WE03-DHD00

WE03-DDA01 WE03-DDA01-AA06

The Series WE03 3-Piece Tri-Clamp Stainless Steel Ball Valves incorporate a full

port 3-piece tri-clamp 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 WE03 can be congured with either an electric or pneumatic 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.

Valves,

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.

FEATURES/BENEFITS

• Capable of being congured to t any application

• Limit switches can be mounted to manual valves for remote monitoring

• Cavity lled valve for sanitary applications

• Weatherproof or explosion-proof electric actuators

• Double acting or spring return anodized aluminum pneumatic actuators

• Full port design reduces the pressure drop across the valve

APPLICATIONS

• Gas or liquid ow control

• Ideal for quick bubble tight shut-off

• Designed for food and beverage applications
