II. Instruction
The overflow valve is suitable for the occasion where the cooling | capacity requirements vary widely. It is designed to prevent the system pressure fluctuation caused by low flow rate or low density. It plays the role of constant pressure and steady flow in the system, and can be used for the control of evaporation pressure, condensing pressure, exhaust pressure etc., and has the three application functions of the overflow valve, check valve and stop valve.
III. Order Products
Please tell us the model, When ordering, the customer needs to specify the product model and pressure adjustment range.
E.g: OFD 20; 2~6.5 bar; 2 bar;
It Means: For example, OFD 20, 2~6.5 bar indicates that the pressure adjustment range of the DN20 type overflow valve is 3.5~8 bar. Factory Setting Pressure: 2 bar.
If the customer does not specify the pressure adjustment range, the default pressure adjustment range of the valve is 2 to 6.5 bar. Factory Setting Pressure: 2 bar.
