The pressure regulator model BRISE PLUS manufacture by GASCAT use pilot model G-80 or G-43M+31 depending of the

desired set-point. If the set-point is greater than 2.4 bar, applies the G-43M + G31.

This pilot is responsible by the control of feed pressure of main regulator actuator and by consequence of the pressure

regulator aperture.
