Smooth Control. Compact Design. Maximum Performance.
At Perfect Engineers, we manufacture reliable and precision-built Non-Rising Stem Needle Valves, ideal for space-constrained installations and systems requiring compact shut-off solutions. With a rotating stem inside the bonnet, these valves do not extend upward during operation, making them perfect for tight panel layouts, enclosed systems, and automated process lines.
Backed by precision machining and leak-free testing, our valves are trusted in water treatment, pneumatic systems, lab gas distribution, and OEM skids.
A non-rising stem needle valve has a threaded stem that rotates in place to move the needle up or down without altering the stem’s external height. This design makes it ideal for confined areas where vertical clearance is limited or visual position indication is not required.
Preferred in instrument panels, pneumatic control boxes, and general fluid shut-off systems where space-saving is a priority.

Yes. With the right seal (PTFE/PEEK), they can handle compressed air, N₂, CO₂, hydrogen, and other gases up to 6000 PSI.
Standard sizes range from ¼” to 1”, with BSP/NPT/compression ends available.
Yes. These valves can be supplied with panel mounting hardware and locking nuts.
Needle valves offer precise throttling, while globe valves are more suited for on/off or less precise control.
