Steam Water Mixing Battery (SWB-IA Series)
The battery comprises of mixing valve with spring and a piston, which moves to the left to open the steam inlet valve. Holes on piston are exposed to allow water to enter the mixing chamber and mix with the steam. If at any time the water pressure fails or the outlet is closed, steam pressure causes the piston to move to the right and the steam inlet valves closes. Non return valves are fitted in the inlet connections to prevent water entering the steam supply, and vice versa. A minimum water supply pressure of 2 bar is required to give a reasonable hot water spray velocity at the outlet of spray gun. Steam pressure should always be greater than the water pressure by minimum 1 bar.
