KLJZF Flanged Plastic-head Pneumatic Angle Seat Valve

KLJZF flanged pneumatic angle seat valve for flange-connected process piping, with plastic-head and stainless-actuator dimension references from the catalog. This card is specifically for the polyamide plastic-head actuator version.

Kailing KLJZF flanged plastic-head pneumatic angle seat valve
PUBLISHED PRODUCT

Use flanged KLJZF when the buyer's pipeline uses bolted flange connections and needs easier removal than welded piping.

Product Features Published highlights
  • 01
    Visible valve position

    The actuator provides an open and closed position indication for quick operating checks.

  • 02
    External pneumatic pilot

    External pneumatic pilot control is designed to extend service life and reduce maintenance.

  • 03
    Self-adjusting seal compression

    The overflow port and sliding-block structure automatically adjust seal compression to improve sealing performance.

Selection use

Use flanged KLJZF when the buyer's pipeline uses bolted flange connections and needs easier removal than welded piping.

Flow direction

For liquid service, the catalog recommends selecting low-in/high-out where water-hammer prevention is needed and keeping working pressure below 0.3MPa unless a double-acting actuator is selected. For steam or gas service, high-in/low-out can improve sealing, but service life should be reviewed.

RFQ confirmation points

Ask for medium, temperature, pressure, dnSize, flangeStandard, bodyMaterial, actuatorMaterial, airSupplyPressure, flowDirection, quantity. Include photos of the current valve or pipe connection when replacing an installed unit.

Frequently Asked Questions

  • FAQ When should buyers choose Flanged KLJZF?
    Use flanged KLJZF when the buyer's pipeline uses bolted flange connections and needs easier removal than welded piping.
  • FAQ What air supply does KLJZF require?
    The catalog lists neutral gas or air as the control gas and 0.4-0.8MPa as the air supply pressure.
  • FAQ Can Kailing quote by model name only?
    A model name helps, but the buyer should confirm medium, temperature, pressure, connection standard, body material, actuator material, flow direction and quantity before RFQ.
