Selection use

Use welded KLJZF when the piping is intended to be permanent and the buyer can confirm sanitary or industrial tube dimensions.

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, tubeOutsideDiameter, tubeStandard, 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 Welded KLJZF?
    Use welded KLJZF when the piping is intended to be permanent and the buyer can confirm sanitary or industrial tube dimensions.
  • 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.
