Multi-way rotary valves lead Valve Type at 43.0%; Electric actuation leads Actuation at 68.0%.

Which valve type dominates?

Multi-way rotary valves are projected to account for 43.0% share in 2026.

Multi-way rotary valves are expected to lead valve type revenue because they reduce the number of separate coolant routing devices. Proportional valves are projected to serve circuits that need variable flow during charging or cabin heating. Solenoid on/off valves are estimated to retain demand where simple isolation is enough. Integrated valve modules are anticipated to gain attention when OEMs want fewer hoses and shorter assembly time.

What leads the Actuation segment?

Electric actuation is expected to hold 68.0% share in 2026.

Electric actuation is forecast to lead the actuation segment because software-controlled cooling is central to battery temperature control. Thermostatic actuation remains useful where a mechanical temperature response is acceptable. Bosch’s thermal management portfolio includes coolant proportional valves for complex switching control in preintegrated thermal modules. That product framing matches OEM interest in repeatable coolant-flow control.

How does Vehicle Type shape demand?

BEV platforms are anticipated to lead with 61.0% share in 2026.

BEV platforms are anticipated to lead vehicle type demand since they rely on battery-only propulsion and stricter pack temperature control. PHEVs are expected to need coolant routing across mixed battery and engine operating modes. Commercial EVs are estimated to use fewer units at first but require durable valves for longer daily duty cycles. The IEA said in May 2026 that electric car sales are expected to reach 23.0 million in 2026.

What supports OEM within Sales Channel?

OEM sales are estimated to represent 78.0% share in 2026.

OEM sales are projected to lead the channel mix because coolant valves are approved during vehicle platform design. Aftermarket demand is expected to form around replacement, crash repair and thermal-module service needs. Factory-fit modules are tested before launch so coolant valves can be approved with pumps, sensors and control software.

BEV thermal integration drives it; validation cost restrains it.

Drivers Impact Analysis

• BEV platform thermal integration: EV battery packs need active coolant routing during charging, driving and cabin heating. Multi-way valves are expected to reduce hose count and simplify assembly at OEM plants.
• OEM module consolidation: Module sourcing is expected to favor suppliers that combine valves with pumps and sensors. MAHLE said in May 2025 that its BEV thermal system includes HVAC, cooling, controller and coolant pump content.
• Actuator and sensor integration: Electric valves are forecast to benefit from software-controlled thermal control. Battery monitoring explains why battery pack sensors remain adjacent to coolant control.

Opportunity Impact Analysis

• Cold-weather range protection: Battery preheating and heat-pump operation are expected to increase the value of precise coolant routing. Adjacent battery conditioners show how thermal preparation is becoming a separate design need.
• Thermal manifold redesign: OEMs are anticipated to move toward fewer components around the pack. Related coolant circulation systems include valves as part of pumps, hoses and heat exchangers.

Restraints Impact Analysis

• Leak-test burden: Coolant valve approval is constrained by sealing performance under vibration and temperature cycling. Leakage risk can delay release.
• Software and actuator validation: Electric valves must respond repeatably to controller commands. Validation increases when one valve family serves several programs.
• Cost pressure in mass-market EVs: Affordable EV programs are expected to pressure valves and actuators. Suppliers must balance compact design with manufacturable parts.
