Introduction :

  • The HPZ-Series Knife Edge Valve is a unidirectional wafer knife edge gate valve used on industrial pipeline for on-off operation. 

  • The structure of body and seat eliminates clogging shutoff for flow with fine particles. Additionally, beveled knife edge helps 

  • the gate cut through thick medium easily. According to different working situation: non-rising stem knife gate valve, wafer knife 

  • gate valve, lugged knife gate valve, pneumatic knife gate valve, electric knife gate  valve, manual knife gate valve and bevel 

  • gear knife gate valve are all available. 


Features :

  1. Body:

    a) Integral body with full bore structure ensures smooth flow, easy assembly and smaller shell leakage possibility.

    b) Guide claws design at the port bottom for gate fixture, instead of a groove, eliminates any potential clogging when valve shutoff.

  2. Gate:

    a) Beveled knife edge provides strong cutting stress and tight sealing.

    b) PTFE resilient point guider above the port prevents metal-metal contact between gate and body.

    c)  Gate thickness can be increased to meet higher pressure.

  3. Seat:

    a) Side-entry seat is replaceable, reducing the cost of maintenance.

    b) Preloaded seat is adjustable to meet different sealing class and compensate normal seat wear.

  4. Other:

    a) Double thrust bearing minimize the torque required for operation

Introduction :


The HCPZ-series through conduit knife gate valve is a bi-directional wafer knife gate valve. It is mainly designed for highly concentrated flow media. With a through going O-port plate, this valve provides a stable and safe shut-off performance without clogging. With double-seat design, it can handle flow in both directions. 


Features :

  1. Body:

    a) Full port design minimizes pressure drop and maximizes flow capacity. 

    b) Packing at both top and bottom eliminates leakage to surrounding.

  2. Gate:

    a) Though gate with o-port cut through a disc of media down when closing and return this portion back when opening. 

    This prevent media from clogging in the valve body cavity.

    b) Gate thickness can be increased to handle higher working pressure.

    c) Gate surface is well polished at both sides for tight seal and less jamming.

    d) Gate is hard chrome coated for better abrasion resistance. 

  3. Seat:

    a) Side-entry seat is replaceable, reducing the cost of maintenance.

    b) Seat retainer covers the side of seat and prevents seat from direct flow flushing.

    c) Preloaded seat is adjustable to meet different sealing class and compensate normal seat wear.

    d) With seats on both sides, valve can handle flow in both directions 100%.

  4. Other:

    a) Double thrust bearing minimize the torque required for operation
