Product definition and use

Flow-control valve mounted on the threaded end of spray/nozzle pipes to open/close and adjust coolant flow.
Can be locked directly to the spray pipe base or inlet to allow operators to quickly control coolant supply during operation or setup.
Balances cooling performance and coolant consumption in metalworking equipment for operational flexibility.

Application contexts

Situations requiring immediate on/off or flow adjustment of coolant.
Systems where multiple spray pipes share a coolant supply and individual branch control is needed.
When saving coolant or optimizing cooling efficiency is desired.
Processes with varying cutting conditions requiring rapid cooling adjustment.
When local fine-tuning is needed without changing the main system settings.

Design and materials

Material: copper, providing oil resistance, rust resistance and corrosion resistance.
Valve type: rotary design enabling full open, full close or fine flow adjustment.
Thread types: available in multiple male/female thread specifications to match spray pipes and bases.
Installation: can be directly fastened to the spray pipe threaded end or mounted on a base.

Main advantages

Allows immediate control of coolant on/off and flow rate for fast, intuitive operation.
Helps reduce coolant usage or increase cooling when required.
Copper construction ensures durability and corrosion resistance for long service life.
Standardized dimensions facilitate quick selection and replacement.

Selection and usage recommendations

Confirm the spray pipe and base thread specification to choose the correct thread type.
Assess whether frequent flow adjustment is required (if so, select an adjustable model).
Confirm coolant type (water-based or cutting fluid) to match material and sealing requirements.
Consider whether operators need local control at the machine for quick adjustments.

Applications

Conventional machine tools, CNC lathes, CNC milling machines, machining centers, CNC grinders and other metalworking equipment using spray pipes for cooling or chip removal.
