KM80

Monoblock directional valve · 1–7 spools

01 / OVERVIEW

Purposeful engineering. Every connection considered.

A monoblock directional valve with a 45 mm spool pitch, larger connection options and one to seven spools. Explore the assembly, then take the exact drawing into your design.

03 / PORT CONNECTIONS

Connect with confidence.

Use the port designation and threading callouts from the selected configuration. Alternative sizes indicate connection options; they are not interchangeable fittings.

P

Pressure inletG 1/2 or G 3/4

T

Tank returnG 3/4

A/B

Work portsG 1/2 or G 3/4

A1 / B1FUNCTION 1A2 / B2FUNCTION 2A3 / B3FUNCTION 3

Each numbered A/B pair belongs to one spool. “Three spools” describes three controlled functions, not three total fluid connections. Follow the actual port labels on the selected assembly.

The source uses G-thread designations. Verify the selected thread, sealing arrangement and mating fitting against the physical valve and approved connection specification.

04 / OPERATING REFERENCE

Define the working envelope.

The following provisional profile uses Walvoil SD11 catalogue data as a technical reference, as requested. These values have not been verified by Komtes testing and must not be treated as a released Komtes pressure rating.

Unverified comparison-based operating profile
Nominal flow · reference70 l/min
Maximum inlet pressure · reference315 bar
T back pressure · reference25 bar
Fluid temperature · reference−20 to +80 °C · NBR
Operating viscosity · reference15–75 mm²/s
Reference fluidMineral-based hydraulic oil
Catalogue measurement condition46 mm²/s at 40 °C

Maximum pressure for the parallel reference circuit. Series circuit: 250 bar. The reference family has the same 45 mm spool pitch; its six-spool limit is not applied to the seven documented Komtes configurations. Similarity of construction does not establish identical performance or replacement compatibility. Confirm pressure, return-line limit, relief setting, seals and fluid conditions for the actual Komtes configuration.

05 / CONTROL & SPOOL OPTIONS

The right control behaviour.

Manual control

Manual lever assemblies, control covers and rubber dust boots are shown in the product drawings and photographs. The public model illustrates the assembled exterior.

Pneumatic components

The supplied KM50 and KM80 libraries include pneumatic control components. Confirm the available kit, pilot supply requirements and positioner with the selected valve.

Spool reference codes

The source CAD library includes STD, AK, AT, BK, BT and ABT spool labels, using historical KM45L or KM70L part names. Treat these as source identifiers. A code alone is not a verified hydraulic circuit diagram.

Specify the required neutral condition, single- or double-acting function, detent or spring return, and relief requirements using an approved hydraulic schematic. No competitor ordering code is presented as a Komtes part number.

06 / SELECTION CHECKLIST

Bring the system into focus.

  1. 01

    Define the controlled functions.

    Select 1–7 spools or sections and describe each actuator’s required behaviour.

  2. 02

    Confirm the hydraulic circuit.

    Identify pump type, flow requirement, neutral condition and any carry-over requirement. Confirm the actual operating envelope.

  3. 03

    Check the interfaces.

    Choose P, T and A/B port options. Review mounting points, overall dimensions and space for fittings and lever movement.

  4. 04

    Release the configuration.

    Agree the spool code, controls, relief setting, seal material and installation instructions before ordering.
