 Pressure vs. Temperature |
These 3-way ball valves in L or T configuration, operated by a single-acting (normally open or normally closed) or double-acting pneumatic actuator, offer multiple possibilities for controlling the direction of fluid flow within an installation.
These valves are suitable for use in aggressive environments. Their different operating modes are described in document D–913.20.
