Arm-Tex is a leading distributor of FMC's Weco® butterfly valves. FMC butterfly valves have been solving fluid control problems in the oilfield and general industrial applications for over 6 decades. FMC Technologies is putting that experience to work for you in more ways than ever before- meeting your changing needs with dependable Weco® butterfly valves, operators, and actuators. The Weco® Model 12, Weco® Model 20, and Weco® Model 22 Butterfly Valves are among the most reliable, longest-lasting, and easiest to maintain butterfly valves in the market.
FMC Butterfly Valves
FMC Technologies also manufactures pneumatic vane and piston-type actuators to automate your process flow. To meet the most demanding industrial and oilfield applications. These actuators are designed and manufactured to work with their plug and check valve products. By utilizing Weco® valves and actuators, you have selected a fully integrated solution to your actuated valve needs.
The Model 200 pneumatic vane actuator is a quarter-turn, double-acting actuator and is built around a rugged two-piece die-cast aluminum housing design. This actuator requires no field lubrication, is fully repairable inline, and mounts directly to the valve in any quadrant. The model 300 and Model 500 pneumatic piston actuator is a single-piston design with 90 degrees of rotation and can be configured for double-acting pneumatic operation or fail-safe spring return.

- Weco Model 20: Reinforced design with improved durability for abrasive or high-cycle service.
- Weco Model 22: Heavy-duty butterfly valve for oilfield and severe-service environments.
Each model supports smooth operation, accessible maintenance, and a long service life, making them suitable for both manual and automated systems.
Weco Butterfly Valve Applications
A Weco Butterfly Valve supports a wide range of industrial and oilfield operations. Many facilities use these valves for loading and unloading operations, water handling, brine service, chemical injection, and general process control. The compact design makes installation simple in tight piping runs, and the quarter-turn function supports rapid opening and closing during operational changes.
Users in chemical plants, water treatment facilities, energy production sites, and industrial manufacturing rely on these valves for dependable sealing and minimal maintenance demands. The combination of seat options, body materials, and disc configurations allows operators to adapt each valve to temperature, pressure, and media requirements.
FMC Pneumatic Actuators for Weco Valves
FMC also manufactures pneumatic vane and piston-type actuators that integrate directly with Weco Butterfly Valves. This creates a complete automated valve package for systems that require reliable remote operation, consistent torque output, and accurate quarter-turn motion.
