Product description
The flow control valve type F is a fine throttle valve with an orifice-type throttling point. It basically consists of housing (1), adjustment element (2) and orifice (3) and is used for throttling of a flow with low temperature dependency.
The flow from A to B is throttled at the orifice window (4). The throttle cross-section is set by rotation of the curved bolt (5). Low temperature dependency is achieved thanks to the orifice design of the throttling point.
