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
