Fully adjustable pressure compensated flow control valve with reverse flow
check
SERIES 2 / CAPACITY: 45 L/min. / CAVITY: T-5A
Fully adjustable, pressure-compensated flow controls with reverse-flow check provide precise flow regulation for
meter-in or meter-out applications where there may be wide pressure fluctuations. They are infinitely adjustable
from nearly closed up to the maximum flow. An integral high-capacity check valve provides unrestricted flow from
port 2 to port 1.

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.
A balanced adjustment mechanism allows for easy adjustment even at high pressures.
The sharp-edged orifice design minimizes flow variations due to viscosity changes.
Minimum leakage is .2 gpm (0,8 L/min) when the adjustment mechanism is turned to the shut-off position.
Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
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.
