About this product
1. Wafer style butterfly valve
2. Technology demands of manufacture and acceptance: API 609 & API 598
3. The flange dimension connection pipe: ANSI 150
4. Body material: Ductile iron
5. Seat material: EPDM
6. Working temperature: -4 ~ +248℉
7. Nominal pressure: 225 Psi
1. The product is a neutral line without pin structure, which effectively reduces the probability of internal leakage of the valve.
2. The friction coefficient is small, and the operating torque is reduced by 30%-40% compared with the ordinary pinned butterfly valve.
3. Alkali resistant, salt and weak acid corrosion, inert to organic matter, wide range of applications.
Demands of Technology:
(1) Technology Demands of manufacture and acceptance acc. to API 609 and API 598
(2) The flange dimension connection pipe to be conformed to ANSI 150.
