Fully adjustable needle valve with reverse flow check
SERIES 1 / CAPACITY: 4 L/min. (1,5 mm) / CAVITY: T-13A
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: 990-010-007
Seal kit - Cartridge Polyurethane: 990-010-002
Seal kit - Cartridge Viton: 990-010-006

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