Leopard Basic hydraulic valve

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

Leopard valves are available from DN 20 to DN 300 diameter.

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 Basic hydraulic valve

Las válvulas hidráulicas de membrana o diafragma son básicos imprescindibles en cualquier instalación. Hidroconta ofrece la gama Leopard, se trata de una válvula de diseño único desarrollada íntegramente por el equipo de Hidroconta que puede ser configurada según los requerimientos de cualquier instalación. Con cuerpo en fundición la válvula hidráulica Leopard la puedes encontrar en varios calibres y conexiones, rosca y brida.


Hydraulic membrane or diaphragm valve.

  • During operation, it uses the energy of the circulating fluid, with a single activation chamber, which is closed by the diaphragm. All parts together form a conduit through which the water will flow, which we will “strangle” through the diaphragm, as needed.

Low load losses

  • Hidroconta’s Leopard hydraulic valve has been designed to prevent pressure surges caused by its slow opening and closing process. In addition, its hydrodynamic design reduces any possible internal turbulences and its body generates low load losses.

Low maintenance

  • Its simple construction system, with few moving parts, allows on-site maintenance without the need to disassemble the installation, in addition to guaranteeing a long useful life. An internal spring can be fitted to force the hydraulic valve open, although this is optional and not always required.

Improved design

  • The new Leopard membrane valve design has improved the kV that the valve can handle. In addition, a reduced body size has also allowed the improvement of its characteristics, reducing the unit’s weight.


  • Membrane valves are required in any water installation, since these are multipurpose elements. Leopard valves can be configured upon the customer’s request as a pressure reduction, solenoid, flow limiter, quick pressure relief or flow rate accelerator valve, in addition to allowing other adjustment and multipurpose options.

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.
