| | Write object_id directly to buffer, returns length written (excluding null) Useful for building compound strings without intermediate buffer.

Base class for all valve devices.
Valves currently have three properties:
- position - The current position of the valve from 0.0 (fully closed) to 1.0 (fully open). For valves with only binary OPEN/CLOSED position this will always be either 0.0 or 1.0
- current_operation - The operation the valve is currently performing, this can be one of IDLE, OPENING and CLOSING.
For users: All valve operations must be performed over the .make_call() interface. To command a valve, use .make_call() to create a call object, set all properties you wish to set, and activate the command with .perform(). For reading out the current values of the valve, use the public .position, etc. properties (these are read-only for users)
For integrations: Integrations must implement two methods: control() and get_traits(). Control will be called with the arguments supplied by the user and should be used to control all values of the valve. Also implement get_traits() to return what operations the valve supports.
