Zhuzhou - Multifunctional Tilting-Disc Valve

SHARE

Installed not only in water-intake, water delivery, pressurizing, submersible, and sewage pumping stations in municipal, construction, steel, metallurgy, petroleum, chemical, food, pharmaceutical, power, water conservancy and irrigation industry , but also in delivery system of oil & chemical fluid. The valve has 3 functions as electric driving valve, check valve and water hammer eliminator, which can effectively improve security and reliability of the system, and meet the requirements for automatic control and energy saving.

  1. High safety and reliability: this valve has 3 methods for water hammer erasing as rapid-close, slow-close, and energy-absorbing cavity. The valve operation is interlocked without malfunction.
  2. No manual control. When the pump is started or closed, the driving force is the pressure difference of the medium before and after the valve. In this way, the valve is operated automatically in accordance with the requirements of the pump’s service manual.
  3. No specialized debugging. Valve movements are not affected by liquid height difference, discharge pressure, and pump’s flow changes, to adapt to a wide range.
  4. Basically no maintenance, long life.
  5. Energy-saving, flow resistance similar to butterfly valve.
  6. Short structure length, light weight, easy installation and line maintenance.
  1. Nominal pressure: 1.0MPa, 1.6MPa, 2.5Mpa
  2. The minimum operating pressure: 0.05MPa
  3. Applicable medium: raw water, water, sewage, oil
  4. Applicable temperature: 0 ~ 80 ℃
  5. Slowly-closing time: 10 ~ 120s (adjustable)
  6. Water hammer peak value: ≤ 1.5 times the rated pressure of in pump outlet
  7. Pump maximum reverse speed: ≤ 1.2 times the rated speed
  8. Resistance loss: approaching normal butterfly valve
  9. Diaphragm fatigue bending: 200 million times without damage
