HOW CAN I CHOOSE THE CORRECT BY-PASS VALVE?

PRESSURE AND FLOW RATE

The by-pass valve must be proportionate to the pressure and flow rate parameters to be obtained depending on the available pump. During the choice it is advisable to orientate oneself on valves that can contain the performance of the system with a little margin, in order to make the circuit as efficient as possible, avoiding load losses.

 

TEMPERATURE

As with piston pumps, in addition to the flow rate and pressure, it is essential to focus on the working temperature. There are valves specially designed to work at high temperatures.

 

CONSTRUCTION MATERIALS

Finally it is essential to take construction materials into consideration. Brass and stainless steel are the construction materials used to make the bodies and internal components of the valves offered by emiltec. Aisi 316 stainless steel is indispensable when working with salt water, demineralised water or more generally with solutions that involve mixing water with aggressive substances.
