Two-Way Plug Valves
What are Two-Way Plug Valves?
Two-Way Plug Valves are quarter-turn valves designed for quick and reliable shut-off in dairy processing systems. These valves consist of a cylindrical or conical plug with a straight passage that allows flow in one direction and seals off completely when rotated 90 degrees. Their hygienic construction ensures smooth flow and zero contamination, making them ideal for milk, cream, yogurt, and similar fluid transfer.
Asiad Steel Industries is a leading manufacturer and supplier of high-performance Two-Way Plug Valves engineered for dairy-grade reliability and CIP/SIP compatibility.
Key Features
- Hygienic Design – Smooth surfaces with crevice-free internals to prevent bacterial buildup.
- Quick Shut-off – 90° rotation enables instant flow control or shut-off.
- Easy to Clean – Suitable for CIP (Clean-In-Place) and SIP (Sterilize-In-Place) processes.
- Robust Sealing – Prevents leakage and cross-contamination in dairy systems.
- Long Service Life – Made from SS 304/316L with food-grade sealing materials.
Types of Two-Way Plug Valves
- Manual Operated Plug Valves
- Pneumatic Actuated Plug Valves
- Welded or Tri-Clamp End Connections
- PTFE or EPDM Seated Plug Valves
