Heinzmann Throttle Valves with Actuator DK 140 / StG 2040
Gas Mixing and Control Systems
HEINZMANN’s throttle valves, combined with actuators, are ideal for use as part of engine control systems. As throttle valves, they control the speed and power of gas engines by regulating the air-fuel mixture. In specialized applications, they can also be used as gas valves to regulate gas-to-air ratios. Alternatively, they can also be used as turbo bypass valves.
The devices can be installed in virtually any orientation.
The sealed throttle valve sizes, ranging from 100 to 200, cover a wide power range and are also suitable for turbocharged engines. They enable optimal engine control and a long service life. Throttle valve diameters that differ from the standard are available upon request.
The rotation angle range is 68°; rotation is possible in both directions.
