Service Instructions
The 944 Series Relief Valve has a tungsten carbide seat (9) and should not require frequent replacement. The tungsten carbide ball
(7), in normal service, will last a long time because it rotates and wears evenly. If there is leakage, replace the ball.
IMPORTANT: Open the adjustment knob (1) to full counterclockwise position before unthreading valve seat (9) from valve
body (4).
If the valve stem (3) is rotated inwardly with the ball removed, the PTFE O-ring (5) may require replacement. If there has been leakage
from the valve stem, the PTFE O-ring should be replaced.
IMPORTANT: The valve stem stop (6) must be unthreaded from the valve stem (3) with a socket screwdriver, then the valve
stem can be threaded out of the valve body.
IMPORTANT: All non-moving threads must be assembled with Loctite sealant, Titan part # 426-051.
