Needle and Metering Valves. Needle Valves. Needle valves provide reliable and consistent flow control are offered in a variety of stem designs materials sizes and end connections and have been engineered to withstand corrosive and extreme conditions.
Hayward NVA Series Needle Valves Hayward NVA Series needle valves are used for accurate metering of fluids. Turning the thumbwheel moves a tapered piston into the PTFE seat to control the flow down to a few drops per minute.
Needle valves offer the most accurate flow control making them an excellent choice for precise metering of liquids or gases. Needle valves have a tapered needle like plunger that snuggly sits in the valve seat creating a leaktight seal that can withstand high pressures. Operators can fine tune or shut off flow by simply the threaded needle.

Jun 15 2020 Bubble tight needle valve offers precise trouble free pneumatic and hydraulic pressure control. Dual Piston technology features coarse and fine vernier volume adjusters enabling the operator to choose coarse control for large pressure changes or fingertip fine adjustment to effortlessly dial in pressure test points by as little as 0.001 psi.
With a pneumatically operated valve air pressure is used for actuation. The required control pressure is often in the range 0.4 to 0.8 MPa. A pneumatic cylinder transmits its movement to the valve plate. If a direction is operated by compressed air and the opposite direction reset with a spring the drive is called single acting pneumatic .
Feb 22 2013 Ron’s original design Starting with a steel valve stem took a piece of 6mm diameter mild steel and made a hole with a centering drill bit. both sides of the rod has to be supported to prevent the bar from bending this will keep the diameter constant and help to make vacuum tight seal with teflon washer. machining to 4.5mm in length of 40mm
SMC developed the LVN series chemical needle valve to overcome bubble generation when using light liquids. The LVN valve is manufactured from a lightweight PFA material which is highly compatible with acids bases and ultra pure water. Normally installed on top of a filter unit the LVN needle valve can regulate flow rates between 0 to 12 l/min

Of 316 stainless steel as standard and some as alloy 400 Hy Lok needle valves are meticulously designed for the flow temperature and system required. Common applications include pharmaceutical life support and oil gas. End connection options include male / female NPT Hy Lok tube fittings and ISO threads from 1/8″ to 1″.
A Needle Valve is a valve that has a small port and a threaded needle shaped plunger. It allows for fine flow adjustment however it is usually limited to low flow rates. Manual or motorized needle valves are available. The distance between the plunger and the valve seat is controlled by the handwheel in manually operated needle valves.
Needle valves are usually used in flow metering applications especially when a constant calibrated low flow rate must be maintained for some time such as the idle fuel flow in a carburettor.. Note that the float valve of a carburettor controlling the fuel level within the carburettor is not a needle valve although it is commonly described as one.
