HPD16-S50

PILOTED DIRECTIONAL VALVE

Overview

Description

The HPD16-S50X is a high pressure, spool type, screw-in, cartridge style, pilot operated, hydraulic directional valve

Operation

In the neutral position flow is allowed between ports 3 and 2 bidirectionally while port 4 is blocked. On remote pilot signal at port 1 the valve's spool shifts to block port 2 while opening flow between ports 3 and 4 bidirectionally. The spring chamber is vented to the tank through port 5. The vented spring chamber allows the valve to be fully pressurized at ports 1, 2, 3 and 4 without affecting required pilot pressure. Pressure at port 5 will increase the required pilot pressure at a 1:1 ratio

Features

  • Hardened spool and cage for long life.
  • All HyPerformance™ products are tested to the rigorous standards of the NFPA specification T2.6.1 and are tested at a verification level of 90% and an assurance of 99%.
