Automatic control valve diaphragm actuated
The ON-OFF FLOAT CONTROLLED VALVE AND PRESSURE SUSTAINING, control the minimum and maximum level of a tank, allowing to maintain a minimum adjustable upstream pressure.
Controls the minimum and maximum water levels in a reservoir using a three-way float pilot. It can maintain an adjustable minimum upstream pressure and allow any excess water to transit down-stream. The two trigger levels are easily adjusted by moving the clamps on the float device arm. Adjustment is between a minimum of 10 cm to a standard value of 1m. A kit can be supplied on request to increase this interval. This type of valve is normally used on reservoirs fed by uplift systems that require intermittence, on storage tanks, booster reservoirs, or fire fighting reservoirs.
- remote control on/off switching;
- non return;
- anti-freeze option;
- flow rate limitation;
- pressure reduction with dissipation disk to control flow and prevent cavitation;
- anti water hammer resulting from very rapid closure;
- parallel pressure relief - a single valve capable of releasing over pressure generated by the closure of the float valve itself or by other upstream manoeuvres.
Available other features on request.
