NOTE: DATA MAY VARY BY CONFIGURATION. SEE CONFIGURATION SECTION.
The phaser check is a pair of checks, back-to-back, with the poppet at port 1 mechanically
actuated. The valve is meant to be installed into the piston of a cylinder. When the cylinder
reaches the end of its stroke the poppet in the phaser check is shoved off its seat allowing
flow through the piston. This allows two cylinders to get back into phase.

TECHNICAL FEATURESTECHNICAL FEATURES
This valve is not designed to handle side forces. Actuating direction must be axial, and contact surface must be perpendicular to
valve axis to within 5°.
This valve is NOT meant to be cam operated.
This valve is NOT to be used in place of a mechanical stop.
Maximum stroke of the poppet must be limited to .047 in. (1,2 mm) by a mechanical stop other than the valve itself.
Note: Port 2 of the T-162A cavity is not used with this valve.
Check valves offer extremely low leakage rates with a maximum leakage of less than 1 drop per minute (0,07 cc/min).
A cylinder that does its work while extending can put a large load on the rod gland at the end of its stroke. A phaser check in the
piston can limit the unnecessary force on the gland.
If you need to monitor the pressure in a cylinder, a phaser check can prevent the trapping of a false pressure value by a load
holding valve.
A phaser check in the piston of a vertically mounted cylinder will bleed air at the end of the stroke.
Phaser checks in the pistons of master/slave cylinders will synchronize the cylinders simply by taking the mechanism to the end of
its travel in both directions. This lends itself to dual cylinder steering applications.
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.
