SP10-22A

PROPORTIONAL SOLENOID VALVE POPPET, 2 PORT, NORMALLY CLOSED

Overview

Description

A solenoid-operated, 2-way, normally closed, poppet-type, proportional, screw-in hydraulic cartridge valve, designed for low leakage blocking and load-holding applications.

Operation

When de-energized, the SP10-22A acts as a check valve, allowing flow from 1 to 2, while blocking flow from 2 to 1. When energized, the poppet lifts to open the 2 to 1 or 1 to 2 flow path.

Features

  • Linear metering
  • Continuous-duty rated coils
  • Protective screen option
  • Hardened steel work surfaces
  • Optional waterproof E-Coils rated up to IP69K
