Gate valves are a type of valve that uses a gate for controlling the flow of the fluid present in the system. These valves have plenty of industrial applications due to several beneficial features they offer. The durability and reliability of these valves are fairly known in the industry. Gate valves consist of different types, such as Knife Gate Valves, Metal-to-Metal Sealing Gate Valves, and Rubber Wedge Gate Valves. Although these three types are provided at YasminTrading, there are more types of gate valves, such as Parallel Slide Gate Valves, Expanding Gate Valves, Double Disc Gate Valves, and Triple Offset Butterfly Valves. These types differ in size, pressure rating, temperature range, and application.

What is a Gate Valve?

Gate valves are a type of valve. They are called so because they use a gate to control the fluid flow through the entire piping system. According to Hawle, they can also use a wedge-shaped disc to control the flow of the fluid. Gate valves have some common and popular applications due to their benefits.

Applications of Gate Valves

Referring to AVK Valves, gate valves can be applied in various environments and conditions. The list of applications you can see below are some of the most common ones used for fluid control solutions.  
  • Gate valves can be applied as isolation valves, specifically in oil and gas pipelines.
  • These valves are generally used in HVAC systems. These are some heavy-duty gate valves used to control the chilled water flow in the system.
  • Gate valves are primary shut-off valves which are used in water and gas distribution systems.
  • In steam and condensate systems, gate valves play the role of control valves.
  • Gate valves are crucial in fire protection systems. These valves are used in fire sprinkler systems to control the water flow.

Benefits of Gate Valves

Gate valves offer various benefits, which is why they have so many applications. Gate valves are durable sealing valves and are also considered reliable valves. Some more popular benefits they own are found below.  
  • Gate valves shall be used in both entirely open and entirely closed positions.
  • They support both liquid and gas services.
  • Durability is a main feature of these valves. They withstand high pressure and different temperature changes.
  • Reliability is one of the most well-known benefits of gate valves. Reliable gate valves can be used in several different projects.
  • Gate valves provide a perfect shut-off. This makes them durable sealing valves, providing a leak-proof condition.
  • Easy maintenance is an essential benefit of these valves. This reduces downtime and costs over time.

What Are the Types of Gate Valves Available at YasminTrading?

At YasminTrading, you can find several different types of gate valves. We are an industrial valve supplier, making sure you get to use the best-fitting material for your projects. There are some specific types of gate valves that we can provide you with the best of these types. Here are some of the most practical ones.

Knife Gate Valve

A knife gate valve is one of the most practical types of gate valve. This type of gate valve works with a sharpened blade or a knife. The working mechanism is that this sharp blade cuts through fibrous media. The fibrous or thick media can be wastewater or any other type of viscous fluid.  
  • Knife gate valves can operate in different ways, such as manually, electrically, or pneumatically.
  • This type of gate valve is normally used in conditions where other types of gate valves would get damaged or clogged.
  • The knife is often made out of materials such as ceramic or stainless steel.
  • Knife gate valves are mainly used in large-scale industries, such as chemical processing and mining.
  • These gate valves are able to perfectly handle high pressure and a wide range of temperatures.
  • Knife gate valves are usually used for larger pipe sizes. The pipe size is normally more than 2 inches in diameter.

Metal-to-Metal Sealing Gate Valve

Metal-to-metal sealing gate valves use a metal-to-metal seal, as the name indicates. This type of gate valve perfectly prevents any risk of leakage. The metal-to-metal seal is mostly used in environments with high pressure and high temperature. This gate valve seals the gate and seat.  
  • Metal-to-metal sealing gate valves are applied when preventing leakage is critical.
  • This type of gate valve creates a suitable condition for bi-directional and unidirectional flow.
  • They typically show high resistance to wear and tear.
  • Metal-to-metal sealing gate valve is able to handle a good range of fluids, including corrosive and abrasive media.
  • These valves normally need much less maintenance requirements compared to some other types.
  • They can be designed for several different pressure ratings, including Class150 to Class2500.

Rubber Wedge Gate Valve

A rubber wedge gate valve is another type of gate valve. This type works with a rubber-lined wedge-shaped gate. This component works as the closing element in the system. Rubber wedge gate valves are typically used in wastewater treatment, fire protection systems, and drinking water supply.  
  • The rubber lining precisely prevents damage and leakage caused by impurities being lodged between the gate and seal.
  • There are various options for wedge lining materials, such as natural rubber, nitrile rubber, and EPDM.
  • Rubber wedge gate valves are less sensitive to debris in the controlled fluid, especially compared to other types of gate valves.
  • These valves are perfectly designed to meet different industry standards.
  • They are robust solutions for fluids containing a significant amount of impurities or debris.

Other Gate Valve Options

Different types of gate valves don’t finish with the few ones mentioned above. There are plenty more options for gate valves to be used for specific needs. A few examples of these various types are Parallel Slide Gate Valves, Expanding Gate Valves, Double Disc Gate Valves, and Triple Offset Butterfly Valves. Expert help can be fairly beneficial to choose the best option.   The table below compares the technical specifications of a few types of gate valves.  
Type Size Range Pressure Rating Temperature Range Application
Knife Gate Valve 2" - 72" Up to 250 psi -40°F to +400°F Wastewater, pulp & paper
Metal-to-Metal Sealing Gate Valve 2" - 48" Up to 4500 psi -20°F to +1200°F High temp & pressure
Rubber Wedge Gate Valve 2" - 72" Up to 200 psi -20°F to +250°F Drinking water, irrigation
Parallel Slide Gate Valve 2" - 36" Up to 4500 psi -20°F to +800°F High temp & pressure
Expanding Gate Valve 2" - 36" Up to 4500 psi -20°F to +1200°F Thermal expansion
Double Disc Gate Valve 2" - 24" Up to 1500 psi -20°F to +800°F Gas pipelines
Triple Offset Butterfly Valve 2" - 48" Up to 1440 psi -20°F to +800°F High pressure, tight shut-off
