Live in cold type remote control float valve is operating multiple functions of the hydraulic valves. Mainly installed in the intake or elevated water tower at the pool, when the water level reaches the height set by the main control valve closed by the float pilot valve to stop water supply intake; when the water level drops, the main valve controlled by a float pilot valve opens into outlet to pool water, automatic replenishment. Precise level control, without pressure level disturbance: piston floating remote control valve installation may vary depending on the height of the pool and the use of space anywhere, maintenance, testing, inspection convenient, reliable seal, then with a long life. Piston valves reliable performance, high strength, smooth action applies to more than 600 diameter pipeline.
