2TCL10 – Throttle / Check Valve (Modular)
The Polyhydron 2TCL10 is a modular, sandwich-style hydraulic valve used to control the speed of an actuator (like a cylinder or motor). It works by throttling (restricting) the oil flow in one direction while allowing free flow in the opposite direction through an internal check valve. Because it is a modular “stack” valve, it mounts directly under a directional control valve, saving space and eliminating extra piping.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
About this item
The Throttle/Check Valve (Modular) – 2TCL10 (New Product) is designed to control flow in one direction through simple throttling. It features a double throttle cum check design, allowing free reverse flow that remains unaffected by the throttle setting in the opposite direction. Its modular construction ensures easy installation and efficient performance in hydraulic circuits.
| Model | Throttling Port | Approx. Mass |
|---|---|---|
| 2TCL10A | Port A only | ~2.0 Kg |
| 2TCL10B | Port B only | ~2.0 Kg |
| 2TCL10AB | Both Ports A & B | ~2.1 Kg |
Key Specification & Features
- Function:Â Controls hydraulic fluid flow in one direction via simple throttling while allowing free, unrestricted flow in the reverse direction.
- Modular Design: These valves are built for compact, stackable “sandwich” mounting, conforming to international interface standards like ISO 4401.
- Operating Pressure: Max working pressure of 315 bar.
- Configuration:
- Available for throttling on A port, B port, or both (AB ports).
- Can be converted between Meter-in and Meter-out conditions simply by rotating the valve body 180° along its longitudinal axis during installation.
- Adjustment:Â Features a throttling screw (clockwise rotation increases pressure drop/restricts flow) with a check nut for locking and a protective cap.
- Flow & Viscosity: Suitable for a viscosity range of 10 cSt to 380 cSt and temperature range of -10°C to +80°C.
