Frequently Asked Questions

Q: What is the main difference between the diaphragm and piston control chambers?

Diaphragm chambers are best for clean media and noise-sensitive areas (like HVAC) providing smoother regulation. Piston chambers are designed for high-pressure, high-temperature, or abrasive fluids (like wastewater) due to their robust mechanical strength.

Q: How does this valve prevent water hammer during pump shutdown?

It uses a two-stage closing mechanism: the main disc closes quickly to stop flow, followed by a gradual closure of the pilot valve (3-120s), which slowly dissipates pressure and prevents destructive shock waves.

Q: Can this valve handle fluids with small solids or particles?

Yes, specifically the piston-type model with a hard-chrome-plated surface is engineered to resist scratches from sand, scale, or sludge, ensuring a long cycle life in abrasive environments.

Q: What are the typical applications for the multifunctional pump control valve?

It is ideally suited for high-rise building water supply systems, municipal water distribution, industrial cooling systems, and any pumping station requiring combined isolation and surge protection.

Q: What is the maximum working pressure and diameter available?

The valves are available in nominal calibers from DN50 to DN1400 and can handle working pressures from 1.0MPa up to 10.0MPa.

Q: Is the slow-closing time adjustable?

Yes, the slow-closing time can be precisely adjusted between 3 and 120 seconds using the external accessories and piping to meet the specific hydraulic needs of your system.
