Tognella FT 1251/2 bidirectional flow restrictor, 1/2" BSP, for in-line mounting: it controls the flow in both directions.
Bidirectional flow control valve from the Tognella FT 1251/2 series, with 1/2" G threads, for in-line mounting. It throttles the oil in both directions, so the actuator moves more slowly both on extension and retraction.
It is set with the knob, and the same opening applies in both directions. If different speeds are needed each way, use a one-way valve on each line, such as the FT 1251/5.
The full code is FT 1251/2-12; the number after the dash gives the thread size.
