Features
The most important function of the PTFE butter y valve is its stem seal.
The pressure to keep the two sealing surfaces together is provided by an upper and lower set of spring resulting in a superior stem seal.
One-piece disc-stem design provides a high Cv (Kv) value.
Mounting Flanges according to ISO 5211 allow a close mounting of Gear, Actuator.
