Water Flow Control Needle Valve

Also known as quick exhaust valves.

Water flow control needle valve.

This controlled flow enters the input port and travels through the orifice which is actually sized by. When you need to have a more precise resistance to flow in your non viscous system a needle valve just might be the solution. Parker s family of needle valves feature a highly contamination tolerant design that allows for fine metering with manual adjustment to create and orifice and control flow. These valves can operate with hydraulic system flows as high as 225 lpm and pressures up to 420 bar with the option of an integrate reverse free flow check valve.

They regulate the flow of a liquid or gas in metering applications. These valves dump exhaust air to the atmosphere without routing it back through a directional control valve. In both the fittings there is a finely threaded stem which allows the gradual adjustment of the quantity of controlled flow which passes through the valve. Control the flow of exhaust air while also regulating the exhaust air speed.

The needle valve is bi directional while the flow control is one directional only. Brass and stainless steel needle valves for flow control on a reverse osmosis system system control or recycle valve.
