CRE4 Series ESD Pneumatic Valves, 1/4" Orifice, 2-way, Normally Closed Luer

Download Image

CRE4 Series valves are the smallest conductive PFA valves available for high-purity chemical handling in line sizes 3/8” and smaller. The pneumatic actuator Luer design offers an alternative pilot air connection, which is a proven and reliable connection commonly used in the medical industry.

Conductive PFA valve body mitigates ESD by safely dissipating electrical potential when properly grounded
PrimeLock® ESD connections offer clean, high-performance and easy make-up to facilitate ESD system connectivity and continuity
Small footprint preserves valuable space on OEM equipment
All wetted parts are PFA, providing corrosion resistance in harsh chemical and high-purity environments
Valve diaphragms successfully tested to over 2.1 million cycles for increased reliability
Stand alone mounting base enables valve installation and removal without tools

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

			Dimensions
Port Connection	Flow Factor C_V	Flow Factor K_V	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.
