HTD10-40 Valve

HTD10-40 Valve symbol

A high pressure, spool-type, screw-in, cartridge-style, hydraulic pressure reducing/relieving valve
that maintains the control port pressure at the midpoint of the supply port pressure.

The spool of the HTD10-40 is biased to block flow from port 2 to 3 and allow flow from port 3 to 4.
Pressure applied to port 2 shifts the spool to block flow to port 4 and allow flow from 2 to 3 until the
pressure at 3 is at the midpoint of the pressure at 2 and port 4. The valve relieves flow from 3 to 4
if the pressure at 3 increases above the midpoint. Port 1 is blocked (unused).

• Divides torque between two series motors.
• Accomodates differential flow (size optimized).
• Hardened spool and cage for long life.
• 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%.

   at 420 bar.
