bypassklep

A bypassklep, or bypass valve, is a valve that provides an alternative path for fluid to bypass a part of a system. By creating or closing this path, it allows management of flow, pressure, temperature, and maintenance operations without completely shutting down the system. Bypassklep can be installed in plumbing, heating, cooling, automotive, and industrial process systems.

In operation, a bypassklep either diverts flow away from a component, such as a heat exchanger, radiator, or turbocharger, or allows mixing of streams to achieve a desired condition. The valve is commonly controlled by manual operation, a solenoid or actuator, hydraulic or pneumatic pressure, or electronic control logic. Two-way and three-way configurations are common; three-way valves can combine or split flows to regulate temperature or pressure.

Applications

- Plumbing and heating: a bypassklep maintains flow and pressure when a radiator or valve is closed, prevents pump cavitation, and helps regulate return temperature.

- Automotive: turbocharger bypass valves relieve compressor pressure when throttle rapidly closes, preventing surge. They can be vent-to-atmosphere or recirculating types and are often controlled by vacuum or electronic actuators.

- HVAC and industrial processes: bypasskleppen blend hot and cold streams to meet setpoints or isolate for maintenance.

Design considerations include material compatibility with the fluid, pressure and temperature ratings, leak tightness, response time, and fail-safe behavior. Proper sizing and placement reduce flow disruptions and ensure safe operation.
