HPC10-J48

DIRECTIONAL ELEMENT, PILOTED BALANCED POPPET NORMALLY CLOSED

Overview

Description

The HPC10-J48 is a high pressure, 2-way, bi-directional, pilot-to-open, balanced poppet-type, screw-in, cartridge style, hydraulic directional element designed to function as a load holding or blocking valve in applications requiring low internal leakage

Operation

In the unpiloted state, the valve blocks flow from ports 1 to 2 bi-directionally. On remote pilot signal at port 3, the valve shifts to allow flow from ports 1 to 2 bi-directionally. The spring chamber is vented to port 4. Pressure at port 4 will directly affect the pilot pressure required to shift the valve and must be added. The hydraulically balanced poppet will allow ports 1 and 2 to be fully pressurized without affecting required pilot pressure to actuate the valve. With port 4 vented the valve will fully shift with a minimum pilot pressure of 250 psi [17 bar]

Features

  • Bi-directional flow.
  • Balanced poppet.
  • Low internal leakage.
  • All HyPerformance products are tested to the rigorous standards of the NFPA specification T2.6.1.
  • All HyPerformance valves are tested at a verification level of 90% and an assurance of 99%.
