Principle

 

Piston control valves consist of valve body, seat, piston, valve shaft, crank, connecting rod, driven pin, cone pin, bearing and operating mechanism. Piston valve through a connecting rod piston valve spindle rotation can be converted to axial movement along the guide rail, in the process of the piston back and forth motion, by changing the area of circulation between the piston and the valve seat to realize the flow control and pressure control. The flow from the axial arc to the valve body, the flow in the piston control valve is axisymmetric, and the flow will not generate turbulence. No matter the piston movement to any places, regardless of any position of cavity flow cross-section are ring, at the exit to the axis of contraction, so as to achieve the best cavitation, avoid because of throttling and possible cavitation damage to the valve and pipe.

 

 

Features and benefits

  1. Linear adjustment: valve opening and flow is linear, can achieve accurate regulating purposes.
  2. Low maintenance cost: reasonable passage design and material ensure the long lifetime.
  3. Low torque: hydraulic balance design, combining with copper guide bar surfacing, makes eh piston operation more stable and reliable.
  4. Easy installation: Any direction is workable for the valves, and bidirectional seal makes it easier to install.
  5. Water hammer & vibration resistant: there are uniform spiral holes around the sleeve, which can absorb the energy of water hammer. Can reduce the vibration caused by high pressure differential.
  6. Versatility: can be used to replace hydraulic diaphragm control valve and Y-type control valve.
