Valves

Valves include ball, butterfly, check, globe, needle, and solenoid valves. Actuators come in pneumatic and electric; air filters have different fittings and port sizes; connectors eliminate need of welding; electro-pneumatic controllers, current/pressure transducers, positioners, and position indicators are linear or rotary operation. Volume boosters are also available.

Bulk Head Connectors Bulk Head Connectors allow for easy installation of blow tube through the dust collector wall and eliminate the need for welding of use of additional flanges. 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

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

Question

Hi-Flow™ control valves call out ANSI B16.104 Class IV flow leakage. What does this mean?

Answer

ANSI B16.104 is a testing specification for control valves. This specification has actually been superseded by ANSI/FCI 70-2 Class IV. The class IV designation defines the allowable amount of leakage through the valve seat in the closed position. Class IV allows for .01 percent of the rated flow (Cv), to pass through the seat. Class IV is common for metal to metal seated valves.

Question

What if I need parts for my Hi-Flow™ control valve?

Answer

Many Hi-Flow™ valves have been in service for 15+ years with all original parts. However, since Hi-Flow™ valves are commonly used in steam service, a severe application, some parts may wear over time. Unlike other control valves, Hi-Flow™ valves are designed with removable seat rings making repair or replacement of components an option. Although all parts are available, you will probably never need more than a seat ring, plug assembly, and stem packing to have a valve that is like new.
