Stainless Steel Ball Valve has automated 3-piece tri-clamp design.

Press Release Summary:

For optimal flow with minimal pressure drop, Series WE03 incorporates full port 3-piece tri-clamp stainless steel ball valve. Blowout-proof stem promotes safety, reinforced PTFE seats and seals lend to extended life, and 316SS (ASTM CF8M) ball maximizes performance. Configurations are available with electric or pneumatic actuators, which are direct mounted and create compact assembly for tight spaces. Limit switches can be mounted directly to valves and allow remote position indication.

Original Press Release:

NEW! Series WE03 3-Piece Tri-Clamp Stainless Steel Ball Valve

W.E. Anderson a division of Dwyer Instruments Inc., the preferred source for your complete range of practical instrumentation, is announcing the release of its NEW SERIES WE03 AUTOMATED 3-PIECE TRI-CLAMP STAINLESS STEEL BALL VALVE.

The Series WE03 incorporates a full port 3-piece tri-clamp stainless steel ball valve for great flow 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 316SS (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 configured with either an electric or pneumatic actuator. Electric actuators are available in weatherproof or explosion-proof, a variety of supply voltages and two-position modulating control. Two-position actuators use the supply voltage to drive the valve open or closed, while the modulating actuator accepts a 4 to 20mA 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.
