SPRING RETURN ZONE VALVE
MPE 228 / MPE2 1" - 2 PORT 28mm VALVE
Thank you for choosing a MYSON heating control.
The MPE 228 is designed to control water circulation in primary hot water or
central heating circuits. The motor is powered to open the valve with a spring
return to the closed position.
The valve is not directionally sensitive and may be fitted with flow through either
Port A or Port B.
For convenience the neon indicator light illuminates, indicating when the valve is
open.
When the manual lever is moved to the right, the valve is open. This is used when
filling, venting or draining the system. The spring return valve rests in the closed
position.
