**Key Features:** 1. **Long Service Life:** Reliable sealing with minimal maintenance. 2. **Low Pressure Loss:** Offers better flow characteristics than globe valves—about 75% of a gate valve of the same size. 3. **Multi-Functionality:** Suitable for on/off and throttling applications. Ideal for chemical environments due to flexible trim options. 4. **Lightweight & Compact:** A 10'' butterfly valve weighs only 1/9 of a 10'' gate valve and takes up 1/6 of the space, making installation easier and cost-effective. 5. **Bubble-Tight Sealing:** Resilient seat design ensures tight shut-off compared to metal-seated valves. 6. **Easy Operation:** 90-degree rotation for quick opening and closing. 7. **Cost-Efficient:** Approximately 35-40% less expensive than a gate valve of the same size. 8. **Self-Cleaning:** Reduces failure risks from debris in pipelines. 9. **Delivery Time:** 25 days after order confirmation. 10. **Standards:** Complies with EN, MSS, API, AWWA, and BS. 11. **Operation Type:** Level operation. 12. **Body Material:** Cast iron, stainless steel 304/316, aluminum bronze. 13. **Painting:** PTFE coating or nylon paint. 14. **Stem Material:** Carbon steel, SS416, SS410, SS304, SS431. 15. **Seat Material:** NBR, EPDM, PTFE. 16. **Pressure Rating:** PN10, PN16. 17. **Size Range:** 2'' - 24''. 18. **Packaging:** Export wooden cases or as per customer requirements. 19. **Payment Terms:** L/C, T/T, D/P.
**Notes:**
- The numerator of Φ3 represents 1.0MPa, while the denominator represents 1.6MPa.
- GB9119-98, ISO2084, BS4504 are used for 1.0MPa systems.
- H2 dimensions can be adjusted based on user requirements.
