Compression x Compression is a brass globe valve fitting in the Shut Off Cocks series, with compression connections at both ends that control fluid flow through a built-in valve.

 

 

Pipeline pretreatment: Cut the pipeline to a flat surface, remove burrs, and ensure that the end face is vertical.

Compression end installation: sequentially insert the compression nut and compression collar, and insert the pipeline into the joint until the bottom.

Manually tighten the compression nut and then use a wrench to rotate it 1-1.5 turns (to avoid excessive force causing the collar to break).

Valve testing: Open the valve, check for leaks after introducing the medium, and verify the sealing by closing the valve.

 

 

Comparison items	Compression x Compression	Compression x Male Pipe	Ordinary globe valve
Connection method	Compression at both ends	One end compressed, one end externally threaded	Threaded or flanged connection
Installation convenience	Highest (no threading requirement)	Medium (requires handling of thread sealing)	Low (requiring welding or complex sealing)
Applicable scenarios	Temporary or frequent maintenance system for flexible/semi-rigid pipes	Connection between fixed equipment and pipelines	High pressure or permanent pipelines
Ccost	medium	medium	Higher (complex installation cost)

 

 

Select valve type based on function:

Ball valve: requires quick opening and closing (such as emergency shut-off).

Gate valve: precise flow control is required (such as cooling system regulation).

Choose sealing material based on the medium:

Water/Air: Standard EPDM sealing ring.

Oil/Chemicals: Choose FKM (fluororubber) or PTFE sealing rings.

According to the matching specifications of the pipe diameter:

Measure the outer diameter (OD) of the pipeline and compare it with the product specification sheet to avoid leakage caused by size discrepancies.

 

 

Advantages	limitations
Easy to install, no need for professional tools	Not suitable for ultra-high pressure (>16 bar) or high temperature (>150 ° C) scenarios
Reusable and detachable for use	The compression ring is designed for one-time use and needs to be replaced after multiple disassembly
Compatible with multiple flexible pipelines	Strict treatment of end face flatness is required for the installation of hard pipes
