After more than 1.5 million cycles of a high-cavitation stack mold running inkjet cartridge frames in a highly abrasive, 25%, carbon-fiber-filled PPO, and the inspections made during regularly ...

Company: Winters Instruments Product: NVA and BBV Series Needle Valves Description: Winters Multiport (NVA Series) and Block & Bleed (BBV Series) Needle Valves feature a one-piece, corrosion-resistant ...

The M3 threaded needle valve provides precise flow adjustments (0 to 1 SCFM at 50 psig) when space, leak-tightness, durability, and light weight are required. It can control minicylinders, nozzles ...

Ball and needle valves of the same size produce signi ficantly diƒfferent pressure drops. Ball valves generate little resistance to Š flow, whereas needle valves create sizable pressure drops.

The float operates the needle valve, letting fuel flow in when the level drops and closes when the correct level is reached. On the bottom for the carburetor you typically have two jets.

As the pressure in the evaporator decreases, the valve opens and allows more refrigerant to flow through it. As the pressure increases, the valve closes and allows less refrigerant to flow through it.

A SATISFACTORY adjustable needle valve for admitting a small constant flow of gas into a highly exhausted vessel is difficult to make. A number of ingenious forms have been described by various ...
