Looking for precise, vibration-resistant, and tool-free connections for your instrumentation panels, lab setups, or hydraulic circuits? At Perfect Engineers, we manufacture and supply high-quality Compression Fitting Ball Valves designed to ensure leak-free, compact flow control in gas, air, steam, chemical, and liquid transfer lines.
Ideal for small-bore tubing systems, these valves provide quick installation with double ferrule compression ends, and are trusted in refineries, pharma, R&D labs, analytical skids, and high-purity systems.
A Compression Fitting Ball Valve is a quarter-turn shut-off valve with tube connection ends that use single or double ferrule compression fittings to create a strong, vibration-proof seal on metal or plastic tubing—no welding or threading required.
These are ideal for:
These valves are designed to fit between flanges without the need for bolt holes on the valve body—making them easier to install, remove, and maintain in tight pipeline layouts.
With tool-free clamp connections, our valves allow fast installation and removal, making them ideal for systems requiring frequent sterilization or cleaning in place (CIP/SIP).
