AutoFill boiler feeder

Yuhuan Tino Imp&Exp Co., Ltd is complex of producer and trading company , mainly producing kinds of safety valves,  T61M seriese for electric water heater, T611-614 for wall-hung boiler and central heating system,  61T1-61T2 is designed for pressure vessel such as solar water heater, any steam tank ,which need control temperature and pressure.And Automatic air vent including solar air vent, home appliance water pressure reducing valve. And other brass fitting. 

Function
Automatic filling valve is the device consisting of a pressure reducing valve with compensating seat, check valve(installed in outlet of the valve,optional). And installed generally onto supplying pipe in sealed circulating heating or refrigerating system, it maintains the pressure of the system stable at a set value and prevent water-back flow happening, or automaticaly fills up water into supplying 
device or end user device when pressure differential happens between upstream and downstream

This valve is characteristic of being pre-adjustable, it can be adjusted at the pressure value before installed in system(better read pressure via pressure gauge as optional)
