The actuators are sealed for life and are not serviceable. The actuator is provided as spring to close/air to open (normally closed).
  • Page 7 Stainless Steel Pneumatic Actuator 51 (2”) & 76 (3”) The stainless steel pneumatic actuator for valves 51 (2”) and 76 (3”) is sealed and not serviceable. The actuator is bolted to the housing. The pneumatic actuator is provided already pre-assembled with the adapter and adapter plate (see figure 6).

  • Page 8: Diaphragms

    1.3.3 Diaphragms The valve has three different diaphragm material options. Consult Steridose for availability of each material for any particular valve size. Diaphragm material selection is a function of chemical compatibility with the process fluid (s), including CIP solutions/steam, operational temperature and number of cycles.

  • Page 9: Assembly

    Assembly General When installing the valve sufficient clearance to remove/assemble the actuator must be considered. The amount of space required depends on valve size and actuator configuration. In order to ensure self draining, the valve must be installed in the correct position. See figures 10 and 11: Figure 10: Self draining positions for process valves The housing is self draining in these positions,...

    2.1.1 Valve housing to actuator connection The valve housing and actuator are connected with either a hygienic clamp union or bolts, as indicated below: Size 12 (1/2”): TC CLAMP 1"/ 1.5" Size 25 (1”): TC CLAMP 2.5" Size 38 (1 ½”): TC CLAMP 2.5"...
  • Page 11 Figure 13: Replacement of pressure plate type 1 for type 2 For valves 12 (1/2”) to 76 (3”), with PTFE diaphragm, no pressure plate is required in the valve stem. The PTFE diaphragm is provided with a threaded stud that will screw direct to the valve stem.

  • Page 12: Assembly Procedure

    Assembly Procedure 2.2.1 Pneumatically operated valves In order to install the pneumatic actuator to the valve, follow these steps: 1-Attach diaphragm to actuator stem, or screw the valve diaphragm to the actuator stem. Refer to section 2.1. 2-Actuate the actuator to the open position. If the actuator is set-up as normally closed, actuate the actuator to the open position.

  • Page 17: Operation

    OPERATION 3.1 Pneumatically operated Valve The pneumatically operated actuator type S-A is opened when pressurized and closed otherwise. The pneumatically operated actuator type A-A is opened when the lower connection is pressurized and closed when the upper connection is pressurized. DANGER! Always make sure that the surrounding system is de-pressurized before opening a valve to atmosphere or non-pressure vessels.

  • Page 18: Maintenance/Service

    It is recommended that the pneumatic actuators 12 (1/2”), 25 (1”) and 38 (1 ½”) are returned to Steridose for repair. Pneumatic actuators 51 (2”) and 76 (3”) are sealed and not serviceable. All plastic Pneumatic actuators and manual stainless steel actuators are also sealed and not serviceable.

    Diaphragms 4.4.1 Interval of diaphragm inspection The service life to the valve diaphragm depends on its working conditions. Important factors with regard to the service life are temperature and the type of process and CIP fluid (s). In general, inspection should be made at every 50 hours of sterilization (e.g. exposure to steam or superheated water) or 1000 hours of operation, whichever occurs first.
