A. Makarian Co announces stock availability of the Bosch LEGV 400 for large gas and dual-fuel engine applications, including Wärtsilä 34DF engines using SOGAV 105 gas admission valves.
Piraeus, Greece — A. Makarian Co – Commercial Technical, a specialist in fuel injection systems and large-engine applications, is pleased to announce that the Bosch LEGV 400 Large Engine Gas Injection Valve is now available from stock at its premises in Piraeus, Greece.
The LEGV 400 represents Bosch technology for modern gas and dual-fuel engines and has been developed as a drop-in replacement for existing solenoid-operated valves. According to Bosch technical documentation, the valve combines proven OE technology with a hardware design suitable for many engines already in the field, addressing both new engine projects and spare-part requirements for the installed engine base.
Supporting Wärtsilä 34DF Applications
The LEGV 400 is suitable for Wärtsilä 34DF engines using SOGAV 105 gas admission valves, providing operators and technical departments with an additional solution for relevant service and replacement requirements.
Following an extensive testing procedure under demanding operating conditions, Bosch has started supplying the LEGV 400. A. Makarian Co is among the first partners to receive stock, enabling the company to provide prompt availability and technical support to its customers.

Proven Bosch Technology for Large Gas Engines
Modern gas engines are required to meet increasingly demanding targets for fuel economy, emissions, efficiency, rapid start-up and load-change capability.
The Bosch LEGV 400 has been developed specifically with these operating requirements in mind. Bosch identifies several key advantages of the design, including increased service life and reliability, OEM technology and testing, high wear resistance and multi-voltage capability.
The valve incorporates a modern hardware design, while its core valve has been developed and fully tested by several OEMs. A specific spring design and valve coating contribute to wear resistance, while the specially developed solenoid supports applications covering 24 V and 110 V engines.
