes.
A gate valve's simple design results in the valve being relatively durable.
Gate valves operate slowly, reducing the possibility of water hammer in the system.
Knife valves are a specific type of parallel gate valve. They have a sharp edge on the bottom of the gate to shear entrained solids or separate slurries.
The through-conduit gate valves have a rectangular closure element. The closure has a circular opening equal to the full-area flow passageway of the gate valve; as the element is lowered the opening is exposed to the flow. Raising the element shuts off the flow. In this design the seating surface of the gate is in contact with the gate at all times.
Solid wedges are the most common because of their simplicity and strength. They can be installed in any position, are suitable for almost all fluids, and are practical for turbulent flow.
Flexible wedge gate valves are commonly used in steam systems. The disk is one piece with a cut around the perimeter to improve the ability to match error or change the angle between the seats. Different sizes, shapes, and depths are available.
Gate Valve Components
Body
The main pressure-retaining structure that houses the internal parts and connects to the piping system.
Bonnet
Attached to the body, it encloses the valve’s stem and forms a seal. Common types include bolted, union, and pressure seal bonnets.
Gate or Disc
The actual flow-blocking component that moves vertically to open or close the valve. Can be solid, flexible, or split.
Stem
Connects the actuator or handwheel to the gate, transmitting motion to open or close the valve.
Seat Rings
Provide the sealing interface between the gate and the body. Can be integral or replaceable.
Packing and Gland
Prevent leakage around the stem and are adjustable to maintain a tight seal.
Applications
Oil and Gas Industry
In oil and gas transmission pipelines, gate valves can withstand high pressure and long-term operation requirements. They are widely used in wellhead assemblies, transmission lines, and storage tank systems. Their resistance to high temperature and high pressure ensures safety in critical operations.
Chemical and Refining Plants
Chemical media are often corrosive or high-temperature fluids. Using gate valves made of stainless steel or special alloys effectively minimizes leakage risks. In addition, the full-bore design of gate valves helps maintain efficient material transport.
Power Industry (Thermal and Nuclear)
In boiler feedwater, steam transmission, and cooling systems, gate valves are among the mainstream choices due to their reliable sealing. They are particularly well-suited for high-temperature and high-pressure steam pipelines.
Municipal and Water Treatment Systems
Whether in urban water supply networks or wastewater treatment plants, gate valves are suitable for on/off control in large-diameter pipelines. They are especially common in underground pipelines, where their simple and durable design ensures reliable long-term buried operation.
