DESCRIPTION
A screw-in, cartridge-style, variable orifice, hydraulic flow restrictor valve that requires only
5-1/2 turns for full adjustment.

adjustment rotation. Effective adjustment is linear over the 5-1/2 turn adjustment range.
Settings are lockable in any position.

FEATURES
• Adjustments cannot be backed out of the valve.
• Desired settings may be locked down.
• Hardened parts for long life.
• Positive shut-off.
• Linear adjustment.
• Industry-common cavity.
