The Marwin 3L/T‑2100F‑F Series is a robust 3‑way multi-port ball valve designed for reliable shut-off and directional flow control in industrial process systems.
Side entry design
Featuring a side-entry, bolted body construction, the valve offers strength and ease of maintenance while maintaining tight shut-off performance. The design incorporates four seats and precision ball alignment, supporting consistent sealing across multiple flow paths.
Port configurations
Available with both L‑port (diverting) and T‑port (mixing/diverting) configurations, the valve enables flexible control of process flow using a single unit—often replacing multiple 2‑way valves and simplifying piping layouts.
The inclusion of an ISO 5211 mounting pad allows straightforward integration with pneumatic or electric actuators, making the range suitable for both manual and automated applications.
Valve design
Three‑way valves such as this are specifically designed to divert, mix, or isolate flow, offering a compact and efficient solution for systems with multiple flow paths.
Applications
Common process applications and industrial uses include:
- Flow diversion between two process lines
- Mixing or blending applications
- Switching between pumps, tanks, or safety systems
- Utility and process line routing
- OEM machinery and skid systems
Other features
- Bolted, cast body construction for strength and durability
- Blow-out proof stem design for safety
- 4-seat design for improved sealing performance
- Live-loaded PTFE packing for long-term sealing
- Secondary stem seal (O‑ring) on smaller sizes
- Trunnion-mounted ball (2‑1/2"–6") for stability at higher loads
- Locking device provision for safety and process control
- Optional 180° rotation configurations available
