High temperature knife gate valve
High temperature knife gate valve
High temperature knife gate valve Product introduction
High temperature knife gate valve with a temperature resistance of 1000°C is suitable for the control of high temperature materials. In the ash and slag conveying system such as circulating fluidized bed boilers, boiling furnaces, and pulverized coal furnaces, high temperature knife gate valve can adjust the conveying volume of ash and slag, stabilize working conditions, and facilitate environmental protection.
High temperature knife gate valve is widely used in power station boiler ash and slag conveying system. The high temperature knife gate valve is the control of high-temperature resistant materials on the market in metallurgy, coal, chemical pharmaceutical and other industries. The materials such as 310S and 2520 have the characteristics of high-temperature resistance. They can be protected by extending the valve stem and adding heat sinks. It effectively solves the shortcomings of working under high-temperature conditions that other knife gate valves do not have. High temperature knife gate valve is suitable for ironmaking, power station, high-temperature coal furnace and other industries. Compared with other valves, it has simple structure, convenient operation and easy maintenance.
The high temperature knife gate valve is one piece body, metal seated structure, wafer or lugged end, which is suitable for use in more fibrous fluids, such as paper industry and wastewater lines. High temperature knife gate valve can also be produced according to its fluid properties. High temperature knife gate valve can be flywheel, gear box, chain wheel, pneumatic actuator and electric actuator. There is rising and non-rising alternatives.
High temperature knife gate valve adopts wafer type or lug type connection.The wedge type limit stopper can provide sealing the guide nail can provide good guiding function;The anti-adraslve bushings of different materials can be provide according to requirements so as to prolong the service life .Actuators(electric,gear box,pneumatic,hydraulic)can be freely selected.
High temperature knife gate valve specification:

High temperature knife gate valve feature:
• One piece cast body with guides to support gate and seat wedges.
• Provides high flow rates with low pressure drop.
• Various seat and packing materials available.
• Face to face dimension in accordance with manufacturer's standard.
• An arrow is marked on the body indicating the flow direction.
High temperature knife gate valve advantage:
- Full open valve provides a very low and smooth transition for flow.
- Flow can be in both direction.
- The valve can be installed in any position. However, it is preferable that the stem is perpendicular to the ground and the flywheel on top.
- Shorter valve length, even at large nominal diameters.
- Economically and conveniently available.
- There are types suitable for high pressures. - Easy to maintain.
High temperature knife gate valve application:
This knife gate valve is suitable for liquids that contain a maximum of 5% suspended solids. If it is used for dry solids in gravity feed applications it should be installed with the arrow on the body pointing in the opposite direction to the flow.
Designed for applications such as:
• Paper Industry
• Mining
• Silo emptying
• Chemical plants
• Pumping
• Food Industry
• Sewage treatment
