FLOAT VALVE

Float valve uses a sub-valve ( floating ball switch ) to control the main valve.
Wneh the water level elevates to the full water level set by sub-valve (floating ball switch), the sub-valve ( floating ball switch ) closes and back pressure chamber inside the main valve accumulates pressure rapidly, which reversely pushes the piston valve to close.
By this mechanism, the float vlave can thus control the water level. In oder to save space inside the pool and for easy maintenance, it is recommended to install the float valve outside the pool.

  At full water level, pressure accumulates
in the pressure chamber and pushes
the gate reversibly.		 At low water level, pressure chamber
dissipates, and water pressure inside
the pipe pushes the gate open.
  • The working pressure should be greater than 0.3kgf/cm2 ,please check the pressure before installation.
  • Please remove impurities or metal dusts inside the pipe thoroughly.IF possible, please add filter to
    prevent pipe blocking.
  • Vertical and horizontal installation is acceptable. Avoid upside-down installation under insufficient flow.
  • Please uses high pressure float ball switch.

PRESSURE REDUCING VALVE
  • Pressure reducing balve can prevent pipeline breakage due to high pressure.
  • Pressure reducing valve is installed in water supply pipeline and maintains the
    setting outlet pressure in main valve, regardless of teh different inlet pressure.
  • Pressure reducing valve can be installed in water supply, air conditioning and
    fire control systems to maintain the setting outlet pressure.

The pressure reducing valve uses a sub-vales(pressure reducing pilot valve ) to control the main valve. When the outlet pressure reaches the setting rang of pressure reducing pilot valve, the pilot valve will automatically sense the outlet pressure and adjust the pressure of the back pressure chamber in the main valve, so the valve gate can be opened and conscqucntly maintains the outlet pressure.

Pressure Adjusting Range : 0.7~7 kgf/cm2
                                                           4~12kgf/cm2
                                                           (1kgf/cm2=14.2 psi)

Special order can be arranged for higher pressure adjustment range.

  • The pressure meter on the pilot valve shows the outlet pressure. When the outlet opens, the value of the pressure meter is lower.
  • When the outlet is used for large flow and the gate generates quick-close motion, the pilot valve will slowly respond to the main valve to close teh gate. Under this situation, the outlet pressure gets a little higher, and tiny pressure reducing valve can be added.

PRESSURE RELIEF VALVE
  • Pressure relief valve is installed on the outlet pipe of water supply pipeline.
    It can maintain safe water supply pressure inside the pipe and prevent pipeline
    and equipment damage caused by accidental escalation of water pressure.
  • When water pump stops functioning or pipeline gate suddenly closes,abnormal
    pressure forms inside the pipe. As the pressure gets over a certain safety limit,
    pressure reliet valve can open automatically and releases the water pressure
    above the safety limit, go as to ensure the safety of pipeline and equipment.
    When the pressure turns back within the safety limit, the pressure relief will close slowly.

Pressure Adjusting Range : 2~8 kgf/cm2
                                                          5~13kgf/cm2
                                                           (1kgf/cm2=14.2 psi)

Special order can be arranged for higher pressure adjustment range.

Utilization State of Pressure Relief valve

When water pressure inside the pipeline becomes greater than the spceified outlet pressure, the pressure relief pilot valve opens
and simultaneously releases the pressure in the back pressure chamber. At this time, the main valve gate is pushed open and
keeps the main valve in open state. When the pressure returns to the safety limit, the pilot valve colses simultaneously,
and the back pressure chamber in main pressure inside the pipeline can be maintained.
