Use threaded KLJZF when you need G, ZG or NPT pipe-thread connection on a compact process line.
- 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.
- 04 High-flow Y-shaped body
The Y-shaped valve body combines a high-flow path with compact response.

Plastic-head product and ordering-code reference
This product page is for the polyamide plastic-head version. The existing displayed family ordering-code example includes SS, which the English catalog uses for a stainless-steel actuator head; it is not a confirmed plastic-head ordering code. Specify plastic head and request the exact configuration and current drawing before ordering. Do not transfer that SS example to a plastic-head purchase.
Selection use
Use threaded KLJZF when you need G, ZG or NPT pipe-thread connection on a compact process line.
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
For a quotation, provide medium, temperature, pressure, DN size, thread type, body material, actuator material, air supply pressure, flow direction, quantity. Include photos of the current valve or pipe connection when replacing an installed unit.
English threaded catalog reference
This English threaded catalog excerpt contains both plastic-actuator and stainless-actuator references. For this plastic-head product, use the plastic-actuator table and confirm the current model-specific drawing, thread and process duty before ordering.

Frequently Asked Questions
- FAQ When should buyers choose Threaded KLJZF?
Use threaded KLJZF when you need G, ZG or NPT pipe-thread connection on a compact process line. - 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.
