NCEC

Fully adjustable needle valve with reverse flow check

SERIES 2 / CAPACITY: 11 L/min. (3,3 mm) / CAVITY: T-5A

Needle valves with reverse-flow check are fully adjustable orifices used to regulate flow. They are infinitely

adjustable from fully closed up to the maximum orifice diameter. An integral high-capacity check valve provides

unrestricted flow from port 2 to port 1. They are not pressure-compensated.

TECHNICAL DATA

Maximum Operating Pressure 350 bar

Maximum Valve Leakage at 110 SUS (24 cSt) 0,3 cc/min.

Adjustment - Number of Counterclockwise Turns - Fully Closed to Fully Open 5

Locknut Hex Size 15 mm

Locknut Torque 9 - 10 Nm

Seal kit - Cartridge Buna: 990-203-007

Seal kit - Cartridge Viton: 990-203-006

TECHNICAL FEATURES

All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge

extension dimensions from the mounting surface may vary.

Because needle valves are non-compensating devices, the fixed orifice size will regulate flow through the valve in proportion to the square root of the pressure

differential across ports 1 and 2.

A balanced adjustment mechanism allows for easy adjustment even at high pressures.

The sharp-edged orifice design minimizes flow variations due to viscosity changes.

Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge

machining variations.

PERFORMANCE CURVES

For Series 1 cartridges configured with an O control (panel mount handknob), a .75 in. (19 mm) diameter hole is required in the panel.
