EC10-40

PRESSURE COMPENSATOR

Overview

Description

The EC10-40 is a screw-in cartridge style, pressure compensating element, intended for use with a remote fixed or variable orifice to yield a three port (bypass type), pressure compensated, flow regulating hydraulic valve

Operation

The EC10-40 maintains a constant flow rate from port 3 regardless of load pressure changes in the circuit downstream of port 3. The EC10-40 is a priority type valve, delivering pump flow first to port 3 then bypassing excess to port 2. All ports may be fully pressurized

Features

  • Hardened parts for long life.
  • Quiet, modulated response.
  • Industry-common cavity.
