Automator Diaphragm Actuator – SRD4
Documentation
Specifications
Overview
The operating pressure, output torque and drive type are determined by the actuator designation.
Maximum operating pressure is 100 psi (7.0 BAR). (See Table 2.0)
Actuator designation example:SRD4C-MJ-FS-MN is a SRD4 spring diaphragm actuator that has a 50 –
70 psi (3.4 – 4.8 Bar) spring, an end of spring stroke output torque of 2752 IN•LBS (311 N•m) and uses
a 27×27 mm female double square and F05 + JB51 + F07 mount configuration to connect and drive
the valve. This actuator is with Namur stem.
