Valves are blowout proof
WE33 full port 3-way stainless steel ball valves from Dwyer Instruments Inc. has a blowout proof stem, reinforced PTFE seats and seals and a ball made of 316 stainless steel, which enhances safety and performance.
Actuators are direct-mounted for compact assembly in tight spaces, while limiter switches are mountable to the valve for remote position indication. Configure the valve with electric or pneumatic actuators, which are available in weatherproof or explosion proof versions, plus a variety of supply voltages and two-position modulating control.
Two-position actuators use the supply voltage to drive the valve open or closed, and accept inputs from 4 to 20 mA for positioning.
They’re constructed of anodized and epoxy coated aluminum to provide thermal overload protection and a permanently lubricated gear train. The pneumatic double acting actuator uses an air supply to drive the valve open or closed.
The SN solenoid valve electrically switches the air supply pressure between ports for opening and closing the valve.
