Water Flow Control Needle Valve

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.

Water flow control needle valve.

They regulate the flow of a liquid or gas in metering applications. 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. 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. Plumbing needle valves restrict or allow flow by using a slender needle shaped plunger that fits in a conical seat.

The needle valve is bi directional while the flow control is one directional only. When you need to have a more precise resistance to flow in your non viscous system a needle valve just might be the solution. The 90 elbow shape allows you to install them in tight spaces. Control the flow of exhaust air while also regulating the exhaust air speed.

This controlled flow enters the input port and travels through the orifice which is actually sized by. Also known as quick exhaust valves.
