Type Description Symbol Models Page
Needle Valves can vary the size of an orifice by adjusting 2N11 5Needle the position of the cone (needle) with relation to its seat. 2N400/401 6(Adjustable) Once open, the valve will continue flow in both directions. 2N600/601 8
Fully closed position will shut off the flow to the circuit. 2N800/801 9
Rotary spool valves vary the size of the orifice by openingRotary Spool milled slots to flow in a very linear relationship to the hand
2F400/401 7(Adjustable) knob position. These valves can be adjusted from full
open to full closed by rotating the hand knob 180°.
Restrictor valves throttle or block flow in one directionRestrictor through the use of a needle adjustment. A built-in reverse 2R11/2R14 10(Adjustable) free-flow check allows unrestricted flow in the reverse 2R400/401 11
direction.
Flow is throttled in one direction by a fixed orifice. TheRestrictor size of the orifice is predetermined for a specific applica-
2RN11/12/13/14/15/16 12(Fixed) tion and is not adjustable. A built-in reverse free-flow
check allows unrestricted flow in the reverse direction.
Types and Operation
Needles and restrictors are non-compensated flow controls whichprovide:Needle valves – Bi-directional and equal controlled flow for eitherdirection of main-flow.Rotary Spool – A fairly linear relationship between the number ofturns open and the controller flow.Restrictors – A controlled flow (fixed or adjustable) in one directionof flow and free reverse flow around the orifice in the oppositedirection.
GeneralNeedles, rotary spools and restrictors provide an adjustable or fixedflow orifice for precise control in circuits where pressure compensa-tion is not required. Typically the needle and restrictor valve orificedesign is sharp edged, so that flow at any setting is fairly insensitiveto temperature variations. These valves provide near zero leakageat shut off and fine control at low flow.

General ApplicationNeedle Valves are best suited to provide non-pressure compen-sated flow control in either direction for meter-in, meter-out or bleedoff circuits. These valves provide a virtually tight shut-off.Rotary Spool Valves provide the same flow control function asneedle valve and provide the added feature of linear flow vs rotaryadjustment relationship. The shut-off mode has minimal leakage.Restrictor Valves provide free-flow in one direction and restrictedflow, adjustable or fixed, in the opposite direction.

Features• Excellent adjustment pressure rotary

Use and operationThe manual rotary two way is a windowstyle metering valve. The rotary spool isturned and the intersecting milled slotsare opened to flow in a very linearrelationship to the handle position. Thevalve can be adjusted from full open tofull closed by rotating the hand knob180 degrees. In the full open position thevalve is rated for a maximum flow of 60 l/min at 7 bar ∆P. Because the valve isnot pressure compensated, flow throughthe valve can be affected by inletpressure. The spool style design doesnot lend itself to low leakage shut-offapplications.
Materials• Body — High strength steel with
black oxide coating.
• Cartridge — Steel construction with blackoxide coating and brass cap.
• Seals — Viton A standard.• Hand knob — Plastic standard. Metal
available.
