The fittings enable easy removal and re-assembly of blow tubes for cleaning and maintenance. View More Damper Actuators Damper Actuators are electric motors for positioning of dampers in HVAC systems. Low cost, two-position actuators are also non-spring return direct coupled actuators. Dwyer's models are designed to accept floating control signals and come in a variety of power supplies. View More Current to Pressure Transducers Current to Pressure Transducers in which some products are NEMA 4X enclosures, compact, low cost, and explosion-proof. Applications include valve actuators, brakes, clutches, and relays. View More Positioners Positioners for Valves that are available with HART communication for low price. Include either rotary operation or linear operation. Available with HART® communication. Dwyer's models have a durable design makes it ideal for harsh environments. View More Air Filters / Regulators This category includes filters, regulators and lubricators for pneumatic systems. Dwyer's regulators are low cost and one of the models is miniature. Variety of fittings and port sizes depending on the regulator. View More Position Indicators / Switches / Transmitters This category includes Valve Position Indicators, Position Switches, and Position Transmitters. Applications include position monitoring and indication with devices- actuators & cylinders, dampers, and rotary valves. View More Valves This category contains the different types of valves. These different types are Angle Seat, Ball, Butterfly, Check, Diaphragm, Globe, Manifold, Needle, Shuttle, Solenoid, and Zone Valves. View More Pressure to Current Transducers Pressure to Current Transducers convert a pneumatic control signal to an electrical 4 to 20 mA control signal. Dwyer models offer a high density Din Rail adapters. There is also easy plug-in installation. View More Volume Booster Volume Boosters are a one to one signal to output relay that receives the positioner’s signal output and supplies the proper air pressure to the actuator to reduce response and adjustment time. Available in aluminum or stainless steel. View More Actuators Actuators come in pneumatic and electric actuators for automating quarter-turn valves. This category contains accessories. Applications include damper control. These actuators have a compact rack-and-pinion design. Dwyer offers double acting and spring return models in a variety of sizes to fit any application. View More
