Features
- CNC precision‑turned components：Body and disc are fully CNC‑machined to guarantee precise sealing mating surfaces.
- Threaded hygienic connection：Tool‑friendly threaded ends allow quick installation and removal, no on‑site welding needed for easy maintenance.
- Hygienic dead‑leg‑free flow path：High‑precision inner polish, suitable for CIP cleaning, prevents medium residue.
- Versatile sealing solutions：EPDM as standard; PTFE / FKM / Silicon optional, reliable performance under full vacuum and varied temperature conditions.
- 100% pressure‑tested before shipment：Every valve passes shell pressure test and seat leakage test to ensure zero‑leak performance.
- Dual‑mode actuation：Manual handle or pneumatic actuator for 90° rotation, for shut‑off and throttling service.
- Global sanitary standard compliance：Conforms to 3A, SMS, DIN, ASME BPE; fits food, pharmaceutical and liquid‑cooled data‑center fluid systems.
Working Principle
The sanitary threaded butterfly valve applies the identical disc-rotation working principle, with the ends machined to sanitary threads (SMS, DIN or ISO) so the valve screws directly onto threaded pipe ends or equipment ports. This eliminates on-site welding and pipe cutting, enabling fast installation and simple replacement in retrofit or modular systems. The thread joint is sealed with a food-grade gasket or thread sealant, and the connection can be released easily whenever the valve needs to be swapped or serviced
