c) Bracket & Joint connection.
Wherever for technical reason the plant installation requires a distance between actuator and valve, or the valve flange and/or stem
are not standard, and in any case, where the valve/actuator connection could not be possible, a bracket and joint is the right answer.
The Bracket is a steel bridge that allows to connect the valve with is own flange connection in one side and with the suitable actuator
connection onto the opposite side, living a space in between for a steel joint connection. The joint allows a drive connection between
the actuator and the valve stem indispensable in case of stem key drive and flat head.
Chose the suitable flange bracket and the required joint connections to fix the actuator onto the valve very tight without any plays.

6. MATERIALS AND THEIR DURABILITY
Life time 20 years or number of cycles as per EN15714-3 2009 (see table below).
Nominal torque (a)* Nm
≤125
≤1 000
≤2 000
≤8 000
≤32 000
≤63 000
≤125 000
≤250 000
(a)* Based on EN ISO 5211.
(b)* One cycle consists of nominal 90° angular travel in both directions (i.e. 90° to open + 90° to close). For angular travel other than
90°, the endurance shall be agreed between the purchaser and the manufacturer/supplier.
(c)* For thermoplastic actuators the minimum number of cycles shall be 250 000.
Should it be necessary to replace its pistons sealing, these operations must be done by ACTUATECH trained people with proper
tools, we recommend to return the actuator to ACTUATECH where the actuator will be overhauled and than tested for a correct re-
placement.
On request ACTUATECH will be willing to provide its sealing Kits.
WARNING: ACTUATECH declines any responsibility for the products repaired by third parties.
