3L & 4L Series Hand-Pull Valve
Product Features
- Direct Acting Mechanism: Both 3L and 4L series operate using a direct-acting, hand-pull mechanism, ensuring rapid response and immediate flow direction change.
- Robust Construction: The valve body is constructed from durable aluminum alloy, providing excellent resistance to wear and ensuring a long service life in industrial environments.
- Smooth Operation: The internal spool is precision-machined, reducing friction during manual actuation and providing a smooth, reliable switching feel.
-
Port Configurations:
- 3L Series: 3-Port 2-Position design, ideal for controlling single-acting cylinders or basic directional control.
- 4L Series: 5-Port 2-Position design, perfect for controlling standard double-acting cylinders.
- No Lubrication Required: Designed to operate efficiently without added lubrication. (If lubrication is used, it must be maintained continuously with ISO VG32 oil).
- Flexible Thread Options: Available with PT, G, and NPT thread standards to match various global piping requirements.
