Specialityvalve is the well reputed Knife gate valve manufacturer in India.
Knife gate valves are mainly designed for on/off services having higher content of suspended solids. They are beneficial for handling slurry in addition to viscous, corrosive and abrasive media. They are easy to actuate and have relatively low weight and are also cost effective.
A type of machinery known as a knife gate valve utilises a blade to cut through obstructions in heavy liquids.
Knife gate valve over Gate valve- Knife Gate valve have sharp edges hence the cutting for slurries and viscous material is good compared to gate valve. They have short face-to-face length compared to gate valve. Knife gate valve is lighter in weight compared to gate valve.

Pneumatic knife gate valve manufacturer in India
Specialityvalve is well known Pneumatic knife gate valve manufacturer in India. Electric, pneumatic, and hydraulic actuators can all be used to open and close pneumatic knife gate valves. This valve is available in pneumatic and manual versions with unidirectional and bidirectional designs. Pneumatic knife gate valves are built to withstand demanding applications. They are extremely sturdy in design and have a single piece full port cast stainless steel body that is fully lugged. This can handle applications that are extremely demanding and guarantees no pressure loss and increased flow capacity. The pneumatic knife gate valve has a great surface quality on both sides and is constructed of stainless steel and other premium alloys to provide a reliable shutoff. Perfect stem seal and leak-proof gland packing are guaranteed by the machine the valve and well finished gland pockets.
Parts of Pneumatic Knife Gate Valve:
· BODY: The body of a pneumatic knife gate valve is a single, sturdy, heavy-duty casting that is flanged. The valve's design guarantees that its internal trim pieces come into contact with each other as little as possible, minimising wear and tear.
· KNIFE GATE: For tighter sealing and to prevent deformation under high pressure, pneumatic knife gate valves use thicker knife gates.
· STEM: The stainless steel gate of the pneumatic knife gate valve ensures easy, smooth, long-lasting operations, and dependable services.
· GLAND PACKING: A smooth fully machined packing, a cast gland follower, multiple packing, and correct levelling in a pneumatic knife gate valve produce uniform compression and minimal leakage from the gland part.
· SEAT OPTIONS: Both permanent and renewable types of seats are available for pneumatic knife gate valves. will enable us to provide a changeable seat for very harsh applications.
Types of Pneumatic knife gate valve:
· Bidirectional Pneumatic knife gate valve
· Unidirectional Pneumatic knife gate valve
Pneumatic knife gate valve is used in industries like:
· Water treatment industry
· Energy industry
· Power industry
· Chemical industry
Advantages of Pneumatic knife gate valve:
• It is made to switch between manual and pneumatic actuation quickly and easily.
• The horizontal bolting stabilises the gate and its clavis design ensures optimum alignment.
• For improved gland sealing, it has electrified quad seal packing.

Gate Valve Manufacturer in India
Specialityvalve is one of the biggest producer and supplier of Gate valve Manufacturer in India.
Gate Valve is a control valve that either allows the fluid flow or stops it depending upon our use. It is a most common valve for water valve systems. It is a linear motion valve that starts or stops the flow. It got its name from the element sliding into the flow stream to provide shutoff, hence acting like a gate. Thus it is used either in the fully closed or fully open positions.
Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid. When the gate is fully opened it enables the gate valve to offer straightway flow with very little pressure drop.
Gate Valves are also called as Sluice Gate Valve. Automated Gate Valve also exists which are either electric or pneumatic actuator, but as manual gate valve are cost effective hence it is affordable and as gate valves are used lesser.
Gate valves should not be used for regulation or throttling of flow because accurate control is not possible.
Components of Gate Valve
● Body
● Bonnet
● Body Seat
● Stem Nut
● Yoke Nut
● Stem
● Handwheel
● Gasket
Working of Gate Valve
The main three components of Gate Valve are: body, bonnet and stem
When the handwheel is rotated which rotates the stem and due to it there is vertical movement of the gate via threads. They are considered multi-turn valve as it requires more than 360 degree to fully open the gate. When the gate is lifted from the flow path, it is open and when it returns it is closed and hence the flow is stopped.
Types
1. Knife Gate Valve
2. Wedge Gate Valve
3. Parallel Slide Gate Valve
