Valve Application For Slurry And Paper Pulp

Slurry and Paper Pulp

TVCCL Gate valves and knife gate valves are advantageous in applications involving slurries, as their “gates” can cut right through the slurry. They are also used in applications that involve viscous liquids such as heavy oils, light grease, varnish and other non-flammable viscous liquids. TVCCL Gate valves and knife gate valves are available in large sizes to better handle thick flow. They are excellent for use anywhere a shutoff valve is needed.

KNIFE GATE VALVE FOR SLURRY AND PAPER PULP
For the difficult mud, TVCCL offers a perfect cutting edge design and it is extremely easy to customize and to maintain which lowers the total life cycle cost.
So Knife gate valves are so-called because of their ability to cut through media containing solids. They work by lifting a round or rectangular gate out of the path of the media. The sealing surfaces between the gate and seats are planar, so knife gate valves are often used when a straight-line flow of fluid and minimum restriction is needed.

TVCCL Knife gate valves were originally designed for the pulp and paper industry. Stringy pulp would get stuck between the wedge and the seat of a normal gate valve and prevent flow shut-off. Knife gate valves were specially designed with a sharp edge to cut through the pulp and seal.
TVCCL knife gate valve is designed and equipped to handle tough and abrasive shut off applications involving slurries, powders or granular substances as well as pulp stock, paper and recycled paper.

WHY USE A KNIFE GATE VALVE?
The main reason for choosing a knife gate valve is that they are cost-effective, easy to actuate and light. They are also extremely effective in many industries and processes. Knife gate valves were designed with a sharp edge to cut through the pulp and seal. With this type of useful attribute, the knife gate valve has become invaluable in applications involving slurry, viscous fluids and other systems where impingement is an issue.

ADVANTAGES OF KNIFE GATE VALVES
Knife gates are cheap, easy to actuate and light. They are advantageous in applications involving viscous fluids such as sludge and slurry because their blades can cut through thick liquids with ease. As such, they are generally specified in larger sizes for the handling of thicker flows in demanding applications.

GATE VALVE FOR SLURRY AND PAPER PULP
TVCCL Gate valves can be found anywhere an economical shut off is required. Gate valves are ideal for any application that involves slurries as the gate can cut right through. Gate valves are also common in applications using liquids like heavy oils, light grease, varnish and other non-flammable liquids. TVCCL Gate valves are primarily designed for on-off services. They are used in systems which require infrequent use of the valve too. The valves are designed for full-area flow to minimize the pressure drop and allow the passage of a pipe-cleaning pig.

KNIFE GATE VALVE AND GATE VALVE
One of the differences between the gate and the knife gate valves, is that the knife gate valve often has a sharpened disc to better cut through slurry/viscous media. Also, the knife gate valve has a short face-to-face length compared to a gate valve, which is dimensionally wider. As a consequence a knife gate valve is light weighted compared to the gate valve. These are the main differences and probably two of the biggest advantages of the knife gate valve.

TVCCL's Gate valves and knife valves are designed to minimize pressure drop across the valve in the fully opened position and stop the flow of fluid completely. The direction of fluid flow does not change, and the diameter through which the process fluid passes is essentially equal to that of the pipe. Hence, they tend to have minimal pressure drop when opened fully.

ADVANTAGES OF GATE VALVES
One of the primary advantages afforded by using gate valves is that the pressure which drops can be very low when gate valves are fully open.

    Gate valves offer an unobstructed media flow from any direction of the valve body. It does not decrease pressure which makes it suitable for pipeline where the flow direction may change. The overall structure length of gate valves is shorter than globe valves. The valve clack aligns with the valve body, thus making the structure length of gate valves shorter than globe valves. The seal functioning is quite good thus, making it less eroded while it is open. As compared to globe valves, the erosion of sealing surface is lighter. The valve body is simple and easy to operate. It features a good casting process which offers a wide range.

    Knife gate valves designed for use in the pulp and paper industry. Utilizing a sharp, beveled edge, a knife gate was ideally designed to cut through the stringy pulp encountered in the pulp and paper industries. The benefits of knife gates also include that they are easy to actuate and cheap to produce. can be applied wastewater treatment, oil and gas, mining, and power. Knife gate valves became advantageous in sludge and slurry applications because their blades can cut right through thick liquids easily.
