PE42-S67H

PROPORTIONAL PILOT OPERATED SPRING CENTERED SPOOL DIRECTIONAL VALVE U.S. PATENT NO. 6,554,014

Overview

Description

The PE42-S67H is a screw-in, cartridge style, proportional, spring centered spool, pilot operated hydraulic directional valve

Operation

In neutral position inlet port 3 is blocked and ports 2, 4 and 5 are communicating with each other. On remote pilot signal at port 1 the valve's spool shifts proportionally to the applied pilot pressure to allow flow from port 3 to port 4, thru a load, such as hydraulic cylinder or motor, and then from port 2 to port 5 and to tank. On remote pilot signal at port 6 the valve's spool shifts proportionally to the applied pressure in opposite direction thus reversing the flow direction. The valve's spool is symmetrical providing only meter-in control

Features

  • Hardened spool and cage for long life.
  • Cost-effective ISO cavity.
  • Excellent metering characteristics.
  • Good Linearity.
Pressure Ratings
Pressure rating:
  • 345 bar (5000 psi) For port 3
  • 241 bar (3500 psi) For ports 2 and 4
  • 27.6 bar (400 psi) For ports 1 and 6
Note:
  • Polyurethane seals are recommended for 345 bar (5000 psi) inlet pressure operation. Available aluminum bodies for this product are rated 241 bar (3500 psi)
Flow Ratings
Maximum internal leakage:
  • 1180 ml/min (72 in³/min) At 207 bar (3000 psi)
Note:
  • Orifice diameter between ports 2 and 4 and port 5 in neutral position 76 mm (0.030 in)
Displacement per stroke:
  • 2.46 cm³ (0.15 in³) per stroke direction
Materials:
  • Steel with work surfaces hardened, external surfaces are zinc plated buna N o-rings are standard
Unit weight:
  • 0.76 kg (1.68 lb)
