Dwyer Instruments WE01 | 2-Piece NPT stainless steel ball valve
The valve has a 316 SS (ASTM CF8M) ball for improved performance, strengthened PTFE seats and seals for extended life, and a blowout proof stem for increased safety. Direct mounting of the actuators results in a small assembly suitable for confined places. It is possible to put limit switches directly on valves, providing for distant position indication. There are two actuator configurations available for the Series WE01: electric and pneumatic. Electric actuators come with two-position or modulating control, a range of supply voltages, and are waterproof or explosion-proof. While modulating actuators use a 4 to 20 mA input for valve location, two-position actuators employ the supply voltage to push the valve open or closed. Actuators have a permanently oiled gear train and protection against thermal stress.
