NOTE: DATA MAY VARY BY CONFIGURATION. SEE CONFIGURATION SECTION.

Fixed-orifice, 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. An integral high-capacity check

valve provides unrestricted flow from port 2 to port 1. The flow setting is specified by the user and is set at the

factory.

TECHNICAL FEATURES

Customer must specify a flow rating. Factory set flow ratings are within +/- 10% of the requested setting.

The tuneable control option provides +/- 20% variation from the nominal factory pre-set flow. Turn the adjustment clockwise to increase.

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.

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.
