製品概要
The KOZO WCB High-Performance Double Offset Butterfly Valve is designed for compact industrial isolation where reduced disc/seat rubbing and quarter-turn operation are required. The double-offset geometry moves the disc away from the seat early in the opening stroke, reducing friction compared with a concentric butterfly valve.
主要な設計機能
- Double-offset disc geometry.
- ASTM A216 WCB cast-steel body.
- ウエハ, lug or flanged body options by configuration.
- クラス 150 / 300 / 600 family.
- ギヤ, pneumatic or electric actuation.

Double Offset vs Triple Offset
A high-performance double-offset valve commonly uses a resilient or polymer-based sealing system, while a triple-offset design typically uses metal-seated geometry for more severe temperature or pressure conditions. They should not be treated as interchangeable.
選定メモ
Seat type, 圧力クラス, fluid chemistry and temperature must be selected together. Actuator sizing should use the actual seating and dynamic torque for the chosen configuration.
