EC16-34 Valve
U.S. Patent 7,261,030

 

DESCRIPTION
A screw-in, cartridge-style, load sense, flow-on-demand pressure-compensator with built-in
damping and load-holding features for use in gravity-lowering circuits.

OPERATION
The EC16-34 is designed to be used in combination with a flow control valve for lowering and holding a load.
With inlet flow at port 2, port 3 will deliver required flow regardless of load pressure at 2. Port 1 of the
compensator must be connected to the outlet of a flow control valve that is connnected to the tank.

FEATURES
• Hardened parts for long life.
• Hardened seat for low-leakage load-holding capability.
• Quiet, modulated response.
• Industry-common cavity.
