Specialityvalve is leading Knife Gate valve manufacturer in India. Knife gate valves are built to withstand harsh environments, with a sharpened blade that can cut through thick liquids.
It's made for turning on and off and isolating structures with a lot of dissolved stable particles. Knife gate valves are in handy when dealing with slurry, abrasive, corrosive, or viscous media. The valves feature a minimal strain drop when fully open, are easy to operate, lightweight, and cost-effective.
They're particularly effective in wastewater applications where corrosion is an issue. Apart from the optimized valve layout for slurry media, having an acid-proof stainless steel knife gate valve is advantageous since it is far less prone to corrosion and so requires far less frequent maintenance or replacement.

Following are some other valves we manufacture:

Non-Rising Stem Gate Valve
Specialityvalve is the largest Non-Rising Stem Gate Valve manufacturer in India. A Rotating Stem Gate Valve or Blind Stem Wedge Gate Valve is another name for a Non Rising Stem Gate Valve. When the gate is opened and closed, the stem of this sort of valve does not move up and down. Because the stem is not visible, we can't tell if the gate is open or closed by looking at the valve. These valves are similar to the Rising Stem Gate Valve in that they can be used in the same applications. They take up relatively little area in the system and are suitable for both high pressure and high temperature applications.

Rising stem Gate Valve
Specialityvalve is best Rising stem Gate valve manufacturer in India. Rising Stem is the type of gate Valve. The threads on rising stem gate valves are located on the outside of the valve body. When we open the valve stem of valve rises. Non-rising stem valves are typically made of brass, bronze, or cast iron, whereas Rising Stem valves are made of cast or forged steel. Rising stem gate valves are used in high pressure applications up to category 2500 or 420 bar. It allows us to see how far the valve is open. Because of the amount of visible stem, it is simple to determine whether a rising stem gate valve is open or closed. The valve is closed when the handle is flush with the pipe. The valve is open if there is a lot of stem exposed.

Super Duplex Gate Valve
Specialityvalve is best Super Duplex Steel Valve Manufacturer in India. Duplex Steel Valves are constructed from duplex grade steels. The microstructure of the duplex grade contains austenitic and ferritic phases, giving it high strength and corrosion resistance. Because of their metallurgy, these steels can be used in a variety of applications. This material is used to make valves that are dependable, strong, and corrosion resistant. Duplex stainless-steel valves are classified into three types: standard duplex, super duplex, and lean duplex. Each of them outperforms the former in terms of corrosion and strength. Valves of various types, such as ball valves and gate valves, are used for specific purposes in an application.
Specialityvalve is the best Super Duplex Gate Valve Manufacturer in India. These products are used in a variety of industries including chemical, petrochemical, energy, pulp, paper, and oil and gas processing. Various valves are available. Gate valves are usually manufactured in India.

Forged Steel Gate Valve
Specialityvalve is one of the top Forged Steel Gate Valve Manufacturer in India. Forged valves are made using a process called forging, which involves shaping metals and alloys while they are still solid. Heat and large industrial tools are used to bend metals and alloys, and dies are used to cut and shape the materials to form specialized valves.
Forged steel gate valves are strong, compact, and ideal for high-temperature applications. The Forged Steel Gate Valves can survive even the harshest conditions. When they’re open, the medium goes through the valve, making them suitable for enterprises that need to isolate viscous fluids and liquids. The valve includes an exterior screw and a yolk with a rising stem. The hand wheel is primarily used to operate the gate valve for both isolation and control functions. These valves offer positive tight shutdown in the horizontal or vertical position for process mediums in pipes. They can also be utilized to provide a little amount of control over steam, gas, or liquids. Because they are simple to use, these valves are utilized for isolating.
