German Precision.
US-Based Support.
RTK — a CIRCOR International brand manufactured in Kornwestheim, Germany — has nearly 40 years of experience engineering control valves for the most demanding industrial applications. From compact HVAC control to heavy-duty steam conditioning, RTK delivers precision, reliability, and long service life.
As the authorized US dealer, ICA provides the complete RTK product line with domestic support — factory-direct pricing, application engineering, valve sizing with RTK-Calc software, complete actuated assemblies, commissioning, and a local parts inventory so you never wait on overseas shipments.
The RTK range covers motorized control valves (electric and pneumatic), REact electric actuators, ST pneumatic actuators, steam-converting valves, desuperheaters, feed-water and blowdown valves, self-operating pressure regulators, manual stop valves, and strainers.
Compact motorized control valves for throttling, mixing, and diverting of liquids and gases. The MV 52 pairs with REact electric actuators (up to 3 kN), while the PV 62 uses pneumatic actuators with 280 cm² diaphragm area. Available in two-way and three-way configurations for maximum piping flexibility.
- Electric: MV 52 — REact actuators up to 3 kN
- Pneumatic: PV 62 — 280 cm² diaphragm, <10 kN force
- Designs: Two-way and three-way configurations
- Function: Throttling, mixing, and diverting
- Media: Liquids and gases
Mid-range control valves delivering higher actuation forces for larger valve bodies and higher-pressure applications. The MV 53 accepts REact electric actuators rated 6–10 kN, while the PV 63 pneumatic variant provides 530 cm² diaphragm area. Ideal for medium-duty HVAC, process, and steam applications.
- Electric: MV 53 — REact actuators 6–10 kN
- Pneumatic: PV 63 — 530 cm² diaphragm, <10 kN force
- Designs: Two-way and three-way configurations
- Function: Throttling, mixing, and diverting
- Application: HVAC, process control, steam systems
The largest standard control valve series in the RTK line — built for high-flow, high-pressure industrial applications. The MV 54 accepts REact electric actuators rated 6–10 kN, while the PV 64 pneumatic variant delivers up to 56 kN actuation force with a 1000 cm² diaphragm area.
- Electric: MV 54 — REact actuators 6–10 kN
- Pneumatic: PV 64 — 1000 cm² diaphragm, up to 56 kN
- Designs: Two-way and three-way configurations
- Function: Heavy-duty throttling, mixing, diverting
- Application: Industrial process, power generation
The REact series covers the full range of electric actuation — from compact REact 15 (1.5 kN) to the heavy-duty REact 300 (30 kN). All models feature precise positioning, diagnostic feedback, and optional REpos positioner, REdrive gear unit, and REacTron electronic controller accessories.
- Range: REact 15, 30, 60, 100, 150, 220, 300
- Force: 1.5 kN to 30 kN actuation force
- Accessories: REpos, REdrive, REacTron
- Controls: Precise positioning with diagnostics
Diaphragm-type pneumatic actuators sized for every valve in the RTK control valve line. From the compact ST 6115 (120 cm²) through the heavy-duty ST 6175 (1000 cm²), each model delivers reliable, fail-safe actuation with optional SR positioner and limit switch accessories.
- Range: ST 6115, 6135, 6160, 6175
- Diaphragm: 120 cm² to 1000 cm² effective area
- Accessories: SR 6136, SR 6139, SR 3300
- Operation: Fail-safe capable, spring-return
Reduce steam pressure while simultaneously cooling — combining pressure reduction and desuperheating in a single valve body.
Precision steam temperature and pressure control via multi-nozzle water injection lance design.
Designed for high differential pressure service — controlling water injection flow for steam conditioning systems.
Boiler feed-water regulation with integrated recirculation connections for continuous and intermittent service.
Continuous and bottom blowdown valves for boiler water chemistry management and sediment removal.
Cage-guided globe valve construction for severe-service applications requiring tight shutoff and precise control.
Noise reduction after throttling — separate designs optimized for liquid media and gas/vapor media.
Electric control valves with pneumatic fail-safe closure — two-way and three-way designs for MV 52/53/54 series.
Regulators, Stop Valves
& Strainers
Self-operating pressure regulators, bellows-sealed manual stop valves, and pipeline strainers — completing the RTK system from source to point of use.
Pressure and excess pressure regulators that operate without auxiliary energy — simple, reliable pressure control for steam, water, and gas systems.
Relief valve protection for overpressure scenarios — self-operating design requires no external power source.
Bellows-sealed manual stop valves for water, steam, air, and thermal oil service up to 400°C. Zero-emission seal design.
Pipeline strainers that protect downstream equipment from solid debris — essential for control valve longevity.
