SERIES WE04 | 2-PIECE FLANGED STAINLESS STEEL BALL VALVE
®
FEATURES/BENEFITS
• Eliminates threads and reduces installation and maintenance time
• Vented ball to reduce operating torque
• Full port design reduces the pressure drop across the value
• Limit switches can be mounted to manual valves for remote monitoring
• Weatherproof or explosion-proof electric actuators
• Double acting or spring return anodized aluminum pneumatic actuators
APPLICATIONS
• Gas or liquid ow control
• Ideal for quick bubble tight shut-off
DESCRIPTION
The SERIES WE04 incorporates a full port 2-piece anged SS ball valve for great ow
rates with minimal pressure drop. The valve features a blowout proof stem for added safety,
reinforced PTFE seats and seals for longer life, and a 316 SS (ASTM CF8M) ball for better
performance. Actuators are direct mounted creating a compact assembly for tight spaces.
Limit switches are able to be mounted directly to the valves allowing for remote position
indication. The Series WE04 can be congured with either a pneumatic or electric actuator.
Electric actuators are available in weatherproof or explosion-proof, a variety of supply
voltages, and two-position or modulating control. Two-position actuators use the supply
voltage to drive the valve open or closed, while the modulating actuator accepts a 4 to 20 mA
input for valve positioning. Actuators feature thermal overload protection and permanently
lubricated gear train. The pneumatic double acting actuator uses an air supply to drive the
valve open and closed. The actuator has two supply ports, with one driving the valve open,
and the other driving the valve closed. Spring return pneumatic actuators use the air supply
to open the valve, and internally loaded springs return the valve to the closed position. Also
available is the SN solenoid valve to electrically switch the air supply pressure between the
air supply ports for opening and closing the valve. Actuators are constructed of anodized and
epoxy coated aluminum for years of corrosion free service.
