Description

A versatile valve used across a wide range of industries, the knife gate valve offers unique construction and functionality, making it suitable for situations where other valves would not suffice.

Notably, the knife gate valve features a blade-like design with a sharp metallic edge that efficiently cuts through materials it encounters, making it ideal for fluid or gas cutoff in diverse pipelines and industrial processes.

This valve finds common usage in industrial applications requiring precise pressure maintenance, like water and steam systems, sewage networks and plants and other fluid flow control scenarios.

Available in different sizes and materials, selecting the appropriate knife gate valve is crucial for its intended application.

Knife gate valves boast numerous advantages, including ease of use, reliability, and cost efficiency. Their stainless steel composition minimises corrosion damage, resulting in robust, reliable performance and not requiring frequent maintenance.

Laminar specialises in supplying knife gate valves for a wide variety of applications, including sludge and wastewater treatment plants, biogas substrate applications, and process technology. These valves deliver exceptional control over non-flammable viscous fluids with sludge or solids.

One noteworthy feature is that the knife gate valve seals are designed for flow in both directions, enhancing flexibility. With modular designs and actuator options, Laminar offers diverse products tailored to meet clients’ specific demands. Laminar offers three actuator options for knife gate valves; electrical, pneumatic (for quick opening and closing) as well as hydraulic actuators for marine and hazardous areas

FAQ's

The knife gate valve is an exceptional solution for fluid and gas flow control across various applications. Its distinct design, featuring a sharp edge that effectively cuts through viscous materials or seals, ensures precise regulation of pressure and efficient handling of fluids with sludge or solids.

With a modular design and electric actuator versions, this valve offers versatility to cater to diverse applications. A resilient seat guarantees full sealing, while its durable stainless steel stem and body enhance reliability. Other options are also available for the  body material like DI or carbon steel.

With its blade-like construction, the knife gate valve precisely manages fluid or gas flow in pipelines and industrial processes. The valve’s operation involves turning a hand wheel to move the gate up or down, enabling fluid passage or complete blocking as needed.

Knife gate valves are highly efficient and precise solutions for controlling the flow of liquids and gases.

Their unique design gives them an advantage over other valves, such as lower pressure drops across the valve. This makes them ideal for applications where reducing energy costs is important, such as drains and sewer mains..

Additionally, they can control larger flow rates than other valves can handle, so they are well-suited for high-pressure systems. Furthermore, their robust construction means that maintenance costs are low, while their long service life makes them cost-effective to own.

Finally, they are easy to install and maintain, making them a popular choice for many applications.

 

Knife gate valves are ideal for a range of applications, from controlling high-pressure systems to wastewater applications. They are highly reliable and robust, able to withstand extreme temperatures and pressures without needing to be replaced frequently.

Moreover, they can be used in hazardous areas as their construction makes them explosion-proof – an essential consideration for industrial settings.

Their ease of installation and maintenance makes them a popular choice among engineers, providing superior performance with minimal effort. As well as this, they offer significant cost savings due to their low energy consumption and long service life.

Their design is the main difference between a knife valve and a knife gate valve.

Knife valves have a blade that moves up and down within the valve’s body, while knife gate valves have a gate that moves laterally across the opening. It means that knife gate valves can provide more precise control, as there is less potential for leakage around the edges of the valve.

Additionally, knife gate valves are more reliable and durable than many other types of valves, making them an excellent choice for industrial applications.

Knife gate valves offer an impressive combination of performance and value, making them an ideal choice for a variety of industrial applications. Their robust construction ensures they can withstand extreme temperatures and pressures without compromising on quality or efficiency – delivering superior control and reliability to your system. Furthermore, their energy-saving design means you can enjoy substantial cost savings over the long term.

What’s more, knife gate valves are easy to install and maintain, so you can be confident that downtime is minimal. All of this makes them an excellent choice for a variety of industrial applications.
