Leopard with accessories

LEOPARD hydraulic diaphragm valve with accessories. These valves are designed to open and close water flow through a 3 ways valve.

Leopard Hydraulic valve with accesories

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

Applications
  • Leopard diaphragm hydraulic valves are designed to open and close water flow manually through a 3 ways valve.

Functioning

The installed 3 ways vale allow to act in different functional modes:

  • Automatic (A): The water located in the chamber communicates with the reducer and sustainer pilot that will operate and do its function.
  • Open (O): The water in the chamber is drained through the pilot in both solenoid and non-solenoid assembling. As result the pilot will not work so the valve will be totally open.
  • Closed (C): The water in the chamber will communicate with the inlet water. As result the valve will be totally close.

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.
