EC10-S31 Valve

SYMBOL:
EC10-S31 Valve symbol

DESCRIPTION
A screw-in, cartridge-style, pressure-compensator, intended for use upstream of a remote fixed or variable orifice to provide a constant flow rate regardless of load pressure changes.

OPERATION
The EC10-S31 delivers constant flow to port 1 regardless of load pressure changes.

FEATURES
• Hardened seat for long life and low leakage.
• Quiet, modulated response.
• Industry-common cavity.
