Elektrogas LMV Linear Control Valve

The Elektrogas LMV series are control valves for linear adjustment of gas or air flow in combustion systems. If you need more precise flow control than you can get from a butterfly valve, then you need a linear flow control valve like the Elektrogas LMV.

Servomotors drive LMV valves. The Elektrogas MZ3 servomotor provides 3-point step control. This means your valve has 3 positions, a min, max, and a third position dependent on when power is removed.

Similarly, coupling an LMV with an MZ5 servomotor provides continuous control. This gives you an extremely precise flow control. Information from the temperature controller drives the MZ5 in the form of an analog signal. This can be 0-10V, 0-20mA, or 4-20mA (selectable using dip switches on the MZ5). MZ5 is very easy to set up (check out our video!).

Function

The flow varies according to the opening angle of the inner cylinder, while the outer cylinder is fixed. The servomotor rotates the inner cylinder, opening or closing the gas passage. The max. flow adjustment is on the bottom of the LMV and is adjustable using an Allen key.

The expert design of the Elektrogas LMV assures low leakage, peak performance, and reliability.
