    Category: Knife gate valve

    Description

    Premium knife gate valve combining durability and precision engineering. The valve body consists of WCB, CF8, CF8M, CF3M, and 310S materials while the disc options include SS304, SS316, SS316L, and 2520. The valve seats are available in STL, EPDM, PTFE, and VITON materials to ensure proper sealing. The valve sizes extend from 2”-24” (DN50-DN600) to accommodate different industrial needs. These valves operate within 0.6-1.6Mpa pressure range and Class 150lb rating to perform well in high-pressure applications. Knife gate valve manufacturers and suppliers choose these valves because they provide innovative solutions including pneumatic knife gate valves which address the distinctions between “knife valve vs gate valve” usage

    FAQ

    What is the operating principle of a knife gate valve?

    A knife gate operates by using a sharp-edged blade known as a “knife” to separate different media flows. The actuation of the knife valve controls the blade position which determines whether the flow continues or stops. The design of this valve maintains low pressure loss while protecting against clogging issues particularly when working with thick or viscous materials.

    What industries commonly use knife gate valves?

    – Mining and mineral processing
    – Wastewater treatment
    - Pulp and paper
    - Chemical and petrochemical processing
    – Food and beverage manufacturing

    What types of media are suitable for knife gate valves?

    – Abrasive slurries
    – High-viscosity fluids
    – Corrosive chemicals
    – Gaseous substances
    – Clean or dirty water

    How do knife gate valve differ from other gate valves?

    The Knife Valve operates effectively through dense media such as slurries and powders to maintain smooth operation in challenging conditions.
    The Knife Gate Valves operate effectively with clean or liquid flow and less abrasive materials yet they perform poorly with solids or highly viscous media.
