Series WE35 3-Way NPT Brass Ball Valve
Specifications - Installation and Operating Instructions
Bulletin V-WE35
The
Series WE35 3-Way NPT Brass Ball Valve
incorporates a full port 3-way brass
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
brass ball for better performance. Actuators are direct mounted creating a compact
assembly for tight spaces.
The Series WE35 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 or modulating control. Two-position actuators use the
supply voltage to drive the valve open or closed, while the modulating actuator accepts
a 4-20 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.
