CRE4 Series ESD Pneumatic Valves, 1/4" Orifice, 2-way, Normally Closed Luer
- Flammable solvents and other nonconductive semiconductor chemistries
- High-purity corrosive chemical handling
- All semiconductor wet etch and clean (WEC) process chemicals
- Chemical line sizes 3/8" or smaller
仕様書
Durable Valves for Harsh Environments
- With no exposed metal hardware, the CR4 Series valve is completely sealed and protected from harsh chemical environments
- The modular design enables manifold customization into your fluid delivery system
- Designed with the same footprint as our stand-alone and manifold Galtek® SG Series valves and Dymension® valve manifolds, allowing for easy retrofits or replacement

Port Connection | Flow Factor CV | Flow Factor KV | A | B |
1/4" PrimeLock | 0.34 | 4.9 | 3.18" (80.8 mm) | 0.51" (13.0 mm) |
3/8" PrimeLock | 0.84 | 12.0 | 3.18" (80.8 mm) | 0.61" (15.5 mm) |
Restricted Open or Restricted Closed (shown in 5th 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
Sensing Option Dimensional Information (shown in 6th 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.
