DYNAQUIP CONTROLS
Frequently asked questions
Common questions about DYNAQUIP CONTROLS from 3G Electric.
What is the difference between an L-port and a T-port three-way ball valve from Dynaquip Controls?
Dynaquip Controls offers three-way ball valves with L-port and T-port flow patterns. An L-port valve directs flow from one inlet to one of two outlets, or can mix flow from two inlets into one outlet. A T-port valve allows flow from one inlet to either outlet, or can connect all three ports simultaneously. The choice depends on the required flow diversion or mixing scheme. L-port valves are commonly used for diverting flow between two lines, while T-port valves are used for more complex mixing or distribution. Both are available in stainless steel with pneumatic actuation.
What pilot solenoid voltage is available for Dynaquip Controls pneumatically actuated ball valves?
Many Dynaquip Controls pneumatically actuated ball valves are supplied with a 115V AC pilot solenoid. This solenoid interfaces with the control system to direct air to the actuator. Some models are available without a pilot solenoid, allowing the user to specify their own solenoid or use an existing air pilot signal. The solenoid voltage should match the available control power. For other voltages, consult 3G Electric for availability. The pilot solenoid is typically mounted on the actuator and can be replaced in the field.
What sizes are available for Dynaquip Controls L-port stainless steel pneumatically actuated ball valves?
Dynaquip Controls L-port stainless steel pneumatically actuated ball valves are available in sizes ranging from 1/2 inch to 2 inches. Specific models include 1/2 inch, 3/4 inch, 1 inch, 1 1/2 inch, and 2 inch. The valve size should be selected based on the pipe diameter and required flow coefficient (Cv). Larger sizes handle higher flow rates but may require larger actuators. The stainless steel body provides corrosion resistance. End connections are typically threaded, but other options may be available. Verify the pressure and temperature ratings for the specific model.
Are Dynaquip Controls pneumatic actuators double-acting or spring-return?
Dynaquip Controls pneumatic actuators are available in both double-acting and spring-return configurations. Double-acting actuators require air pressure to move the valve in both directions and will hold position on loss of air. Spring-return actuators use air to move the valve to one position and a spring to return it to the other position on loss of air, providing a fail-safe operation. The choice depends on the process safety requirements. Spring-return actuators are often used where the valve must return to a safe state (open or closed) upon air failure. Both types are available with the ball valves.
What materials are used in Dynaquip Controls actuated ball valves?
Dynaquip Controls actuated ball valves are commonly constructed with stainless steel bodies, balls, and stems. The seats and seals are typically made from PTFE or similar materials compatible with the media. Stainless steel offers good corrosion resistance for water, oils, and many chemicals. For specific media compatibility, refer to the chemical resistance charts. The actuators are typically anodized aluminum or composite materials. The pilot solenoids have brass or stainless steel bodies with elastomer seals. Always verify material compatibility with the process fluid and environment.
