01 / OVERVIEW
A smaller footprint. The same attention to control.
A compact monoblock platform with one to seven independently operated spools. A 37 mm spool pitch and flexible port options keep your hydraulic layout focused.
Source note. The four-spool source drawing lists G 3/8–G 1/2 at T; the other six drawings list G 1/2. Confirm the return-port option for KM50-4.

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.
Pressure inletG 3/8 or G 1/2
Tank returnG 1/2
Work portsG 3/8 or G 1/2
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 REQUIREMENTS
Define the working envelope.
Match the KM50 configuration to your hydraulic system. Share the following application details with Komtes technical support to confirm the valve selection and its operating limits.
| Flow requirement | Specify pump delivery and the flow required by each controlled function, in l/min. |
|---|---|
| Working pressure | Provide normal working pressure, peak pressure and the required relief setting, in bar. |
| Return-line conditions | Specify maximum T-port back pressure, including the return filter and any downstream components. |
| Circuit arrangement | Confirm pump type, neutral condition, simultaneous functions and any carry-over connection. |
| Fluid & seals | Identify the hydraulic fluid and required seal compatibility. |
| Temperature & viscosity | Provide the fluid temperature range, ambient conditions and operating viscosity. |
Rated flow, pressure limits, relief settings and fluid compatibility must be confirmed for the selected KM50 assembly.
Confirm your configuration with Komtes05 / 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. Confirm the selected spool code with Komtes technical support. 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.
06 / SELECTION CHECKLIST
Bring the system into focus.
- 01
Define the controlled functions.
Select 1–7 spools or sections and describe each actuator’s required behaviour.
- 02
Confirm the hydraulic circuit.
Identify pump type, flow requirement, neutral condition and any carry-over requirement. Confirm the actual operating envelope. The valve selection guide includes a specification and enquiry checklist.
- 03
Check the interfaces.
Choose P, T and A/B port options. Review mounting points, overall dimensions and space for fittings and lever movement.
- 04
Release the configuration.
Agree the spool code, controls, relief setting, seal material and installation instructions before ordering.
