Features:
Leflow’s Rubber sleeve slurry knife gate valve is designed for two split bodies with drop-tight seal for different slurry applications,which prevents slurry deposited around seat area and keeps the gate path and seat area clear.
The disc of Knife gate valve is flat, but the disc edge is knife-type oblique,Like the blade of knife, which can cut off the fluid easily,even if there are some solid particles. Because of its compact wafer structure, it is mainly for low pressure application. The ends can be Wafer, Lug and Flange types.
Knife Gate valve is commonly used in following application:
Pulp and Paper Industry, Mining,Power Plants,Food and Beverage, Chemical Plants and Water Treatment plants.
Each part of valve is designed specially and has following benefits:
Body The body design of knife gate valve has the advantages: simple,compact and reasonable structure,smooth port,small flow resistance, light weight, easy installation etc.
Disc Standard AlSI 304 or 316 stainless steel gate is grinded and polished smoothly as mirror,which can effectively avoid damage of packing and seat during open and close . The bottom of the gate edge is machined to a bevel,so that it cuts through the solids for a tighter seal in closed position.
Seat (resilient) The seat can be metal and soft.Metal is usually welded onto body, the common material is 13Cr and Stellite. The Soft seat is mainly NBR,EPDM,PTFE, Viton, Silicone etc. Unique design that mechanically locks the seal in the internal of valve body with a stainless steel retainer ring.Normally it is unidirectional seal design,and bidirectional seal as requested.
Packing Several layers of braided packing with a strong gland ensuring a tight seal. Available in a range of materials: Graphite, PTFE,PTFE+KEVLAR etc.
Stem Standard stainless steel stem with good corrosion resistance offers a long service life. For rising stem only, a stem protector can be provided for additional protection against dust while the valve in the open position.
Operation modes Lever, handwheel,chain wheel,Bevel Gear and Pneumatic or Electric Actuator.
Epoxy Coating AII cast iron and cast steel valve bodies and components are epoxy coated,well protecting inner port and surface against corrosive and dirty conditions for longer service life. The standard coating colour is RAL5010
Accessories and Options Deflection cone,V or pentagonal port,injection holes,Locking device, Solenoid valve, Positioner, Limit switches,Proximity switches,Magnetic switches,Air filter,Stem extension etc.
When dealing with abrasive and high-density slurries, a slurry knife gate valve is essential for reliable and effective flow control. Slurry gate valves are specifically designed to handle the toughest slurry applications, with slurry valve types tailored to meet different operational needs. Among these, slurry knife gate valves are highly valued for their ability to cut through thick fluids, ensuring minimal leakage and smooth operation. For those seeking quality and durability, slurry knife gate valve manufacturers offer a range of solutions, including custom designs from leading slurry gate valve factories. If you are looking for a trusted supplier, consider exploring China slurry knife gate valve options for high-performance and cost-effective solutions.
