Pressure Reducing Valve Pilot Operated Multi Functional

4Matic Offer High Flow Multi Functional Type Pressure Reducing Valves Suitable for Air, Water, Steam, Gas & Oil ect.

Features

  • Smart Design with High Flow Characteristics
  • Pressure reducing valve can be installed in water supply, air conditioning and fire control systems to maintain the Constant outlet pressure.
  • The pressure reducing valve used a sub-valve (pilot valve) to control the main valve. When the outlet pressure reaches the setting range of pressure reducing pilot valve, the pilot valve will automatically sense the outlet pressure and adjusting the pressure of the back pressure chamber in the main valve, so the valve gate can be opened and consequently maintains the out let pressure.
  • The pressure gauge on the pilot valve shows the outlet pressure. When the outlet opens, the valve of the pressure gauge will decrease.

Pressure Relief Valve ( Safety Valve ) Multi Functional

Features

  • 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 the water high pressure. When pressure returns to safety value, pressure relief valve will auto-matically close to ensure the safety of equipment.
  • Pressure Adjusting Range : 0.5 kgf/cm2 ~ 10 kgf/cm2 7 kgf/cm2 ~ 20 kgf/cm2
  • Applied Temperature : -15 ~ 100 OC 100 ~ 180 OC ( For Steam )
  • Valve Body Testing Pressure : 35 kgf/cm2 ( 1 kgf/cm2 = 14.2 psi )
  • Maximum Applied Pressure : 25 kgf/cm2   the outlet opens, the valve of the pressure gauge will decrease.

Direct – Activated Pressure Sustaining Valve Multi Functional

Features

  • Pressure sustaining valve is utilized when installing pipes for users. It primarily matches up with the minimum working pressure inside the tap water pipe, balancing up-stream and down-stream pressure during normalcy and emergency, and maintains constant pressure inside the pipe.
  • Pressure sustaining valve can sustain the maximum working pressure inside the pipe when installed in water supply areas.
  • Pressure adjusting range : 0.2 ~ 4 kgf/cm ,3 ~ 10 kgf/cm , (1 kgf/cm  = 14.2 psi)
  • The working pressure should be greater than 0.3 kgf/cm2 and gate fully open with 1.5 kgf/cm2, please check the pressure before installation.

Multi Functional Float Valve

Features

  • Float valve uses a sub-valve (floating ball switch) to control the main valve. When the water level elevates to the full water level set by sub-valve (floating ball switch), the sub-valve (floating ball switch) closes and the back pressure chamber inside the main valve accumulates pressure rapidly, which reversely pushes the piston valve to close. By this mechanism, the float valve can thus  control the water level. In order to save space inside the pool and for easy maintenance, it is recommended to install the float valve outside the pool.
  • The working pressure should be greater than 0.3 kgf/cm  and gate fully open with
  • 1.5 kgf/cm2, please check the pressure before installation.
  • Please remove impurities or metal dusts inside the pipe throughly. 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.
