HPV12-21

NORMALLY OPEN PRESSURE COMPENSATED PROPORTIONAL FLOW REGULATOR VALVE U.S. PATENT NO. 8,253,063

Overview

Description

The HPV12-21 is a solenoid-operated, pressure compensated, spool type, normally open, proportional flow control regulator

Operation

With inlet flow at port 1 the HPV12-21 valve will regulate flow out of port 2 regardless of system working pressure with flow rate inversely proportional to current applied to the solenoid

Features

  • Continuous-duty rated coil.
  • Hardened spool and cage for long life.
  • Efficient wet-armature construction.
  • Cartridges are voltage interchangeable.
  • Waterproof E-Coils rated up to IP69K.
  • 960 hour salt-spray rated solenoid tubes.
  • All HyPerformance products are tested to NFPA specification T2.6.1.
  • and are tested at a verification level of 90% and an assurance of 99%.
