Bermad 3-Way Reducing pilots. 10 bar rated plastic, 16 bar rated Brass. Standard adjustment range 1-7 bar with other spring ranges available on request.
SHARP is the most sensitive and accurate mini-pilot in the market. It is a multi-purpose 3-Way mini-pilot, diaphragm-operated, based on a balance between the hydraulic force acting on the diaphragm, and the mechanical force of the calibration spring. The pilot can be configured on valves to regulate valves for sustaining or reducing dependent on the plumbing.
The SHARP Mini-pilot sensing chamber is connected to the relevant pressure source according to application.
The SHARP directs control pressure to & from valve control chamber, by opening and closing water passages:
