HP05H valves provide high pressure

capability greater than D05H valves.

The valve’s low pressure drop is

enhanced with the use of the Dynex

standard subplate, which takes

advantage of the valve’s special

double tank port design.

Mounting

Although similar to standard NFPA

D05 (CETOP 5) valves in size, HP05H

valves require a special high pressure

mounting pattern. This pattern

incorporates auxiliary “X” and “Y”

ports for external pilot and drain.

Refer to page 3.

INTERNAL OPERATORS

The table shows available internal

operators and the most common spools.

Refer to Typical Model Code on page

9 to specify valve model. Contact the

Dynex Sales department for availability

of spool options not shown.

The function symbols in the table show

solenoid or lever actuated models as

reference. Air and hydraulic actuators

are also available.

Flow pattern in the center position

or during crossover is determined

by the selected spool. Refer to Spool

Descriptions below.

Flow Patterns

Actuator “A” opens flow path (P

→

A).

Actuator “B” opens flow path (P

→

Spring Centered and Spring Offset

models are spring positioned

unless actuated.

Detented Models (Solenoid Operated)

Code 3 operators (two position

detented) hold the spool in the last

actuated position. These valves can

be actuated momentarily (minimum

electrical signal duration, 50 ms) to

shift and hold the spool in that position.

Reverse “R” Option

(Internal Operator Code 4 Only)

Flow pattern can be altered with “R”

(Reverse Assembly) option. Refer to

Internal Operator Descriptions table

for flow pattern details.

VALVE MOUNTING

HP05H valves have a second “T” port into

a common tank passageway, for lower

pressure drop. HP05H valves require a

special high pressure mounting pattern

with auxiliary “X” and “Y” ports for

external pilot and drain.

Port O-rings are included with valves.

Mounting bolts must be ordered

separately: .3125-18 UNC-2B Threaded

x 1.00 inch (25,4 mm), Grade 8 or better,

four required. Recommended mounting

torque is 25 lb•ft (34 N•m).

X = External Pilot

Y = External Drain

In the case of a 68xx model, the X and Y

ports function as both External Pilot and

Drain.
