A new needle-drive unit for hot-runner valve gates is said to overcome several limitations common to single-shot needle valves
New techniques employ self-calibrating needle valves
to eliminate significant back pressure on the gas supply unit, thus avoiding conditions of choked gas flow.
Kandl said that, in addition to a needle valve
, the redesigned regulators are available with a packless diaphragm.
The current operating status of each needle valve
nozzle is indicated on the screen by a bar display (green = open; red = closed).
Limited Tenders are invited for 1)Ss 10 Nb (3/8") Needle Valve

The regulator also features a built-in lubricated needle valve
that provides easy control of flow volume.
Limited Tenders are invited for Ss-316, Needle Valve
& Brass Needle Valve
It includes the "LI" lightweight internal-mix gun, which has a needle valve
to permit adjusting catalyst and resin pressures to matching levels.
The xQR41 Series MicroDot needle valve
, introduced in June, features a 60% smaller form factor, an exchangeable modular design for greater customization and process control, and a Quick Release (QR) clasp that allows easy removal of the fluid body to replace wetted parts in seconds.
