Dwyer Instruments WE01 | 2-Piece NPT stainless steel ball valve
Genuine Dwyer Series WE01 ball valve from General Tech Services LLC, Saudi Arabia, with free Saudi Arabia shipping available.
Part No. WE01
Product Overview
The Dwyer Series WE01 is a 2-piece stainless steel ball valve with female NPT end connections for process isolation and control applications. Its full-port design provides high flow with minimal pressure drop, while the blowout-proof stem, reinforced PTFE (RTFE) seats and PTFE seals and packing support reliable operation.
The valve uses a 316 stainless steel (CF8M) ball and is available in line sizes from 1/2 to 3 inches. Pressure limits are 28" Hg to 1000 psi (-0.7 to 69 bar) up to 250°F, with a temperature range of -29 to 200°C (-20 to 392°F), subject to the exact valve size and configuration.
The WE01 can be supplied as a manual valve or configured with direct-mounted electric or pneumatic actuators. Electric actuator options include weatherproof or explosion-proof versions, various supply voltages, two-position control and 4–20 mA modulating control. Electric configurations also include thermal overload protection and a permanently lubricated gear train.
Pneumatic actuator options include double-acting versions with 40–115 psi supply and spring-return versions with 80 psi supply, with a maximum pneumatic supply of 120 psi. Actuators mount directly to the valve to create a compact assembly, while limit switches can be fitted directly to the valve for remote position indication, including manual configurations.

Frequently Asked Questions
What is the Dwyer Series WE01?
The Dwyer Series WE01 is a 2-piece NPT stainless steel ball valve from Dwyer/W.E. Anderson for process isolation and control.
What end connections does the WE01 have?
The WE01 uses female NPT end connections.
What sizes are available?
The supplied specifications list line sizes from 1/2 to 3 inches. The exact model should be confirmed according to the required size and configuration.
Is the WE01 a full-port valve?
Yes. The WE01 uses a full-port design intended to provide high flow with minimal pressure drop.
What pressure and temperature ranges does it support?
The supplied specifications list pressure limits of 28" Hg to 1000 psi (-0.7 to 69 bar) up to 250°F, and temperature limits of -29 to 200°C (-20 to 392°F). Actual ratings depend on the exact size and configuration.
Can the WE01 be automated?
Yes. It can be supplied as a manual valve or configured with direct-mounted electric or pneumatic actuators.
What control options are available with electric actuators?
Electric actuator configurations support two-position control or 4–20 mA modulating control. Weatherproof and explosion-proof versions are available depending on configuration.
What pneumatic actuator options are available?
The available configurations include double-acting actuators with 40–115 psi supply and spring-return actuators with 80 psi supply. Maximum pneumatic supply is 120 psi.
Can I add position feedback?
Yes. Limit switches can be mounted directly to the valve for remote position indication, including on manual versions.
What is the difference between the WE01 and WE06?
The WE01 is a 2-piece NPT stainless steel ball valve, while the WE06 is a 3-piece NPT stainless steel V-ball valve. The appropriate series depends on the required valve body design, flow-control requirements and application.
