Hydraulic valves

PN10 plastic hydraulic valves

Plastic hydraulic valves are used for many irrigation applications:

  • Electric valve

  • Pressure regulation

  • Upstream pressure stabilizers

  • Float valve etc.

Operation

The valve opens or closes hydraulically depending on the pressure exerted on the upper part of a rubber diaphragm. If the pressure on the diaphragm is at least equal to or greater than the upstream pressure, the valve closes. If the pressure on the diaphragm is lower than the upstream pressure, the valve opens. Possibility of regulating the downstream pressure of a pipe by varying the volume of water in the chamber of the membrane. It is also possible to control the valve using an external fluid (air, water, etc.).

Hydraulic valves cast iron PN16

Cast iron hydraulic valves are available with several types of connection (BSP or NPT threaded, victaulic type grooved, flanged) and can have several operating modes depending on the accessories mounted on the valve.

  • Electric valve

  • Upstream, downstream, discharge pressure regulation

  • Flow regulation

  • Float valve etc.
