1For CR8 valves with tube pilot port configurations and PureBond weld lengths less than standard, we recommend rotated pilot port options P2 and P4.
Sensing Option Dimensional Information (shown in 5th drawing above)
A Remote Position Indication option is available to monitor valve open and closed positions electronically.
Note: To enable the remote position indication option you must special order the Omron® sensor (-OM) on the valve. In addition, order Omron® position sensor indicator (EE-SX771R or EE-SX771A), which are sold separately.
Restricted Open or Restricted Closed (shown in 6th drawing above)
Note: Height dimension includes stem in open position
- Restricted open option allows for a manual variable limit control on the open travel of a pneumatically controlled valve
- Restricted closed option allows for a manual variable limit control on the closed travel of a pneumatically controlled valve
- Both options are offered in normally closed and normally open pneumatic actuators
