MG series controls various gas supply line pressure such as city gas, the natural gas with excellent response and high security. Serialized widely them for from low pressure to high pressure, and low noise governor.
Excellent response and controllability
High sensitivity pilot has been adopted and it responses to a slight pressure fluctuation with little setting error. In addition, stable control can be made even to sudden load fluctuation.
Excellent features even at low pressure
Stable control is allowed from minute flow rate to large flow rate with a small cutoff pressure, and less than 9.8 kPa offset at the fully-closing time depending on the type.
Safety design of non-bleed type
The structure is designed to allow the pilots bleed gas to release to the outlet side of the governor. It is safety since no gas is released to the atmosphere.
The body has a rigid structure with single seat valve of the cage guide type. In addition, the internal parts are the pressure balancing type that allows stable control even at high pressure with a small reaction of the fluid.
Easy reduction of noise
By only replacing the internal part of the standard governor, the governor can be easily remodeled into a low noise governor. (Noise can be reduced by about 20 dB compared with the standard governor.)
