Overview

You need dependable control of hydraulic flow paths to start, stop, and reverse actuators safely.

Hydraulic directional valves route pressurized oil to cylinders and motors, define center behavior, and protect your equipment from unintended motion.

Hydrath offers cartridge and manifold solutions in 2/3/4/5‑way circuits, with ISO 4401/CETOP mounting and SAE/metric ports to integrate cleanly into mobile and industrial hydraulic power units.

Operating Principles

• Direct flow routing: opens or blocks specific passages to guide oil from P to A/B and return to T .
• Center conditions: set system behavior when neutral—unload pump ( P→T ), hold position (A/B closed), or fully closed.
• Check and shuttle logic: one‑way control and dual‑source selection ensure safe sequencing and reliable supply switching.
• Pilot and unloading functions: use pilot pressure to release checks or unload circuits for energy‑efficient standby.

Valve Families (Representative Models)

• Check valves (steel ball / cone): TCV‑06‑B , TCV‑08‑B , TCV‑08‑P , TCV‑10‑B , TCV‑10‑P , TCV‑12‑P
• You get low pressure drop forward flow with positive blocking in reverse; cone poppets support lower leakage at high pressure.
• Shuttle valves (double‑check): TSLV‑08 , TSLV6‑08
• You can select the higher of two pressure sources to feed a control line or safety circuit.
• Pilot‑operated check valves: TPCV‑10
• You lock a cylinder under load and release only with a pilot signal; ideal for holding functions on lifts and booms.
• Liquid‑controlled unloading valves: TPC6‑08 , TPC2‑10
• Hydraulic Solenoid Directional Valves
• Provide on/off and directional control in compact cartridge formats
• Span poppet and spool families with clear cavity mapping for 2/2, 3/2, and 4/2/4/3 functions.

You unload the main circuit under pilot command to reduce heat and energy consumption in standby.

Porting & Mounting

• Cavities: 06‑2 , 08‑2 , 10‑2 , 12‑2 for screw‑in cartridges; inline bodies available.
• Ports: SAE (e.g., 4T, 6T, 8T, 10T, 12T) and metric BSPP (e.g., G1/4, G3/8, G1/2, G3/4, G1) for broad compatibility.
• Manifold standards: ISO 4401/CETOP interface options for spool‑type directional control assemblies.
  Actuation Options
• 12/24V DC solenoid coils with IP‑rated protection for mobile and industrial environments.
• Pilot operation for low‑force shifting of main elements at high pressure.
• Hand lever actuation for simple, robust manual control.
• Proportional variants available where you need fine speed and position control.

Materials & Build

• Aluminum 6061‑T6 bodies for compact mobile layouts and weight‑sensitive applications.
• Steel and ductile iron bodies for high‑pressure, low‑leakage requirements and durability in harsh duty.
• Precision‑machined spools/poppets with deburring, cleaning, and dimensional control to maintain repeatable sealing.

Applications

• Mobile hydraulics: scissor lifts, tipping/dump trailers, electric straddle stackers—stable holding, safe lifting, smooth reversal.
• Vocational trucks and construction equipment: auxiliary functions, steering circuits, tool control with predictable neutral behavior.
• Industrial HPUs and automation: machine tools, presses, conveyors—energy‑efficient neutral, reliable sequencing, low downtime.

Selection Guidance

• Choose center condition first: P→T unload for energy savings, A/B closed for load holding, fully closed for safety isolation.
• Size by flow and pressure: match cavity/port to required L/min and verify pressure drop vs. flow curves.
• Specify actuation: solenoid (12/24V), pilot, or lever based on your control architecture and environment.
• Pick body material: aluminum for compact systems; steel/ductile iron for high pressure and minimal leakage.
• Define cracking and pilot ratios: set check opening and release characteristics to fit your actuator and safety needs.
