Product description
Body and cap: ductile iron
Valve seat and valve disc: brass
Valve stem: stainless steel
Spring: stainless steel
Surface: epoxy
Valve sealing: NBR
Consist of main valve, needle valve, ball valve, floating ball valve, micro filter as hydraulic control to take over system and automatic control of liquid level
Direct use of liquid level control, no other devices and energy, maintenance is simple, liquid level control, high accuracy, not subject to water pressure affect reliable sealing
Widely used for level control of towers, pool and other facilities, high rise building, living area and water supply systems
Working principles:
Pipeline from influent water supply, due to needle valve, ball valve, floating ball valve is normally open, water through micro filter, needle valve, control room, ball valve, float valve into pool, control room does not formation pressure, open main valve and water tower (pool) water supply
Towers (pool) water rises to set height, float to close float valve to control indoor water pressure and promote main valve closed, water supply stops
Water drops, float valve re-open control room pressure drop, main valve to open again to continue water supply to maintain liquid level of set height
