Product Name: ASTM A351 CF8 Knife Gate Valves
Type: Unidirectional Knife Gate Valve
Body Material: ASTM A351 CF8
Size: 6 Inch, DN150
Pressure: Class 150 LB, PN16
End Connection: Lug
Operation: Pneumatic Actuator with Limit Switches

The KU Series Knife Gate Valve is a unidirectional wafer valve designed for on-off operation in industrial pipelines. Its innovative structure effectively prevents clogging during shutoff, even when handling media containing particles. The beveled knife gate design generates significant shear stress, enabling easy penetration through the flow, making it ideal for demanding applications where efficient flow control is essential.

Product Features

» Cast-in Guide Claws – The guide claws at the port bottom secure the gate, replacing grooves and preventing clogging during shutoff, ensuring a tight seal by pushing the gate towards the seat in the closed position.
» Integral Body Design – This design ensures easy assembly and prevents shell leakage, improving the overall reliability of the valve.
» Full Port Design – The full port construction minimizes pressure drop and maximizes flow capacity for efficient fluid control.
» PTFE Resilient Points – These points prevent metal-to-metal contact between the gate and body, enhancing durability and reducing wear.
» Compact Construction – The super-thin body design and compact construction make for easy installation in confined spaces.
» Beveled Knife Edge – Provides strong cutting stress for efficient flow penetration and ensures tight sealing during operation.
» Adjustable Gate Thickness – The gate thickness can be increased to handle higher pressure requirements.
» Replaceable Side-entry Seat – Reduces maintenance costs by allowing easy seat replacement.
» L-Shape Seat Retainer – The retainer locks the seat into the valve body and shields the seat side to prevent direct flow flushing, improving valve longevity.
» Stem Cover – A stem cover is available to extend the service life of the stem by providing extra protection.
» Low Torque Operation – Two thrust bearings reduce the torque required for valve operation, enhancing ease of use.
» Grease Nipple – Equipped with a grease nipple to simplify bearing lubrication and reduce maintenance efforts.
