Leopard membrane hydraulic valve with body in nodular cast iron. It has a smaller structural dimension; it reduces equipment weight. The new hydraulic design improves hydraulic valve KV conditions.

LEOPARD hydraulic valve

The Leopard Hydroconta valve could be configured as follows: pressure reducer, pressure sustainer, electrovalve, pressure relief, level float valve …

The LEOPARD valves ranges from DN 50 to DN 100.

  • Low maintenance
  • Optional with internal spring
  • Diameters: 2¨ – 3¨ – 3¨R – 4¨
  • Nominal pressure: PN 16

1- Why does not the valve open?

There may be insufficient pressure at the inlet pressure valve, you should examine the insulation valves of the system upstream and downstream, if they are closed open to allow the passage of water and generate pressure.
Another reason may be that the solenoid is calcified, clean it and replace parts as necessary.

2- Why does not the valve regulate at the desired control point?

It may be caused by the pilot because it is not adjusted properly, check it by tightening and loosening the screwdriver to see if there is a pilot reaction, so you can adjust the pilot to the desired opening and closing speed.
Check if the upstream filter is clogged and causes insufficient pressure to reach the pilot to activate the valve at the desired control point.

3- Why does not the valve close?

It may be that the filter is clogged, to check it, disconnect the copper line from the lid to see if there is water flow in the inlet. In this case clean the filter mesh.
If the main valve membrane fails, it can also give this result, replace the membrane for repair.
Another reason may be that the solenoid is calcified, clean it and replace parts as necessary.

4- Why does the membrane leak water?

It is usually produced by the accumulation of dirt between the membrane and its closing support, closing the valve manually, if the problem persists open the valve to clean the area.
