Scott Equipment Company supports Enfield Technologies proportional valves, servo-pneumatic positioning systems, electronic pressure regulators and precision flow-control products for manufacturers, OEMs and machine builders throughout North and South Carolina.
Enfield Technologies Proportional Pneumatic Control Systems
Enfield Technologies specializes in high-performance proportional control systems. Its standard product line focuses on pneumatics, with current products for pressure, position and flow control including proportional valves, servo-pneumatic cylinder positioning systems, electronic pressure regulators, motorized needle valves and proportional pinch valves.
High-Performance Proportional Control for Pneumatic Systems
Enfield Technologies is based in Trumbull, Connecticut and describes itself as an expert in high-performance proportional control systems. While its standard product portfolio is focused on pneumatics, Enfield also applies its engineering expertise to other fluid-power, electromechanical and control-electronics applications through custom products and engineering services.
Pressure, Position & Flow Control
Enfield’s current product architecture is built around controlling continuously variable pneumatic and fluid-process functions rather than simply switching them on or off.
Fast Proportional Valve Technology
High-speed proportional valves and embedded electronics support applications requiring rapid response, smooth modulation and repeatable control beyond conventional on/off pneumatic operation.
Integrated Servo-Pneumatic Systems
Enfield combines proportional valves, sensing and control electronics to create pneumatic systems capable of intermediate positioning, controlled motion and other closed-loop functions.
Explore Enfield Proportional Control Products
Use these current Enfield product areas as a starting point for proportional pressure, position and flow-control applications in industrial automation, test equipment, packaging, process systems and specialty machinery.
2/2 Proportional Valves
Enfield’s 2/2 valve families include PFV proportional solenoid valves for liquid and gas flow control, RCV low-pressure/high-flow servo proportional valves and VQV pressure-compensated proportional valves. PFV configurations are also available with onboard linear drivers.
Explore 2/2 proportional valves →5/3 Proportional Directional Valves
Current 5-port, 3-position proportional pneumatic valve families include ECS, ELB, Enfinity® and LS Series products. Enfield states that its 5/3 proportional directional valves provide response times under 3 ms, supporting high-speed open-loop and closed-loop pneumatic control.
Explore 5/3 proportional valves →S2 Cylinder Positioning Systems
The S2 servo-pneumatic positioning system combines a proportional valve, sensors and embedded control electronics to position linear or rotary pneumatic actuators from a PLC. It can stop cylinders at unlimited midstroke positions, follow motion profiles or reduce hard end-of-stroke impacts.
Explore S2 positioning systems →TR Electronic Pressure Regulators
TR proportional electro-pneumatic regulators convert voltage or current commands into proportional pressure output. Enfield specifies response times as fast as 2.5 ms and accuracy of ±0.1%, with direct-acting voice-coil technology supporting control from vacuum through 145 psig on current products.
Explore TR pressure regulators →ENV Motorized Needle Valves
ENV 2/2 motorized needle valves combine stepper-motor positioning with needle-valve flow control for repeatable proportional adjustment of liquids and gases. Current configurations include aluminum and stainless-steel bodies with multiple seal-material options.
Explore motorized needle valves →EQV Proportional Pinch Valves
EQV proportional pinch valves regulate liquid or gas flow by squeezing flexible tubing from the outside. Because the valve mechanism does not contact the media, Enfield positions the series for hygienic, high-purity, sanitary and corrosive-fluid applications requiring media isolation.

Our Sales and Technical Teams can help review pressure, position, flow and force-control requirements; response and accuracy targets; actuator sizing; available compressed air; feedback sensing; command signals and PLC architecture. We can also coordinate Enfield products with cylinders, sensors, air preparation, controls and supporting pneumatic components.
Proportional Valve Selection
Match valve architecture, media, pressure range, flow, response time, command signal and closed-loop requirements to the appropriate 2/2 or 5/3 valve family.
Servo-Pneumatic Positioning
Review cylinder bore and stroke, load, speed, position accuracy, sensor technology and PLC interface for S2 positioning applications.
Pressure & Flow Control
Compare TR regulators, proportional valves, motorized needle valves and pinch valves based on controlled variable, media isolation, accuracy, speed and operating range.
WBIYII Pneumatic Assemblies
Coordinate Enfield valves, regulators, sensors, manifolds, air preparation, cabling and related controls into repeatable WBIYII assemblies or installation-ready kits.
Selection note: Final proportional-control performance depends on the complete system, including valve sizing, supply pressure and flow, downstream volume, actuator dynamics, sensor quality, command-signal resolution, tubing, air preparation and control-loop tuning. Application-specific performance should be verified using the actual operating conditions and Enfield product documentation.
