KVS 4-way diverter valve for gas and oil applications

A 4-way diverter valve for gas and oil applications is a specialized component used to change the direction of flow in pipelines and systems. These valves are critical for managing custody transfers, meter proving, and multi-product systems in the oil and gas industry

Common applications

• Metering systems: A primary use is in bi-directional meter proving systems, which verify the accuracy of flow meters. The valves rapidly cycle to reverse the flow of fluid, and their tight shut-off guarantees precise measurement.


• Multi-product manifolds: In tank farms and terminals, they are used to direct different types of hydrocarbons from storage tanks into loading systems.


• Product blending and loading: They facilitate the transfer of different gas or oil products during blending or loading operations.


• Transport pipelines: In pipeline systems, these valves can be used to redirect flow for maintenance, sampling, or custody transfer.


• Airport fueling: Their high-speed and reliable operation make them suitable for use in aviation fueling systems.


• Essential for efficiently directing different fuel types into transport vehicles or fuel systems


• Custody transfer and metering systems: Used at points where ownership of a product changes, such as with Lease Automatic Custody Transfer (LACT) units.

Key features

• Zero leakage: Many designs feature a "bubble-tight" seal, which is provable and provides 100% tight shutoff to ensure accurate measurement and prevent product mixing.


• Friction-free operation: Some valves use a retracting-slip mechanism, where seals pull away from the valve body before rotating. This prevents friction and abrasion, increasing seal life.


• Fast operation: Designed for frequent and rapid cycling, with some models able to complete a cycle in 4–10 seconds for high-frequency operations like meter proving.


• In-line maintenance: Many models are designed for easy maintenance, with features that allow for the exchange of seals or other components while the valve is still in the pipeline.


• Durable materials: For oil and gas service, valves are constructed from robust materials such as carbon steel, stainless steel, and other alloys to handle high pressures, temperatures, and corrosive fluids.


• High pressure ratings: Valves are manufactured to withstand the high operating pressures common in the oil and gas industry

Important standards and specifications

• API 6D: An industry standard for pipeline valves, ensuring the valve is suitable for use in the demanding conditions of oil and gas pipelines.


• ASME B16.34 / B16.5: These standards cover the design, dimensions, and pressure ratings for valves, flanges, and fittings.


• Fire-safe design (API 6FA):A certification that ensures the valve will maintain its integrity and prevent leakage in the event of a fire.


• Material compatibility: Valves are available in a variety of materials to ensure compatibility with different types of oil and gas, as well as corrosive fluid
